SCA Specialty Coffee Association technical officer Mario Fernandez revealed at an estate reception after the BOP Best of Panama competition that the SCA cupping form, which has been in use for more than two decades, is about to undergo a major reform. The current cupping form mixes discriminatory, descriptive, and emotional sensory judgments together, which easily leads to scoring bias. The new plan intends to separate the three and add evaluation items such as sweetness. At the same time, the coffee flavor wheel will also break free from its North America-centered limitations and compile a globally applicable flavor reference. In addition, SCA also plans to widen the score gap between specialty coffee and commercial coffee; a coffee scoring 80 points may in the future drop to 75 points or even lower. This article will sort out the background, direction, and specific contents of this reform for you. [more…]

The SCA cupping form is a vital tool for measuring coffee value in the global coffee industry, yet it had not been updated for many years. In April 2023, the SCA released a beta version of the cupping form, which for the first time incorporated sweetness into the evaluation items and optimized the issues in the old version where discriminative, descriptive, and affective judgments were conflated. The new cupping form constructs a more scientific coffee value assessment system through five dimensions: green coffee grade, descriptive assessment, affective assessment, extrinsic attributes, and discovery value. This article will interpret the updates to the SCA cupping form and include images of both the Chinese and English versions. Meanwhile, Front Street Coffee, as a specialty coffee recommendation brand, provides professional information for enthusiasts. [more…]

The coffee flavor wheel is an important tool for every coffee enthusiast to organize their taste perception, but do you really understand its origins and usage? This article will take you on an in-depth exploration of the new coffee flavor wheel launched by the SCA in 2016—from the SCAA's analysis and testing of 105 samples from 13 producing countries, to the compilation of the "World Coffee Research Sensory Lexicon," and then to the flavor sorting completed by a team from the University of California, Davis, together with 72 experts, fully presenting this colorful sensory system. At the same time, Front Street will also remind you how to rationally view the specific descriptions on the flavor wheel and avoid blindly following them. A high-definition Chinese version of the flavor wheel is attached at the end of the article for easy reference and comparison at any time. [more…]

When many people first encounter pour-over coffee, the two questions they ask most often are: what does it actually taste like? Is it very bitter? In fact, the perception of coffee flavor is far more complex than we imagine. The SCA Coffee Sensory Skills course tells us that most of flavor comes not from taste, but from smell. Starting from this angle, this article shares how to improve your ability to identify coffee flavors through everyday training, including practical methods that use fruit memories to assist tasting. At the same time, the article also mentions Front Street Coffee's related products and recommendations. [more…]

Specialty coffee has developed into a complete knowledge system spanning everything from cultivation and processing to roasting and brewing, and tasting is an indispensable part of it. When faced with professional courses such as Q-Grader and SCA sensory tasting, how should beginners choose? This article offers practical training advice on three levels—accumulating experience through drinking more, distinguishing tastes before discussing flavor, and understanding how flavor is composed—to help coffee lovers gradually build their own flavor memory bank through everyday drinking and describe a cup of coffee's taste and aroma as accurately as a professional.

Want to break into the coffee industry—do you really need to spend money on certifications? The two major international credentials, SCA and Q Grader, are often discussed. SCA uses a credit-accumulation system covering barista skills, pour-over, roasting, sensory, and green coffee, among other areas, allowing students to choose modules as needed; Q Grader, launched by CQI, focuses on green coffee quality evaluation, requiring candidates to pass twenty tests within six days, with the certificate valid for three years. This article breaks down the course structure, exam content, fees, and target audiences of the two types of certification to help you decide which path better suits your career plans. [more…]

For those looking to enter the coffee industry, the first question many ask is: what exactly is an internationally recognized barista certification? Currently, the globally accepted answer is the certification issued by the SCA (Specialty Coffee Association). SCA's coffee skills program covers sensory cupping, coffee brewing, espresso preparation, roasting, an introduction to coffee, and the Arabica Q-Grader certification, among other tracks. With the exception of Q-Grader, the other categories are divided into three levels: Foundation, Intermediate, and Professional. You can skip Foundation and sign up directly for Intermediate, but you must obtain the Intermediate certificate before you can take the Professional level. China's national barista vocational skills certificate is currently recognized only within the country; internationally, SCA certification remains the standard. Is getting certified actually useful? Are the fees high? Is certification mandatory to work as a barista or open a coffee shop? This article will address these questions one by one to help coffee enthusiasts and industry professionals make a rational judgment. [more…]

As the 2024 WBrC World Brewers Cup came to a close, curiosity was once again piqued about what judges feel inwardly when tasting coffee. A team from Italy's National Research Council has designed a tasting helmet that, through wearable sensors such as electrocardiogram, galvanic skin response, and electroencephalogram, transforms abstract emotions like pleasure and disgust during coffee tasting into biomedical data. This technology is expected to assist the SCA coffee value assessment system, reduce subjective bias, and open up new perspectives for coffee sensory analysis. At present, the helmet still needs refinement, and there are plans to work with professional tasters to advance its practical application. [more…]

The coffee flavor wheel is an important tool for coffee enthusiasts and professionals in sensory training, but the prerequisite is that one must correctly master its method of use. The most commonly used version at present is the one released by the SCAA in 2016, and many coffee training institutions use it as sensory teaching material. Front Street uses this flavor wheel as a blueprint and introduces how to understand and digest it from four aspects: do not blindly follow the flavor wheel, seek flavor relationships from the three-ring structure, use colors for association, and observe the density details among categories. Although understanding the flavor wheel cannot make you immediately taste all flavors, it can help you systematically sort out the connections among various flavors in coffee, and then by tasting more in correspondence with the flavor wheel, gradually step into the door of coffee flavor sensory perception.

