Coffee and Cognitive Health: A Stimulating Blend for Longevity in Older Adults

In a groundbreaking study examining the intricate interplay between coffee consumption, cognitive function, and mortality risk in older adults, researchers have unveiled intriguing findings that may reshape our understanding of the popular beverage’s impact on health.

The study, titled “Coffee consumption and all-cause and cardiovascular mortality in older adults: should we consider cognitive function?” delves into the association between coffee and mortality, shedding light on the role cognitive function plays in this complex relationship.

The research, based on data from the National Health and Nutrition Examination Survey (NHANES) spanning 2011-2014, analyzed the coffee and caffeine consumption patterns of older adults and assessed their cognitive performance through various tests, including the CERAD-word learning test (CERAD-WLT), animal fluency test (AFT), and digit symbol substitution test (DSST). A global cognitive score was derived from these assessments using principal component analysis (PCA).

Intriguingly, the study revealed that individuals with cognitive impairment who reported abstaining from coffee exhibited the highest risk of all-cause and cardiovascular mortality compared to their counterparts. The findings suggest a complex relationship between cognitive function and coffee consumption, warranting a nuanced exploration.

For those with cognitive impairment in the AFT, a significant negative association between total coffee consumption and all-cause mortality was observed. The results extended to DSST and global cognition, indicating a potential protective effect of coffee on mortality in individuals with cognitive challenges. However, the study also uncovered a “U-shaped” association between coffee consumption and mortality in individuals with cognitive impairment in the CERAD-WLT, adding a layer of complexity to the findings.

Remarkably, the study also pointed towards decaffeinated coffee as a potential ally for those with cognitive impairment, showing an association with reduced mortality. This intriguing link between decaffeinated coffee and longevity in cognitively challenged individuals raises questions about the specific components in coffee that may contribute to these observed health benefits.

In conclusion, this comprehensive study suggests that the relationship between coffee consumption and mortality is significantly influenced by cognitive function. The findings highlight the need for further research to unravel the intricate mechanisms at play and may pave the way for personalized health recommendations based on an individual’s cognitive status. So, for coffee enthusiasts, the morning brew might not only be a source of alertness but also a potential elixir for a longer, healthier life.

Pink Bourbon, The Rising Star of Specialty Coffee

The specialty coffee industry thrives on the discovery of new and intriguing arabica coffee varieties, and it’s never more evident than at coffee competitions. In the final round of the 2023 World Barista Championship, two participants showcased the Pink Bourbon variety, known for its delicate pink hue and intricate flavor profile, which has been piquing the interest of coffee enthusiasts for some time now.

Pink Bourbon has been gaining popularity among roasters and coffee shops in recent years, but its mysterious origins leave much room for exploration. Can it achieve the same level of acclaim as Gesha or other similar varieties? To uncover more about Pink Bourbon’s allure and potential, I reached out to key players in the coffee industry.

  • Unearthing the Origins of Pink Bourbon

The origins of Pink Bourbon, like many other arabica varieties, remain a mystery. Rodrigo Sanchez Valencia, a producer at Finca Monteblanco and Aromas del Sur, provides insights into this enigmatic coffee. He’s often credited with helping discover Pink Bourbon. Rodrigo explains that his team at Aromas del Sur stumbled upon Pink Bourbon in 2013, believing it to be native to southern Huila in Colombia.

According to Rodrigo, Pink Bourbon first surfaced in the San Adolfo area of the Acevedo municipality in Huila during the 1980s, although the specifics of its origins remain unverified. This unique variety gained popularity when coffee leaf rust (la roya) plagued the region in the 1980s. Pink Bourbon proved to be disease-resistant and adaptable, making it a preferred choice among coffee producers.

  • Dispelling Previous Claims

It’s a common belief that Pink Bourbon is a natural hybrid of Red and Yellow Bourbon varieties, but recent research suggests otherwise. Café Imports published a groundbreaking article in late September 2023, revealing that genetic testing, in collaboration with RD2 Vision, indicates Pink Bourbon likely has roots in an Ethiopian landrace variety. However, it’s crucial to note that this research is not yet scientifically verified, leaving Pink Bourbon’s exact heritage shrouded in uncertainty.

  • The Challenge of Cultivating Pink Bourbon

Cultivating Pink Bourbon is no walk in the park, even in ideal conditions. Producers must meticulously care for these plants and ensure they are isolated from other varieties to ensure successful cross-pollination.

Rodrigo, having worked extensively with Pink Bourbon, highlights its resilience and productivity. “To date, we’re not aware of any diseases to which it’s susceptible,” he explains.

Boram Um, co-owner of Um Coffee Co. and Fazenda Um, reveals that Pink Bourbon’s growth experience can vary depending on the terroir. In his Brazilian farm, Pink Bourbon is cultivated under controlled and protected conditions due to its susceptibility to diseases and fungi.

Isaiah Sheese, owner of Archetype Coffee, who also used Pink Bourbon in the 2023 World Barista Championship, notes subtle differences in the physical characteristics of Pink Bourbon cherries. He attributes these variations to factors such as elevation and location.

One of the most distinctive traits of Pink Bourbon is its slight pink hue, a characteristic cherished by coffee enthusiasts.

