New research emerging from Brazil is challenging conventional understandings of what constitutes "strong" coffee, revealing that the term is far from a universally defined sensory characteristic. Instead, it is deeply intertwined with cultural context, individual perception, and a complex interplay of sensory cues that can even lead to contradictory interpretations. This qualitative study, published in the May issue of the Journal of Sensory Studies, involved 35 in-depth interviews with Brazilian coffee consumers in the cities of Campinas and Recife. The findings suggest that when consumers express a desire for "strong coffee," or "café forte" in Portuguese, they may be referring to a spectrum of qualities, including bitterness, dark color, roasted aroma, or even the caffeine-induced stimulation, all filtered through a unique cultural lens.
The research team, affiliated with the esteemed University of Campinas, employed "social representations theory" as a framework. This theoretical approach is crucial for understanding how shared cultural ideas and beliefs shape individual perceptions and experiences, in this case, related to coffee consumption. Brazil, a global titan in coffee production and the world’s second-largest coffee-consuming nation by volume, provides a fertile ground for such a study. With coffee present in an astounding 98% of Brazilian households and integral to diverse daily rituals – from morning meals to social gatherings – the beverage holds a profound cultural significance that extends far beyond its economic impact. This deep integration means that the language and symbolism surrounding coffee are deeply embedded within the national psyche, influencing how its attributes are perceived and articulated.
Decoding the Multifaceted Meanings of "Strong Coffee"
The study delved into these nuanced interpretations through a combination of in-depth interviews and a controlled tasting experience. Participants were presented with three distinct filter-brewed coffees: a 100% Arabica designated as "specialty," a 100% Arabica classified as "gourmet," and a "traditional" blend of Arabica and Robusta beans. These coffees were prepared according to standardized recipes to ensure consistency in the brewing process.
During the tasting sessions, several sensory cues emerged as consistently associated with the perception of "strong" coffee. Bitterness, a dark visual hue, a pronounced roasted aroma, and a full-bodied mouthfeel were frequently cited. In a sentence-completion task, where participants were asked to describe strong coffee, common descriptors included "dark," "bitter," "full-bodied," "smoky," or "astringent." Beyond these sensory attributes, a significant portion of participants also linked "strength" to the functional impact of caffeine, describing it as a vital "pick-me-up" that aids in waking up and enhancing focus. This connection highlights the utilitarian aspect of coffee consumption for many Brazilians, where its stimulating properties are as valued as its flavor profile.
However, the research also unveiled a notable ambivalence surrounding the term. The very qualities that one consumer might associate with desirable strength – such as pronounced bitterness or a dark color – could be perceived by another as signs of harshness, over-roasting, or even inferior bean quality. This duality underscores the subjective nature of sensory evaluation and the powerful influence of individual preferences and past experiences.
The Contradictory Landscape of Strength and Weakness
Further illuminating this complexity, the study explored direct opinions on whether participants actually liked strong coffee. The results revealed a near-even split in preferences, with 31.5% of participants expressing a positive affinity for strong coffee, frequently citing the energetic, alert, or stimulating effects. Conversely, a slightly larger group, 34.2%, stated a dislike for strong coffee, associating it with excessive bitterness, poor roasting practices, or the use of lower-quality beans. This divergence of opinion suggests that while the concept of strength is widely recognized, its desirability is far from universal.
The guided tasting experience provided a practical illustration of these differing perspectives. The "specialty" coffee, often characterized by its nuanced flavor profiles and balanced acidity, was frequently perceived by participants as "weak" but pleasant. In this context, qualities like balance and aromatic complexity were prioritized over sheer intensity. In stark contrast, the "traditional" coffee, a blend often associated with robust flavor and a more intense sensory experience, was predominantly described as overly strong, heavily roasted, and unpleasantly bitter. For some, this level of intensity rendered the coffee unenjoyable without the addition of sugar, a common practice in many cultures to temper bitterness. The "gourmet" coffee occupied a middle ground, generally perceived as falling between the more delicate specialty brew and the intensely robust traditional option.
Bridging the Gap: Specialty Industry Language vs. Consumer Perception
This divergence in consumer interpretation has significant implications for the specialty coffee industry. Within specialty coffee circles, "strength" is often approached as a technical and manageable attribute, meticulously controlled through factors like brewing ratios, extraction parameters, and specific flavor intensity metrics. The study, however, posits that the consumer’s understanding of "strength" is imbued with emotional, symbolic, and habitual dimensions that do not always align with this specialized lexicon. This disconnect can lead to miscommunication and unmet expectations throughout the coffee value chain.
The authors of the study emphasize the critical importance of understanding these varied interpretations for the field of sensory science. They note that "consumer vocabulary does not always correspond to standardized sensory descriptors, creating potential gaps between technical evaluation and everyday perception." This is a fundamental challenge for researchers aiming to accurately gauge consumer preferences and product quality.
The implications extend beyond the laboratory and into the marketplace. For producers, roasters, retailers, and foodservice operators, a nuanced understanding of how consumers perceive "strong coffee" is vital. These perceptions directly influence consumer expectations regarding taste, preparation methods, and ultimately, their evaluation of the coffee product. A coffee that is technically brewed to a specific intensity might be perceived as "weak" by one consumer and "harsh" by another, based on their ingrained cultural and personal associations with the term "strong."

Broader Impact and Future Directions
The findings of this Brazilian study offer a valuable contribution to the global discourse on coffee consumption and sensory perception. As the specialty coffee market continues to expand and diversify, a deeper appreciation for cultural nuances in defining desirable coffee attributes becomes increasingly important. The study suggests that marketing efforts and product development within the coffee industry could benefit from acknowledging this subjective landscape, moving beyond purely technical descriptors to embrace the rich, often contradictory, meanings that consumers attach to terms like "strong."
Future research could expand upon these findings by exploring similar semantic variations in other coffee-consuming cultures, potentially revealing a global tapestry of "strong coffee" definitions. Investigating the influence of different brewing methods and bean varietals on these perceptions, within diverse cultural contexts, would also provide a more comprehensive understanding. Furthermore, exploring how the concept of "strength" evolves over time within a given culture, perhaps influenced by trends in specialty coffee or changing consumer habits, would offer further insights.
In essence, this research serves as a potent reminder that the simple request for "strong coffee" is anything but simple. It is a complex expression, laden with personal history, cultural norms, and a dynamic interplay of sensory experiences that researchers and industry professionals alike must strive to understand to truly connect with the global coffee-drinking public. The study underscores the necessity of moving beyond a one-size-fits-all approach to sensory evaluation, recognizing that the perceived strength of a coffee is as much a product of the mind as it is of the bean.
