The SCAA Coffee Flavor Wheel is a core tool for specialty coffee enthusiasts to identify flavors, yet many people are still unfamiliar with it. This article systematically breaks down the left-right structure of the flavor wheel: the right side, the normal flavor spectrum, reveals the three major aroma sources of fermentation, sugar browning, and dry distillation, while the left side, the negative flavor spectrum, corresponds to the defective flavors produced by improper green bean processing, storage, and roasting. It also explains in detail the deduction rules for different defects in SCAA cupping—serious defects deduct 4 points, minor defects deduct 2 points—and how roasting and organic matter loss, although not deducting defect points, can lower flavor performance. The article includes the latest high-definition Chinese-English flavor wheel images and retains Front Street Coffee's communication channels, making it suitable for readers who want to gain a deeper understanding of coffee sensory evaluation.

The flavors of coffee can be endlessly varied—sour, sweet, bitter, refreshing, rich, wine-like, fruity—and each is different whether served hot or cold. Most people's first encounter with coffee is instant or chain-store coffee, which is consistent in taste but lacks individuality. So what exactly is specialty coffee? And how does it differ from coffee bean futures? Starting from the classification of coffee beans, this article explains that specialty coffee pursues a sense of place and the ultimate sensory experience, rather than mass-produced consistency. Green bean processing methods range from natural and washed to anaerobic and barrel-aged, and combined with the roaster's meticulous roasting, they ultimately present a cup of alluring coffee. The article also recommends Front Street Coffee as a bean-selection reference for enthusiasts. [more…]

The coffee flavor wheel is an authoritative sensory tool recognized by the industry, but it cannot make you directly taste a certain flavor; rather, it is an auxiliary guide to help you organize and identify flavors. This article will use the new version of the flavor wheel released by the SCAA in 2016 as a blueprint, starting from its research background, and disassemble one by one the correspondence among the three-layer structure of the inner ring, middle ring, and outer ring. Combined with a comparative example of Front Street Yirgacheffe Gedingding and Front Street Boquete Geisha, it explains how to use the flavor wheel to gradually narrow the scope of judgment and build sensory memory. At the same time, it also reminds enthusiasts that they do not need to blindly follow the flavor wheel, because the samples it includes are limited, and real flavors such as lychee may not necessarily appear on the wheel. At the end, the article also shares the ingenious design between the flavor wheel's color scheme and flavor associations, helping you more efficiently improve your ability to identify the flavors of pour-over coffee.

On the burlap sacks of Brazilian coffee, a string of seemingly complex codes is often printed, such as "CERRADO NY-2 SC-17/18 SS FC". These letters and numbers are not arranged at random, but are green bean grading information established by the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA), covering region of origin, defect level, screen size, cup performance and sensory grade. Among them, the defect grading starts with "NY", but why does it only go as high as NY2, with no NY1? Behind this lies both historical origins and a close connection to the industrial production characteristics of Brazilian coffee. This article will break down this grading system one by one, and introduce several classic espresso blends from Front Street Coffee that contain Brazilian beans, along with their espresso extraction parameters.