  • The Flavor of Pink Bourbon

Pink Bourbon’s allure extends beyond its unique appearance to its complex and delightful flavor profile. Boram describes it as typically more acidic, reminiscent of citrus fruits, with delicate notes of white florals and honey-like sweetness.

Isaiah concurs, likening Pink Bourbon to washed Ethiopians or Panamanian Geshas, with flavors of floral, pink lemonade, honeysuckle, jasmine, and a silky, elegant texture.

Rodrigo, on the other hand, often detects tropical notes in Pink Bourbon, such as peach, papaya, melon, as well as floral notes like jasmine, rose, and green tea. He emphasizes its well-balanced body and acidity.

  • Enhancing Flavor Through Processing

As with other coffee varieties, the choice of processing methods can accentuate Pink Bourbon’s flavors. Rodrigo notes that Pink Bourbon cherries contain higher sugar content, making them adaptable to various processing techniques. He favors cold fermentation to improve complexity.

Boram found that anaerobic fermentation worked well with Pink Bourbon from his Brazilian farm, enhancing its sweet floral and honey notes. Isaiah, who sourced his Pink Bourbon from Colombia, appreciated the two-stage thermal shock fermentation process introduced by Diego Bermudez.

  • Roasting Pink Bourbon

Roasting Pink Bourbon demands a careful approach. Isaiah, who used a unique two-stage thermal shock process for his Pink Bourbon, adjusted his roasting technique accordingly. He also utilized the Stronghold S7 roaster, which differs from traditional drum machines due to its halogen-powered heat source.

Boram made temperature adjustments during roasting, given the climatic conditions in Brazil, to ensure proper development.

  • The Future of Pink Bourbon

The potential market for Pink Bourbon appears promising, with growing interest in this variety year after year. However, challenges in scaling up production may limit its availability in coffee shops and roasteries.

Rodrigo is optimistic about Pink Bourbon’s future in the Colombian specialty coffee sector, believing it will remain a vital variety. He is proud to be among the pioneering producers of this unique coffee.

Boram envisions the success of Colombian producers with Pink Bourbon encouraging its cultivation in other countries, including Brazil.

As the specialty coffee world seeks the next “it” variety, Pink Bourbon with its captivating qualities and evolving popularity has the potential to become the next darling of specialty coffee. However, this journey may take time.

New Research Warns of Peril to Coffee Industry Amid Climate Change

The coffee sector faces a growing menace, as per a recent investigation. This threat emanates from the consequences of climate change and the loss of pollinators, compounding the vulnerabilities of coffee growers and putting international trade in jeopardy.

Conducted by a team of scholars from the University College London (UCL), the study, featured in the latest edition of Science Advances, delves into the worldwide decline in the biodiversity of insect pollinators. It simultaneously scrutinizes its links to shifts in agricultural land use, particularly deforestation, climate change, food production, and the global trade network.

According to Tim Newbold, the lead author and a prominent figure in the UCL Biosciences department, “Our findings emphasize the immediate necessity for taking collective action on a global scale to mitigate climate change. We must also prioritize the preservation of natural habitats and curb land use changes to prevent any detrimental effects on insect pollinators.”

The study, supervised by UCL’s Ph.D. researcher Joe Millard, who is presently affiliated with the Natural History Museum in London, hinged on a dataset encompassing over 2,600 locations and 3,080 distinct pollinator species. The results of the research suggest that regions in the tropics face the highest threats to crop production stemming from the loss of pollinators due to climate change and changes in agricultural land use.

The authors of the study articulated, “Localized risk is most pronounced and poised to surge rapidly in areas of sub-Saharan Africa, northern South America, and Southeast Asia. Climate change and the shifts in land use present a potential peril to human well-being through pollinator loss alone.”

The research paper probes the repercussions of pollinator diminishment on several significant crops that serve as staples and economic cornerstones. Among them, coffee and cocoa have been singled out due to their susceptibility in agriculture and their pivotal role in the global economy.

The study points out that coffee, in particular, confronts a precarious combination of high production risks and considerable economic value. This scenario hints at possible economic hardships in regions where coffee is cultivated unless the pollination service can be replaced economically. Similar to cocoa, coffee cultivation is the backbone of income for millions of small-scale farmers and their families in tropical regions. Thus, the escalating production risk arising from pollinator loss may lead to heightened financial insecurity for some of the world’s most vulnerable populations.

New study: Coffee helps with weight loss, but under one condition

A recent publication in The American Journal of Clinical Nutrition shows that coffee, so beloved by many, can help in the process of losing weight, but in order for it to have an effect, one condition must be met.

As part of their research work, the purpose of which was to trace the connection between coffee consumption, weight changes and the addition of sugar and cream to the drink, experts from the United States studied data from more than 150 thousand participants in group studies.

After analyzing the habits of the subjects, experts found that every cup of coffee without sugar contributed to weight loss, and adding cream had almost no effect on weight change. At the same time, as the researchers noted, adding even one spoon of sugar was associated with subsequent weight gain. This association was stronger for younger people with higher body mass index.

The scientists’ findings state that drinking coffee without sugar is inversely proportional to weight gain, and adding sugar to the drink eliminates all the benefits of drinking it for weight control.

  • Study details

Changes in Coffee Intake, Added Sugar and Long-Term Weight Gain – Results from Three Large Prospective US Cohort Studies

Background

Consumption of both caffeinated and decaffeinated coffee has been reported to attenuate long-term weight gain. Whether the association between coffee consumption and weight gain depends on the addition of sugar, cream or coffee whitener remains unclear.

