Age Affect How You Taste Coffee: Exploring the Multifaceted Nature of Coffee Flavor Perception

The experience of flavor in coffee is shaped by an array of elements, from the temperature at which it’s brewed to the purity of the water and the elevation at which the coffee is grown.

Yet, discerning the subtler notes of a coffee’s profile demands a sophisticated palate, honed through exposure to a breadth of age affect how you taste coffee with different origins, cultivars, and processing techniques.

Cuppings are a principal venue for industry experts to sample and assess coffee. Nonetheless, a critical but often neglected factor in this evaluation is the taster’s age.

Scientific evidence points to the fact that our sensory perception, specifically our sense of smell and taste, tends to evolve with age, affecting the way we experience the flavor of coffee.

This leads to a pivotal inquiry: Should the age of professional cuppers be considered when conducting coffee cuppings and assigning scores?

To delve into this question, I engaged in conversation with two industry professionals – Gary Au, co-founder of Urban Coffee Roasters in Hong Kong, and Nick Castellano, Product Marketing Specialist at Cropster – to gain their perspectives.

For those interested in developing their cupping expertise, our beginner’s guide to cupping coffee and enhancing your palate may also prove to be a valuable resource.

Navigating the Evolution of Taste Perception with Age

The decline of our sensory abilities is a natural part of aging, with the pace of deterioration influenced by factors such as health conditions and the availability of healthcare.

While the common discourse on aging often focuses on the loss of hearing and vision, it’s important to note that our olfactory and gustatory senses—responsible for smell and taste—are similarly vulnerable.

Research, including a notable 2006 study, indicates a noticeable decline in these senses starting around age 60, and by age 70, many experience a significant reduction in their ability to differentiate flavors, which inevitably impacts the enjoyment of complex flavors, such as those found in age affect how you taste coffee.

This sensory impairment is thought to cause the body’s sensory organs to regenerate more slowly over time


This sensory degradation is attributed to a reduction in olfactory receptors and a slower regeneration of receptor cells over time, causing aromas and flavors to become less distinct.

In contrast, the sensory faculties of children are remarkably acute, with a particular sensitivity to sweetness and saltiness. Findings from a 2005 study by the Monell Chemical Senses Center revealed that infants have an innate ability to detect and often prefer sweeter tastes.

Yet, it is between adolescence and adulthood that our palates typically expand and mature. This development is fostered by exploring a diverse array of foods and cuisines, which acquaints us with a broader spectrum of flavors and textures, refining our recognition of the five fundamental tastes: sweet, salty, sour, bitter, and umami.

Exploring Beyond Traditional Coffee Flavor Descriptors

When delving into a coffee’s sensory profile, we traditionally consider five foundational attributes: acidity, sweetness, bitterness, body, and aftertaste. Yet, beyond these core characteristics, specific tasting notes come into play, offering a more nuanced exploration of flavor.

The Specialty age affect how you taste coffee Association’s Flavor Wheel is a tool widely used by professionals to pinpoint particular attributes and flavors in age affect how you taste coffee. Despite its utility, the Flavor Wheel faces criticism for its tendency to reflect European and North American taste preferences more than those from coffee-producing regions.

Introduced in 1995 and subsequently updated, the Flavor Wheel now encompasses a richer lexicon of 110 descriptors, covering flavor, texture, and aroma. For example, the “fruity” section alone boasts four subcategories, each with additional divisions, featuring descriptors such as raisin, cherry, coconut, and lemon.

While chocolate, caramel, nuts, and fruit are familiar notes regularly featured on coffee packaging, there’s been an undeniable trend among specialty roasters toward embracing more unconventional flavor notes in recent times.

But what’s driving this evolution toward more unique and specific flavor notes? In the world of specialty coffee, it’s now fairly routine to encounter descriptions that are both intriguing and precise. Case in point: finalists at the 2021 World Barista Championship distinguished their coffee flavors with creative terms like “cake batter,” “melted chocolate ice cream,” and “banana custard.”

Gary posits that the emergence of these distinctive flavor notes is primarily due to the utilization of rarer coffee species and varietals, coupled with innovative processing methods. On the other hand, Nick attributes this trend to the adventurous palates of the younger generation.

“Younger consumers typically show a willingness to explore unconventional coffee, including the ‘novel’ or ‘wild’ fermented varieties that offer unique and captivating flavors,” he observes. “From my perspective, this openness not only draws newcomers into the world of specialty coffee but also enhances their engagement with it.”

Concurring with Nick, Gary notes: “Based on what I’ve seen, those who are just beginning to explore specialty coffee seem to gravitate towards these novel and intriguing flavors, and they frequently report tasting the specific notes that are advertised on the packaging.”

Considering Age’s Role in Coffee Evaluation Practices

Emerging research underlines that age-related changes in taste perception might affect our ability to discern the nuanced flavors in coffee. This has profound implications for practices like cupping and the subsequent scoring of age affect how you taste coffee.

During their participation in the 2022 Best of Panama Auction, Gary and Nick witnessed firsthand the influence of age on coffee scoring. It’s worth mentioning that the panel consisted entirely of seasoned cuppers and Q-graders.

Despite the calibration efforts, noticeable variance in scoring surfaced. While a minor divergence of one to two points is normal, this event saw gaps of five to six points for certain coffee, which is highly unusual.

Furthermore, a striking development occurred when two judges awarded a perfect score of 100 to a age affect how you taste coffee, a rarity in such contexts.

“From my perspective, the older judges gravitated towards classic Gesha profiles with their floral and subtle notes,” Nick reflects. “Conversely, younger judges seemed to award higher scores to age affect how you taste coffee with more intricate flavors.”

Gary adds that, in his view, variations in the judges’ cupping experience and their cultural backgrounds also played a role in the disparate scoring outcomes.

Revising Cupping Standards to Embrace Diversity

The 2022 Best of Panama auction highlighted potential age influences on cupping evaluations, but both Nick and Gary concur that expertise in cupping remains the crucial determinant.

Gary, drawing from his judging experience, notes a tendency: individuals from Southeast Asia and the Middle East often show a preference for age affect how you taste coffee with fermented, wine-like flavors, while North Americans and Europeans generally lean towards more conventional tastes, reflecting their distinct culinary traditions.

Nick points out the significance of regional market variations in shaping flavor preferences. “Take Santiago in Chile, for instance, where the specialty age affect how you taste coffee scene is more advanced than in Buenos Aires, Argentina. This sophistication translates into a greater appetite for unconventional coffee profiles,” he explains.

Challenging and Refining Cupping Bias

The Specialty Coffee Association (SCA) terms the aforementioned cupping bias as “intersubjectivity”—where cuppers evaluate based on market-specific desirability rather than impartial quality assessment.

To address such biases, the SCA has been developing the age affect how you taste coffee Value Assessment System. This new system aims to eradicate biases, both conscious and subconscious, and to foster a cupping protocol that respects and incorporates a multitude of cultural tastes and culinary backgrounds.

Age undeniably impacts our flavor perception in age affect how you taste coffee, yet it’s evident that other elements, such as experience and cultural nuances, also significantly shape our sensory experiences.

Bias, whether conscious or not, inevitably infiltrates the assessment of coffee’s quality and taste. Nevertheless, with the advent of innovative processing methods and the introduction of novel varieties and species, the range of age affect how you taste coffee flavors is set to expand even further. This evolution underscores the need to refine our evaluation processes to embrace this growing diversity.
