Many people who are just getting into specialty coffee are often baffled by the flavors described on packaging or by baristas, and may even wonder whether they are simply not suited to drinking single-origin coffee. In fact, it is not at all unusual to be unable to taste specific flavors—the purpose of the SCA Flavor Wheel is to provide a reference range, not to require you to identify each item one by one. This article discusses the origins of the flavor wheel, the 2016 revised edition, localization attempts in Taiwan and Indonesia, and whether China needs its own local flavor wheel, helping coffee lovers set aside their anxiety and return to the simple pleasure of drinking coffee.

Many people, upon their first taste of a specialty coffee advertised as "overflowing with floral aromas and bursting with fruit juice," often detect only sourness or bitterness, and cannot help but wonder whether those flavor descriptions truly exist. Starting from the scientific principles of taste and smell, this article explains the origins of coffee flavor—the tongue can only perceive five basic tastes: sweet, sour, bitter, salty, and umami, while the concrete flavors we experience, such as strawberry or citrus, are actually associations produced when aroma compounds are captured by the olfactory sense through the nasal cavity and combined with taste. The article also traces the evolution of the coffee flavor wheel from 1995 to 2016, explaining how flavor descriptions became the communication standard for specialty coffee, and points out that there is no shortcut to improving flavor identification ability—it can only be achieved through repeated sensory training and accumulated experience.

In coffee tasting, "cleanliness" does not refer to whether the coffee liquid looks clear, nor does it mean a single, bland flavor profile. Rather, it means that upon tasting, there are no unpleasant defective flavors, while at the same time the various flavors are clearly distinct and do not interfere with one another. This metric may seem simple, but in reality it places high demands on every stage of coffee—from cultivation, processing, roasting, and brewing. This article will systematically sort out the meaning of cleanliness, analyze how defective flavors and off-flavors are formed, explain the key impact of brewing and extraction on cleanliness, and finally provide brewing suggestions for two Front Street Coffee beans with high cleanliness.

The specialty coffee wave has made more and more people passionate about describing the floral and fruity notes in light-roasted coffee, but when a cup of dark-roasted coffee is placed in front of them, most can only say nuts and chocolate. Is the flavor of dark-roasted coffee really that one-dimensional? In fact, aroma types such as caramel, roasted, nutty, and spicy are all hidden within it—they are simply harder to identify. In this article, Front Street Coffee will guide you through a systematic understanding of where the flavors in bitter dark-roasted coffee come from and how to capture them, while also reminding you to watch out for those unpleasant negative flavors. [more…]

In the process of learning coffee tasting, most people habitually focus their attention on capturing positive flavors such as floral and fruity notes and caramel sweetness, yet often lack the ability to describe unpleasant tastes. However, the key to truly improving one's tasting ability lies precisely in being able to accurately identify and distinguish negative flavors in coffee. This article, from Front Street's tasting perspective, systematically sorts out common defects such as greenness, over-fermentation, and off-flavors, and with the help of specific imagery such as earthy, woody, smoky, rubbery, medicinal, charred, and moldy, helps enthusiasts build a clear cognitive framework for negative flavors, so as to understand a cup of coffee's quality performance more comprehensively. [more…]

When learning coffee tasting, most people focus their energy on describing positive flavors. For example, when describing a cup of coffee, they can rattle off "jasmine, lemon, strawberry, caramel, chocolate," but when they taste something unpleasant, they can only say "burnt bitter, muddy, green and astringent." In fact, to learn coffee tasting, [more…]

The sweet-and-sour taste and aroma of fruity notes are among the most highly regarded flavor characteristics of specialty coffee. These flavors can be broadly grouped into three major categories: stone fruit, citrus, and berries, with different origins often displaying their own distinctive fruity tendencies. African origins are known for their intense fruitiness, while South American origins tend to present more stone fruit aromas. This article will outline the main origins and their representative flavors, and list Front Street Coffee's recommended beans from Kenya, Ethiopia, Costa Rica, Tanzania, Guatemala, Colombia, and other places, to help coffee lovers understand the tasting direction of fruity coffee more clearly.