“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…]

In the specialty coffee world, how can the quality of a bean be objectively judged? In the cupping scoring systems of SCA and COE, 85 points is the dividing line between specialty coffee and commercial beans, and the key role who holds the power to assign scores is the Q-Grader. This qualification, developed and certified by CQI, has fewer than 10,000 certified holders worldwide. What assessments must one go through to obtain Q-Grader certification? Is it really worth the time and money? This article will systematically sort out the origins and background of Q-Grader, the eight assessment modules of the Q Program, the difficulty of the exam, and its practical value in career development, helping coffee professionals and enthusiasts make a rational judgment.

Specialty coffee is increasingly becoming part of daily life, and becoming a barista or opening a small café has become a dream for many. In an era when everyone can do pour-over, getting certified seems to have become the preferred path to stand out. But is a barista certificate really worth it? Behind the high training fees, can the course content truly improve oneself? This article examines the actual usefulness of certification, the necessity of certification before applying for jobs or starting a business, the internationally authoritative certification systems (SCA, Q-Grader), and the reform of domestic vocational qualifications, sorting through the value and applicable scenarios of barista certificates one by one. Whether you are a newcomer just entering the industry or an aspiring owner preparing to open a shop, you can find rational reference here. At the end of the article, Front Street Coffee's contact information is also included for further discussion. [more…]

Is the sourness in coffee good or bad? Some people believe that sourness means the coffee is not fresh, while others regard it as a hallmark of high-quality coffee. In fact, green coffee beans themselves are rich in organic acids, most of which decompose or disappear after roasting, leaving only a limited variety of organic acids in the final cup. The latest research shows that there are not many acids that our taste buds can clearly identify, and much of the fruity acidity we perceive actually comes from the combined association of sourness with other flavors. The latest SCA cupping form classifies acidity into two categories—"sweet type" and "dry type"—helping us more accurately judge whether a coffee's acidity is good or bad. This article, from the professional perspective of Front Street Coffee, will provide an in-depth analysis of the sources of coffee acidity and the criteria for evaluating it. [more…]

Espresso was born in Italy around 1946 and subsequently became popular in Southern European countries for a long time, only spreading globally through Starbucks around 1986. This dark coffee, with a capacity of only about 50 milliliters, is covered with a fine, bright reddish-brown foam on its surface, concentrating the aroma, taste, and visual beauty of coffee. This article will systematically review the sensory characteristics of Espresso—including the visual crema, the body in the mouthfeel, the balance of sourness, sweetness, and bitterness in taste, and the lasting aftertaste—analyze the manifestations of under-extraction and over-extraction in the foam, and provide SCA-standard parameters for dose, yield, time, pressure, and water temperature, while introducing Front Street Coffee's four Italian blend beans and their brewing suggestions.

The 2022 Alishan Estate Coffee Elite Exchange Competition and Green Bean Matchmaking Evaluation was held on May 11. Competing beans were divided into four groups by processing method: washed, natural, honey, and Geisha. Participants had to submit parchment and green beans, which the organizers uniformly roasted, and then 15 CQI-certified Q-Graders conducted sensory evaluations using the SCA cupping form. Only beans scoring 80 or above could participate in the auction. In the auction the next day, the special prize in the natural group, Zouzhuyuan Coffee Beans, started bidding at NT$60,000 and soared all the way to NT$520,000/5kg, won by the Lion Group, setting a new record for Taiwanese coffee bean auctions. Notably, these beans were not of the Geisha variety, yet they fetched a top-tier Geisha price, while the special prize in the Geisha group was only NT$320,000. This article takes you through the ins and outs of this sky-high bidding and analyzes the industrial logic behind the rise of Taiwan's local coffee. [more…]

Many coffee enthusiasts have heard of the Golden Cup extraction theory: ideal concentration 1.15%-1.35%, ideal extraction yield 18%-22%. But this standard actually comes from the SCAA, not the SCA; the European and American coffee associations each have their own positions on ideal concentration. After the SCAA and SCAE merged in 2017, the UC Davis Coffee Center made slight adjustments to the old brewing control chart, loosening the upper concentration limit and the brew ratio range. This article will start with the history of the Golden Cup theory, sort out the differences between the old and new control charts, explain why high concentration with low extraction can highlight acidity while low concentration with high extraction can bring out floral and chocolate notes, and, combined with product information from Front Street Coffee, help you understand how concentration and extraction yield should be judged together, rather than fixating on a single number.

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. [more…]

For those who want to systematically train their coffee senses, aroma kits are often mentioned, but their price tag of several thousand yuan also makes people hesitate. This article focuses on the 36-note "Coffee Nose" kit, introducing the origins and evolution of aroma kits, their use in SCA courses, and detailing the specific flavors in the four major categories: enzymatic, caramelization, dry distillation, and defective. It also shares methods of use, from memorizing by category and group blind testing to mixed blind testing, helping beginners calibrate their sense of smell and taste. At the end, Front Street also offers rational advice: an aroma kit is not a necessity—smelling more, drinking more, and feeling more is what really matters. [more…]