Objective

We aimed to study the associations between changes in coffee consumption, caffeine intake and weight changes by considering the addition of sugar, cream or a non-dairy coffee whitener.

Methods

We used three large prospective cohorts – the Nurses’ Health Study (1986 – 2010), Nurses’ Health Study II (1991 – 2015) and Health Professional Follow-up Study (1991 – 2014). We applied multivariable linear regression models with robust variance estimators to assess the association of changes in coffee habits within each 4-year interval with concurrent weight changes. Results across the three cohorts were pooled using inverse-variance weights.

Results

After multivariable adjustment, each 1 cup per day increment in unsweetened caffeinated coffee was associated with a reduction in 4-year weight gain of -0.12 kg (95 % CI: -0.18, -0.05 kg) and of -0.12 kg (95 % CI: -0.16, -0.08 kg) for unsweetened decaffeinated coffee. The habits of adding cream or non-dairy coffee whitener were not significantly linked to weight changes. Adding a teaspoon of sugar was associated with a 4-year weight gain of +0.09 kg (0.07, 0.12 kg). Stratified analyses suggested stronger magnitude of the observed associations with younger age and higher baseline body mass index (BMI). Neither caffeine nor coffee modified the association of adding sugar to any food or beverage with weight changes.

Conclusions

An increase in intake of unsweetened caffeinated and decaffeinated coffee was inversely associated with weight gain. The addition of sugar to coffee counteracted coffee’s benefit for possible weight management. On the other hand, adding cream or coffee whitener were not associated with greater weight gain.

Specific dates that should be taken into account… When do we drink coffee?

Many people continue to drink coffee immediately after waking up because of its effective role in improving mood, but there is scientific evidence that confirms that drinking coffee immediately after waking up is not “correct,” and that benefiting from it comes from drinking it at the appropriate time.

Coffee is a favorite drink among all people, including Germans, which is confirmed by estimates that 73 percent of Germans drink coffee daily. While the percentage of Germans who do not drink coffee at all is only 6 percent. There are many studies on this drink compared to other drinks. Most of the test results were positive and clearly confirm that this drink is a completely healthy stimulant.

Coffee strengthens memory and prevents diabetes. It contains antioxidants and provides the body with a large amount of energy. It also reduces the risk of developing serious diseases, including liver cancer, skin cancer, and nerve diseases, which is something that many may not know.

The results of studies may sometimes conflict about the effect of coffee on some diseases, such as cognitive impairment, dementia, and Alzheimer’s, but most of these studies confirm that coffee protects against these diseases. In addition, researchers have proven in two recent studies that drinking coffee and tea together has a positive effect on cognition. Note that drinking tea alone does not effectively affect the problem of cognitive impairment, but a recent study confirmed that drinking coffee between 3 to 5 times a day in middle age helps reduce the incidence of dementia by 65 percent, according to what was reported on the German “Gesundheit Identity” website. In health affairs.

It is not recommended to drink coffee immediately after waking up

There is no doubt that the delicious taste of coffee and its ability to improve the mood every morning prompts many people to continue drinking it daily. According to the German “Gesunde Ernerung” website, obtaining the full benefits of coffee depends on knowing the appropriate time to drink it. To benefit from morning coffee, researchers advise not drinking it immediately after waking up. Rather, you must wait a little and then drink it. Researchers attribute this to the fact that the adrenal gland secretes, upon waking, the hormone cortisol, known as the “stress” hormone, and this hormone helps the body regain the ability to perform its functions, thus providing the body with its energy naturally. By consuming caffeine immediately after waking up, the level of energy in the body increases excessively.

On the other hand, drinking coffee two hours after waking up gives the body more energy when its natural energy begins to gradually decline. Which means that the most appropriate time to drink morning coffee and benefit from the effect of caffeine on the body is around eight-thirty, when waking up at seven, for example.

Coffee and Tea: Your Secret to Staying Strong as You Age

A recent study suggests that consuming coffee and tea in midlife may be linked to a reduced risk of physical frailty in later years. The study conducted in Singapore found that adults who consumed higher amounts of caffeine through coffee or tea had significantly better physical functioning in their later years.

The study was led by Professor Koh Wen Boon from the Longevity Medicine Program at the Yong Loo Lin School of Medicine, National University of Singapore. It was based on data collected from over 12,000 participants aged between 45 and 74 years over a 20-year follow-up period.

Published on July 21, 2023, in the Journal of the American Medical Directors Association (JAMDA), participants were first interviewed in midlife, with an average age of 53 years, using structured questionnaires from 1993 to 1998. During these baseline interviews, participants were asked about their habits of consuming caffeine-containing beverages like coffee and tea, as well as foods like chocolate, in terms of frequency and portion size. They also provided information on their social and demographic characteristics, medical history, height, weight, dietary habits, physical activities, and sleep duration.

In the second follow-up interviews conducted from 2006 to 2010, participants were asked to report their weight, among other questions. During the third and final follow-up interviews, conducted from 2014 to 2017 when the average age of the participants was 73 years, they were asked, among other things, about their energy levels and were assessed for handgrip strength and the time taken to complete the Timed Up and Go (TUG) test.

