SCA Cupping Protocol

The SCA Cupping Protocol is the universal language of specialty coffee. Developed by the Specialty Coffee Association (SCA), this standardized sensory analysis method allows coffee professionals—from farmers and exporters to roasters and buyers—to evaluate coffee quality in a consistent, reproducible way. By stripping away the variables of brewing, the protocol isolates the inherent quality of the green coffee, allowing for an objective score that determines its grade and market value.

What is the SCA cupping protocol in practice? It is a rigid, step-by-step procedure. The protocol specifies the exact grind size (coarse), the coffee-to-water ratio (typically 8.25g of coffee per 150ml of water), and the water temperature (93°C or 200°F). The coffee is steeped for four minutes before the 'crust' of grounds on the surface is broken with a spoon, allowing the taster to evaluate the fragrance. After skimming the foam, the coffee is slurped from a spoon to aerate it, which helps the taster perceive the full range of flavor, acidity, body, and aftertaste.

This method is essential for the specialty coffee supply chain. When a buyer in Europe receives a sample from a producer in Colombia, they use the same protocol to ensure they are evaluating the coffee under the same conditions as the producer. This creates a 'Rosetta Stone' for quality, ensuring that a score of 85 points in one country means the same thing as 85 points in another. It is the foundation of the 100-point scoring system used to classify coffee as 'Specialty Grade.'

Beyond just scoring, the protocol is a tool for identifying defects. By cupping multiple samples side-by-side, a professional can quickly spot inconsistencies or processing errors. It is a disciplined, professional practice that requires training and calibration. For the serious coffee enthusiast, understanding the SCA cupping protocol provides a window into how the industry values coffee. It is not just about 'liking' a coffee; it is about systematically analyzing it to understand its quality, potential, and place in the market. In practice, it is the ultimate tool for quality control and trade.
