Cupping began as a quality control method used in the trade to verify whether coffee beans met standards. After the rise of the specialty coffee movement, it gradually evolved into a scoring system for evaluating coffee. Anything below 80 points is classified as commercial grade, while reaching 80 or above crosses the threshold into specialty coffee—the higher the score, the more outstanding the quality. At present, the two globally recognized authoritative scoring systems come from the SCAA and the COE. This article focuses on the SCAA cupping scoring system, breaking down one by one its eleven scoring dimensions, the required number of sample cups, the division of score ranges, and how defect deductions are calculated, to help readers fully understand how a cup of coffee is quantified into a score.

Cupping is a core method used in the coffee industry to objectively evaluate coffee flavor and quality, and it is also an important part of barista training. This article systematically reviews the significance and operational logic of cupping, and compares in detail three approaches: the Brazilian cupping method, the SCAA standard cupping method, and the pour-over cupping method recommended by Front Street Coffee. The article points out that Brazilian cupping focuses on identifying defects and is a negative evaluation; SCAA cupping emphasizes positive assessment of aroma and flavor; while the cupping method used by Front Street Coffee simulates daily brewing equipment and is closer to actual cafe output. The three methods each have different emphases in roast level, extraction method, and evaluation items, and understanding these differences helps roasters and coffee professionals judge coffee quality more accurately.

Before green coffee beans reach our hands, they often go through many stages, during which defects are almost unavoidable. Some defects are obvious at the green bean stage, yet once roasted they may be cleverly concealed. The SCAA (Specialty Coffee Association of America) has established strict grading standards for specialty Arabica coffee, covering multiple dimensions such as defect types, moisture content, aroma, and bean size. This article will systematically sort out the SCAA's defect classification rules and scoring requirements, explain in detail the causes of various defective beans and their impact on cupping flavor, and help enthusiasts develop a keen eye for identifying specialty coffee. At the same time, the article retains relevant recommendations from the Front Street brand for readers' reference. [more…]

In the world of specialty coffee, the SCAA and COE are two authoritative systems that cannot be overlooked.

Behind every single-origin coffee that captivates us stands a key figure who changed the course of the industry. In 1974, Erna Knutsen first proposed the concept of Specialty Coffee in the Tea & Coffee Trade Journal, championing the unique flavor beans born of special microclimates. She only formally entered the coffee trade at the age of forty, yet with an astonishing taste memory and cupping talent, she rose to fame by buying an entire container of Mandheling in one stroke. Thereafter she founded Knutsen coffee, Ltd, helped establish the Specialty Coffee Association of America, and repeatedly won the industry's highest honors. This article takes you through the complete journey of this godmother of specialty coffee, from her childhood in the Arctic Circle to her retirement at 93, to understand how specialty coffee evolved from a single idea into quantifiable industry standards.

The coffee flavor wheel is an important tool in the specialty coffee tasting system. Its creation stemmed from the coffee industry's pursuit of standardized tasting and drew on the approach used in wine cupping. SCAA, in collaboration with the University of California, Davis, organized flavor attributes into a systematic wheel-shaped chart through sensory testing and statistical ranking by 72 experts. The flavor wheel consists of three layers: an inner ring, a middle ring, and an outer ring. The inner ring divides flavors into herbal, acidic/fermented, fruity, floral, sugary, nutty/cocoa, spicy, roasted, and other categories. Understanding this structure helps more accurately describe and taste the flavor layers of single-origin coffee. Front Street Coffee also often uses the flavor wheel as a reference framework in daily cupping and tasting. [more…]

In coffee roasting, how can we ensure that every batch of beans achieves consistent quality? In addition to relying on cupping to evaluate flavor, we also use the RoAmi roast degree analyzer to record the Agtron caramelization value of the coffee beans, and retain historical data for reference. The RoAmi is essentially a colorimeter, with SCAA's Agtron algorithm embedded inside, capable of calculating the roast value by reading the color data of the bean surface or ground surface. This article will introduce how to use this instrument, the meaning of the Agtron value, and how to calculate the Roast Delta value from the bean color value and ground color value, and interpret the guiding significance of this value for roasting rhythm and flavor performance.