“How do you taste citrus in coffee?” Quite a few friends say they envy baristas for being able to casually name the specific flavors in coffee. Some friends also say, I can taste that the coffee is acidic, but that’s far from the citrus you’re talking about. Still others say flavors are all just nonsense. Front Street, in its daily online [more…]

When drinking coffee, we often hear the term "cleanliness" — what exactly does it represent? Simply put, cleanliness is the degree of purity perceived by the tongue — from the first sip to the aftertaste, there are no off-flavors or unpleasant mouthfeel, and the flavors are clearly distinguishable. A cup of coffee with high cleanliness often has prominent floral and fruity notes and sugary sweetness, while flavors like earthiness, woodiness, and rubber are rejected by most people. Many factors affect cleanliness, including the quality of the coffee beans themselves, the proportion of defective beans, the processing and roasting stages, and the brewing method. This article, from Front Street Coffee's perspective, explains the meaning of cleanliness and offers practical advice on selecting and brewing pour-over coffee beans with a bright taste. [more…]

The Coffee Taster's Flavor Wheel is an important tool for every coffee enthusiast and professional to understand coffee flavors. From the first edition of the flavor wheel published by the SCAA in 1995 to the comprehensively revamped new flavor wheel in 2016, the two generations differ significantly in structure, classification logic, and sensory description. This article will compare the design concepts and methods of use of the old and new flavor wheels from a professional perspective, analyze the background and significance of the birth of both versions, and help you cup and taste coffee more accurately. When you come to Front Street Coffee, you can see physical displays of both versions of the flavor wheel in the shop, and follow this article to gain a deeper understanding of the evolution of the Coffee Taster's Flavor Wheel.

"This coffee has a rich fruity profile, with notes of citrus, lemon, oolong tea, and jasmine!!!" For someone who has just been introduced to specialty coffee, this might sound unbelievable—how can you taste so many flavors in one cup of coffee! (Are they just making it up?) In this installment of Barista Growth Diary, we'll share a little [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.

Every cup of coffee contains thousands of aromatic compounds, and these substances interweave into a complex and fascinating flavor profile. The coffee flavor wheel, developed through research by the SCAA (Specialty Coffee Association of America) in collaboration with several universities, provides tasters with a systematic descriptive language. This article will guide you through the origins and composition of coffee flavors, explain the meanings of approximately eighty-five flavors across nine major categories on the flavor wheel, and describe how floral, fruity, nutty, cocoa, spice, and fermented flavors form during roasting and processing. At the same time, we will also introduce the flavor characteristics of specific coffees such as Front Street Yirgacheffe, Front Street Geisha, and Front Street Mandheling, helping you more accurately identify and express coffee flavors in daily life.

Fruity coffee fruit flavors often present a natural sweet-and-sour aroma, making them one of the most prized qualities in specialty coffee. They are generally divided into stone fruits (peach, apricot, apple), citrus (orange, lemon, pomelo, sweet orange), and berries (raspberry, strawberry, blackberry, blackcurrant, cherry). Generally speaking, [more…]

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.

People new to specialty coffee are often puzzled: why can others taste citrus, jasmine, oolong tea? Can a cup of coffee really have so many flavors? In fact, the key to identifying coffee flavors lies not in the taste buds, but in the sense of smell. This article will take you from the principles of sensory perception to understand how the taste buds and orthonasal and retronasal olfaction work together, introduce tasting dimensions such as aroma, sweetness, acidity, mouthfeel, flavor, aftertaste, and balance, and offer sensory-training methods that beginners can put into practice—building a flavor memory bank, making good use of the coffee flavor wheel, exercising associative thinking, accumulating through more exchanges, and paying attention to diet and upkeep. The article also combines examples from Front Street Coffee to help you build your own sensory system step by step. [more…]

In coffee shops, you occasionally hear someone make a peculiar sound while drinking coffee—this is actually a tasting method called "slurping." Although it may not sound elegant, it genuinely helps us capture the flavors of coffee more fully. By changing the temperature and form of the coffee as it enters the mouth, slurping atomizes the liquid and accelerates the release of aromas, while also restoring the taste buds' sensitivity at the right temperature, enabling a clearer distinction of flavor layers such as sourness, sweetness, and bitterness. This article uses Front Street Coffee's Sidra beans as an example to walk you through the specific technique and principles of slurping, helping you understand why this seemingly crude method actually lets you get a head start on experiencing the richer, more delicate flavors in coffee.