Physical frailty was defined as having two or more of the following four elements:

  1. Weight loss (more than 10% loss between the second and third follow-up).
  2. Fatigue (if the answer was yes to the question).
  3. Slow performance of tasks.
  4. Weak handgrip strength.

Coffee and tea were the main sources of caffeine consumption in this group, representing 84% and 12% of total caffeine intake, respectively. A total of 68.5% of participants in this group consumed coffee daily. Among them, 52.9% drank one cup daily, 42.2% consumed two to three cups daily, while 4.9% drank four cups or more daily.

As a result, participants in the study were divided into four categories based on the amount of coffee they consumed: those who didn’t drink coffee daily, those who drank one cup daily, those who consumed two to three cups daily, and those who drank four cups or more daily. Tea drinkers were also divided into four categories: those who didn’t drink tea at all, those who consumed it at least once a month, those who consumed it at least once a week, and those who drank tea daily.

Professor Koh, who led the study, stated, “Our results show that consuming coffee or black and green tea in midlife is independently associated with a significant reduction in the risk of physical frailty in later life. Participants who drank four cups or more of coffee daily significantly lowered their chances of physical frailty in later years compared to those who didn’t drink coffee daily. Participants who consumed black and green tea daily also had a significantly lower risk of physical frailty compared to those who didn’t drink tea.”

The researchers also evaluated the relationship between caffeine consumption and the risk of physical frailty in later years. Consuming larger amounts of caffeine was associated with a reduced risk of physical frailty, regardless of the source of caffeine. Among the four components of physical frailty, the associations were strongest in the tests measuring handgrip strength and rope tightness, compared to self-reported measures of weight loss and fatigue.

Interestingly, in other experimental studies, caffeine was found to promote muscle cell proliferation and improve muscle weight in mice. In addition to caffeine, coffee and tea also contain biologically active, antioxidant-rich polyphenols that have anti-inflammatory properties, and are associated with a reduced risk of diseases that increase the risk of physical frailty, such as diabetes, heart and vascular diseases, obesity, and neurodegenerative diseases.

However, further research is needed to determine the actual components and mechanisms underlying the link between coffee/tea and human physical function, as Professor Koh added, “Coffee and tea are essential beverages in many societies worldwide. Our studies suggest that consuming these caffeine-containing beverages in midlife may be associated with a reduced risk of physical frailty in later life. Nevertheless, more research is needed to confirm this.”

Coffee Sensitivity: Why Some People Don’t Enjoy Coffee

Coffee is one of the most popular beverages in the world, but not everyone enjoys it. Some people find coffee to be too bitter, while others experience negative side effects such as anxiety, insomnia, and headaches.

A growing body of research suggests that our sensitivity to caffeine is largely determined by our genes. One gene, CYP1A2, plays a particularly important role in caffeine metabolism. People with two copies of the “fast” variant of CYP1A2 metabolize caffeine quickly and are less likely to experience negative side effects. People with two copies of the “slow” variant of CYP1A2 metabolize caffeine slowly and are more likely to experience negative side effects.

In addition to genetics, other factors such as age, weight, and lifestyle can also affect caffeine sensitivity. For example, pregnant women and people who are taking certain medications may be more sensitive to caffeine.

For people who are sensitive to caffeine, there are a few things they can do to reduce their intake and avoid negative side effects. One is to limit their consumption of coffee and other caffeinated beverages. Another is to choose decaffeinated coffee or tea. People can also try drinking coffee earlier in the day to avoid disrupting their sleep.

If you are concerned about your caffeine sensitivity, it is important to talk to your doctor. They can help you determine if caffeine is contributing to any health problems you are experiencing and can provide advice on how to manage your caffeine intake.

Tips for people with coffee sensitivity:

  • Limit your intake of coffee and other caffeinated beverages.
  • Choose decaffeinated coffee or tea.
  • Drink coffee earlier in the day.
  • Talk to your doctor about your caffeine sensitivity and how to manage it.

What happens to your body when you drink coffee every day?

Coffee has been praised for centuries, either for its taste or its fresh aroma, and some have even considered it one of the greatest “inventions” in the world.

For many people, a cup of coffee is a daily routine, where they drink it before even thinking about doing anything in their day, and for others, there’s nothing better than having it in the middle of the day.

According to a survey by market research firm Drive Research published in July last year, nearly 75% of adults in the United States drink coffee daily.

But a cup of coffee may be more useful than just a daily routine or giving someone the energy to get through the day easily and focus. According to the United States Department of Agriculture, it is a natural source of phosphorus and magnesium.

If you are one of the many people who drink coffee every day, it is important to know what this habit does to your body, both in terms of benefits and risks, according to an article on the website “Eating Well” that compiled both from many studies.

Health benefits of coffee

  • More energy

Coffee beans contain caffeine, a natural stimulant that can help you feel more alert, as it stimulates the central nervous system, which helps people get more energy.

  • Improved mood

Many coffee lovers agree that a good cup of coffee is a ticket to happiness. And there is actual data to support this idea.

A study published in 2019 in the journal “Physiology and Pharmacology Basic and Clinical” found that healthy adults experienced an improvement in mood 30 minutes after consuming caffeine.

Drinking regular coffee led to a more significant improvement in mood than drinking decaffeinated coffee.

