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…]

When you get an unfamiliar single-origin coffee bean, how do you accurately judge its flavor performance? Cupping is the industry-standard method. Front Street Coffee conducts cupping on every coffee bean it acquires, whether or not it goes on the shelves. This article uses the SCA cupping system as its benchmark and provides a detailed introduction to the equipment and parameters required for cupping, including sample bean processing, grind size calibration, coffee-to-water ratio, water quality and temperature requirements, as well as the operating procedures for dry aroma, wet aroma, breaking the crust, and skimming. After cupping is completed, the pour-over grind size and brewing water temperature must also be determined according to the roast level. Light-roast and medium-roast coffee beans each have different standards for sieve pass-through rate and water temperature selection. [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…]

A discussion in the coffee community about the definition of specialty coffee has sparked three soul-searching questions: How exactly is specialty coffee defined? Must drinks made from specialty beans be sold at high prices? Can specialty beans not be dark-roasted? Some people value single-origin traceability and SCA scores, some care about roasting freshness and flavor complexity, and others firmly believe that price equals justice. But the essence of specialty coffee is not "refined and expensive," but a continuous quality improvement from cultivation, processing, roasting, and brewing to service. Dark roasting is not a cover-up for defects, and light roasting is not a guarantee of specialty quality. If good beans lack reasonable brewing and professional service, they are equally disqualified from being specialty coffee. [more…]