  • Reduced risk of Alzheimer’s disease

Coffee also contains a number of biologically active polyphenol compounds that may support certain aspects of our health, including brain health.

Evidence published in 2021 in the journal “International Journal of Molecular Sciences” suggests that coffee consumption may be associated with a lower risk of developing some neurodegenerative conditions such as Alzheimer’s disease, Parkinson’s disease, and dementia.

  • Heart and blood vessels

According to a study published in 2018 in the journal “Journal of Agricultural and Food Chemistry,” daily coffee consumption is associated with a lower risk of developing cardiovascular disease.

  • Improved thyroid function

A study published in 2023 in the journal “Nutrition” found a potential link between moderate caffeine intake and improved thyroid function among people with metabolic disorders.

Potential risks

While coffee consumption is associated with some great benefits, there are also some potential risks.

  • Anxiety

Excessive caffeine intake is associated with an increased risk of anxiety, according to research published in 2020 in the journal “Nutrients”.

Another study published in 2021 found that consuming larger amounts of caffeine is also associated with sleep disturbances and decreased appetite.

  • Increased risk of fractures

Coffee consumption is associated with negative effects on bone health, according to some data, and the more coffee is consumed, the higher the risk of fractures, especially for older adults.

  • Potential complications of pregnancy

Organizations such as the American College of Obstetricians and Gynecologists suggest that it is safe to consume up to 200 milligrams of caffeine per day during pregnancy.

However, new evidence suggests that even small amounts of caffeine may come with some risks. An analysis published in the journal “BMJ” in 2021 found that 14 studies suggest that caffeine intake during pregnancy is associated with an increased risk of miscarriage and low birth weight.

  • Potential increase in blood pressure

Regular coffee consumption is often associated with both positive and negative effects on blood pressure.

While short-term consumption may cause a slight and temporary increase in blood pressure, studies, such as those published in 2022 in the journal “Blood Pressure,” show that long-term consumption does not lead to sustained increases in blood pressure.

However, individual responses to coffee may vary, and those with specific health conditions, or who are at risk for high blood pressure, should consult a doctor.

Conclusion

In conclusion, coffee has both potential benefits and risks. Consuming up to 400 milligrams of caffeine per day, which is about four cups of coffee, is generally considered safe for most adults. However, it is important to be aware of the potential risks, especially for pregnant women, people with anxiety or mood disorders, and those with certain health conditions.

The coffee industry… innovation and luxury

Innovation and Luxury

Garfield Kerr

CEO Mokha 1450

At Mokha 1450, innovation and luxury go hand in hand. In fact, the latter is often intormed by the former, as luxury by definition equires innovation as the dilferentiator to the commonplace,whether that be expressed through superior ingredient or craftsmanship. For the first iteration of the Barista Craf Magazine,it is the innovation of Mokha 1450’s baristas that takes center stage. As they were tasked through an internal competition with curating a coffee experience tike no other; one that is niquely targeted to the flavor profile preterences of the fine inhabitants of the United
Arab Emirates (UAE).

While numerous studies have shown that coffee preferences amongst countries can be identified and quantified, there are differences of course within any populace, hence cach similar segment of the UAE coffe consuming public represents a discrete circle in a Venn diagram. Therefore, the monumental task of the barista is that of identilying where those circles overlap and curate a coffee whose flavor profile highlights these unions. The resull of this exploration is an experience like no other, a coffee entirely new that would not exist had the challenge not been presented and
accepted in the first place, a coffee whose origin will not be shared so as to remove the limitations aof expectations as well as to highlight the barista alone. The outcome is a unique coffee that is a luxury to be shared with our clients, whom we recognize as the connoisseurs that they are, and whom will be the final arbiters of whether our baristas have truly hit the mark.

Another equally important innovation on display within this, the seminal issue of the three-part magazine, is that of revenue sharing with our baristas. Baristas in the UAE are some of the most talented in the world, as exemplified through their work in one of the world’s leading specialty coffee markets as well s their national and international Specialty Coffee Association coffee competition championships. Yet, because of inscrutable market conditions, the baristas in the UAE are not paid a salary that is commensurate with their counterparts in other leading specialty coffee
regions. To solve this dilemma, we offer an innovative and new approach, as the limited-edition coffees that are produced by the top three finalists in the aforementioned competition will feature with a compendium magazine with a percentage of the revenue from coffee bag sales going directly to the barista who crafted their own unique vision of the perfect coffee that most suits the to UAE’s palate.

If you are reading this, you may have had the luxury of experiencing the coffee produced by Mohamed Minran, the first in the three-part series. The flavor profile of Minran’s coffee presents of with notes of cherries. honey, exceptional Sweetness, fruity. with a milk chocolate finish and an added dose of innovation and luxury.

 

New research finds compounds which cause fruit flavours in fermented coffee – what could this mean?

For some years now, experimental processing techniques have been a hot topic in the specialty coffee sector. These processing methods tend to result in more complex and unique sensory profiles, which also have more fruity flavours. In turn, they are becoming more and more popular among coffee professionals and enthusiasts alike.

Fermentation in processing plays a key role to create these fruitier flavours. However, up until recently, little was known about how this happens.

Last month, Zurich University of Applied Sciences’ (ZHAW) Coffee Excellence Centre presented its study on fermented coffee flavours at the American Chemical Society Spring 2023 meeting. As part of its findings, ZHAW identified three chemical compounds which directly contribute to fruity flavours and aromas in fermented coffee.

Naturally, this raises a lot of questions. But one of the more prominent is how might this research influence coffee processing methods in the coming years?
WHY DOES FERMENTATION MAKE COFFEE TASTE MORE FRUITY?
As the specialty coffee market has grown and diversified over the past few years, so have processing methods, too. Recently, more and more farmers have started using controlled fermentation to enhance coffee quality and flavour.

Generally speaking, this is done in two main ways. These are anaerobic or aerobic fermentation (which are different due to the absence or presence of oxygen). The removal of or presence of oxygen triggers several chemical reactions which create various acids and alcohols.

As a result, the sugars in the fruit of the coffee will break down over a prolonged period of time. This means the coffee will taste much sweeter and more complex, with more fruity and “winey” aromas and flavours.

We know that using particular yeasts and strains of bacteria during coffee fermentation can create specific sensory profiles. However, so far, there has been a somewhat limited understanding of which particular chemical compounds are responsible for creating certain flavours and aromas.

Looking at different processing methods
In its recent research, ZHAW outlined how it identified three distinct chemical compounds which create “the intense fruity flavour and the raspberry scent of a fermented coffee”.

Sasa Sestic is the founder and CEO of Project Origin in Australia, which helped to fund the research project. He also provided the coffee for the study: a green tip Gesha from Iris Estate in Panama, which Sasa co-owns with Jamison Savage.

“If we can understand how volatile compounds are formed at farm level, then we can understand how to highlight them through processing methods,” he says. “We unlock the potential to emphasise terroir with the support of science.”

A team led by Dr. Chahan Yeretzian, Head of the Coffee Excellence Centre, and Dr. Samo Smrke, Head of Coffee Transformation at the Coffee Excellence Centre, sorted the coffee into three different categories. These were according to processing method:

Washed processing (producers remove all flesh and mucilage from the beans before drying)
Pulped natural carbonic maceration processing (producers remove skin of the fruit while pulp is left intact)
Natural carbonic maceration
Similar to processes used in wine making, carbonic maceration has become more prominent in specialty coffee. For example, Sasa used a carbonic macerated Sudan Rume variety in his winning 2015 World Barista Championship routine.

The process involves placing cherries in sealed tanks and flushing them with carbon dioxide to remove any residual oxygen. Like other fermentation processing methods, carbonic maceration often results in more bright, wine-like, and fruity flavours.
Analysing different coffees
As part of the study, each coffee was brewed the same way. In order to analyse the aroma of all samples, ZHAW used a process known as gas chromatography-olfactometry (GC-O).

This is when scientists uses a gas chromatograph to separate individual components of a mixture or substance. They then pass through a mass spectrometer to identify each individual component.

Following this, human assessors were then asked to describe any aromas they could pick up on.

Chahan and Samo explain why this type of analysis was also used in conjunction with gas chromatography.

“We saw descriptors, such as ‘extremely sweet’, ‘crazy like strawberry’, and ‘artificially sweet’,” they say. “All the panellists were able to point out this characteristic in the carbonic macerated coffee.

“However, when examining the mass spectrometry data of the same coffee, at the exact same time and position in the chromatogram as panellists detected this unique and strong aroma, we were not able to detect compounds that could be attributed to those flavours,” they add.

“This confirms what flavour scientists have known since long: our nose outperforms even the best instrument on some of these low-threshold aro

ma active compounds that are so important to our understanding of the flavours we perceive,” Chahan and Samo continue.
COULD RESEARCH INFLUENCE MORE PRODUCERS TO STANDARDISE PROCESSING TECHNIQUES?
The results of ZHAW’s study concluded that six chemical compounds are responsible for fruity aromas and flavours in fermented coffee. However, the researchers stated that they were only able to identify three of them:

2-methylpropanal
3-methylbutanal
Ethyl 3-methylbutanoate
“One very intense fruity smelling compound, ethyl 3-methylbutanoate, stood out in the natural carbonic macerated coffee,” Chahan and Samo say. “It was found to be 125-times more abundant than in the washed coffee.”

It’s important to note scientists involved in the study emphasise that further research is necessary to identify the other three compounds. Moreover, we also need to know how these compounds are formed in the first place.

Farmers have been using particular yeasts, bacteria, and microorganisms during processing to control and enhance coffee flavour for some time now. But at the same time, this is clear evidence that specific chemical compounds result in the more characteristic fruity flavours we associate with experimentally processed coffees.

Ultimately, this leads us to several important questions. Arguably, however, the most important is if we know which compounds cause certain flavours, what does this mean for farmers?

Could producers develop and use more standardised processing methods? And would this be especially apparent with processing methods that result in more targeted and specific flavour profiles?

A question of value addition
Once producers know which specific compounds cause certain flavours, they can potentially process coffee with more intent and control. In turn, they can target particular sensory profiles. Eventually, this could lead to producing experimentally processed coffee on a larger scale – potentially allowing producers to add more value to their coffee.

“We first need to know how much potential a coffee has in the first place, in terms of flavour profile and volatile compounds,” Sasa says. “Then, through processing, we can determine how the amount of more desirable volatile compounds can be increased, so we can experience new flavours and aromas.”

Chahan and Samo agree, saying: “The practical implication of our study is that it provides farmers with new ways to improve the quality and quantity of fruity notes through post-harvest processing.

“This may eventually also help producers in a fast-growing market of fermented coffee to take more informed positions, as allegations on coffees ‘infused’ with fruit are surfacing,” they add.

The other side of the coin
However, with this in mind, we also need to acknowledge that not all coffee farmers have the ability to try fermentation and other experimental processing methods. These processing techniques often require significant upfront investment and specialist equipment which some producers may not have access to.

Moreover, for many smallholder farmers, the risks of such experimental processing methods may outweigh the benefits. Although these coffees can sometimes result in higher prices, they are typically more expensive to produce than more “traditional” processed coffees.

Similarly, without proper quality control protocols in place, producers may end up creating less desirable sensory profiles of fermented coffee – such as sour, overly fermented, or rancid flavours.
Although experimentally processed coffees are certainly becoming more popular, they only represent a fraction of the wider coffee market.

However, that’s not to say that research like this doesn’t benefit farmers who produce these kinds of coffees. In fact, with further studies conducted in the future, it could be possible to create more “accessible” experimental processing methods – just as long as farmers have access to the right infrastructure and support.

Do specialty coffee consumers actually want to be more connected to farmers?

It’s fair to say that many specialty coffee brands base their marketing strategies around the idea that coffee consumers want to be more connected to farmers. These branding techniques largely revolve around disseminating more information about where coffee comes from, including the farmers who grow it.

The majority of specialty coffee professionals want to know as much information about origin as possible. This includes processing method, variety, altitude, and terroir. And while many coffee businesses believe that consumers also want to know the same information, is this really an accurate assumption?

To learn more, I spoke to Kosta Kallivrousis of Algrano, Marianella Baez Jost of Café con Amor, and Pedro Miguel Echavarría of Pergamino Coffee. Read on to learn their insights on whether consumers want to be more connected to origin.
THE ROLE OF FARMERS IN SPECIALTY COFFEE MARKETING
If you walk into almost any specialty coffee shop in any country around the world, you’re likely to see some kind of recognition of or homage to coffee farmers. This can range from photos of pickers on farms on the walls to detailed information about producers and co-operatives on coffee packaging.

In light of this, it certainly rings true that specialty coffee shops and roasters want to make sure that their products are connected to producers in some way. But why is this?

Forging connection to origin: a specialty “special”
One of the main selling points of specialty coffee is that it is more sustainable, traceable, and transparent than commodity-grade coffee. Therefore, it’s essential that roasters and coffee shops are able to bridge the gap between producers and consumers in order to communicate these attributes more effectively.

Kosta Kallivrousis is the Sales Manager at Algrano in the US. He tells me when specialty coffee brands seek to set themselves apart from competitors, marketing plays an instrumental role.

“A lot of specialty coffee branding and marketing is about showcasing what makes you distinctive,” he says. “It’s an industry that was born from marketing, rather than consumer demand.”

Marianella is the co-founder of Farmers Project Specialty Coffee and a producer at Café con Amor in Costa Rica. She agrees, saying that specialty coffee brands tell the stories of producers as a way of differentiating themselves from commodity-grade coffee companies.

“It demonstrates that you have a direct relationship with suppliers, which means as a brand you have more knowledge and your coffee is more traceable,” she tells me. “This helps to elevate the quality perception of your coffee, and shows that you’re going the extra mile [when sourcing].”

Demonstrating sustainable practices effectively
Displaying photos of coffee farms in shops or on websites, as well as providing information about a coffee’s origin, allows roasters and other coffee businesses to indicate that they have good relationships with their producers.

Pedro is the General Manager at Pergamino Coffee in Colombia. He explains that most specialty coffee brands want to demonstrate that they source and purchase their products fairly and sustainably.

“Translating the complexities associated with this into a simple marketing tactic is incredibly difficult – even for the most knowledgeable and educated consumers,” he says.

In recent years, a growing number of specialty coffee consumers do want to be reassured that the brands they buy from are complying with good environmental and ethical practices. At the same time, however, it’s fair to assume that some of these consumers aren’t familiar with what these practices really entail so communicating them effectively can be a challenge.

Romanticism and fetishisation
There’s no doubt that providing consumers with more information about origin is a valuable way for farmers to receive worthy credit for their hard work. However, it can quickly turn into “romanticism” if not carried out effectively. This leads some consumers to have idealised views of coffee farmers. Ultimately, a coffee farm is a business, and consumers should view them that way, too.

“Marketing can present a very blurry picture of the reality which producers face,” Marianella explains. “It’s difficult for consumers to discern between what is real and what is smoke and mirrors.”

She tells me that she once saw pictures of her farm on a brand’s website. However, she had never worked with them, and wasn’t even aware of them. Marianella explains that when she emailed them, they stated that they didn’t always know where their photos came from.

“This means some companies can make false claims by telling a story, but they have never even visited that country,” she adds.

Moreover, the use of certain images can perpetuate the idea of the “impoverished” or “exotic” coffee farmer. While some smallholders across the Bean Belt certainly live below the poverty line, this isn’t the case for all producers. Pushing narratives like this, as well as the idea that Western consumers are “saviours”, often creates widespread false perceptions about coffee producers –resulting in their fetishisation.

“The majority of people in the specialty coffee industry want to make a difference and do some good,” Kosta says. “However, the ways of doing so can be complicated.

“Is there consent from farmers to use their images and stories?” he posits. “They need to actually add value to producers, so they should be compensated, or at the very least, they should create these marketing strategies in partnership with farmers.”
WHAT DO SPECIALTY COFFEE CONSUMERS REALLY WANT?
In line with being more connected to origin, there are a number of purchasing factors which specialty coffee consumers tend to value the most.

First quality, then sustainability
The National Coffee Association’s 2022 National Coffee Data Trends Specialty Coffee Report report states that:

Around 69% of specialty coffee consumers say they are more likely to buy coffee because it’s fresh
An estimated 64% of respondents stated that paying farmers a fair price is important
Some 57% said proper treatment of farm workers influences their purchasing decisions
Kosta, meanwhile, tells me that he thinks consumers’ interest in paying producers a higher price could be inherently linked to alleviating guilt regarding economic and social inequity between themselves and producers.

“Maybe buying some coffee to address that, even in a small way, helps to absolve some of that guilt,” he says.

Building trust
Pedro believes that rather than explaining complex issues, such as the volatility of the C price, consumers want reassurance that the brands they buy from have ethical business practices.

Ultimately, this widens the gap between consumers and producers, rather than closing it. Consumers aren’t able to know the full extent of challenges which producers face in origin countries. And given the geographical distance between the two – and potential wide economic disparity – this is understandable.

“I don’t think that coffee consumers want to be more connected to farmers, per say,” Marianella says. “However, they do want to be more knowledgeable about the product: where it comes from, how it’s produced, and whether it was grown and sourced ethically.”

She tells me that Café con Amor runs a number of initiatives which directly benefit the local farming community. Marianella explains that she uses social media to show her customers how the programmes are impacting communities. She says this helps to build more trust with the consumer.

Smaller roasters with shorter supply chains tend to be able to do this more effectively than larger brands. Generally speaking, this is because they are in direct contact with producers. In turn, this can create more of a connection with consumers.

Traceability
In recent years, it’s become increasingly apparent that more and more consumers want to know where their coffee comes from.

“We need real traceability,” Marianella says. “Customers don’t need certifications and seals that tell them their coffee is sustainable. They want more concrete information that’s practical, honest, and specific.”

Pedro agrees saying: “There’s a big percentage of our loyal customers who really care, and ask about origin, farmers, our sourcing strategy, and how we pay premiums for certain coffees.

“Other people, however, may not have this level of knowledge about coffee, nor the time or interest to dig deeper,” he adds.

Pedro also points out that it’s presumptuous to believe that every consumer will have an in-depth knowledge of the coffee industry and how it operates.

“If we’re going to measure every consumer by that standard, then we should also do the same with ourselves,” he says. “Do we also know everything about the coffees we source? It’s hypocritical in a way.”
HOW CAN SPECIALTY COFFEE BRANDS LEVERAGE CONSUMER BEHAVIOUR TO CREATE REAL IMPACT FOR FARMERS?
There seems to be somewhat of a disconnect between what coffee consumers really want and what the specialty coffee sector would like them to want.

I asked Kosta, Marianella, and Pedro how brands can create real impact at origin through their marketing strategies.

Commitment and accountability
“What the specialty coffee industry suffers from the most is the relentless search for innovation – the latest roast profile, variety, or processing technique, for instance,” Kosta says. “But the thing that’s missing is commitment.

“The reality is that the coffee industry steers the ship,” he adds. “So we have a big responsibility to remain accountable and stay true to our social and environmental commitments.”

Technology and traceability
“Technology helps to resolve a lack of traceability by connecting roasters to origin,” Marianella explains. “For example, we can connect through mobile apps and connect from our farm with roasters all over the world.

“The possibilities of having face-to-face conversations, albeit online, add another layer of forging a direct relationship with origin,” she adds.

Pedro advises roasters to build their sourcing models around how they want to integrate sustainability into their business model. They can then create marketing strategies around that – not the other way round.

He also urges consumers to make sure that the coffees they buy (particularly blends) are sourced ethically.

“For example, there’s a lot more work that needs to be done in terms of transparency when it comes to blends than microlots,” he says.

Forging more trust
“For any business, trust is one of the hardest things to achieve and one of the easiest things to lose,” Pedro says. “You add real value when consumers trust the brand they’re buying from.

“Every roaster has to look within and ask themselves if they feel good about their buying practices – and communicate that,” he adds. “In an era of information, if there are any malpractices in your supply chain, this trust can be jeopardised.”

On a similar note, Kosta explains that portraying an “imaginary” connection with origin can be a form of fetishising. In turn, it can be a betrayal of consumers’ trust.

“Ultimately, if a marketing strategy ends up benefiting the company and not the communities it promotes, it becomes false advertising and is an abuse of customer trust,” he says.
The issues are complex and difficult to break down. However, it remains unclear whether the specialty coffee industry’s social and environmental goals are a response to consumer demand, or whether they emerged to influence it.

Either way, it’s clear that the majority of specialty coffee drinkers do want to know where their coffee came from, who grew it, and if they are being treated fairly.

Moving forward, specialty coffee brands need to make sure that their marketing strategies remain honest, ethical, and fair. For consumers, demanding more traceability and transparency from brands is the best way to play a role.
