What is cupping?

At its heart, cupping is the industry’s primary tool for quality assessment. While it may look like a casual ritual—professionals standing around a table, slurping coffee from spoons—it is a highly disciplined practice. The Specialty Coffee Association (SCA) has established rigorous protocols that dictate everything from the roast level and grind size to the water temperature and the specific diameter of the cupping bowls. This standardization is essential because it removes variables, allowing a buyer in London to taste a sample and understand exactly what a producer in Ethiopia is offering.

The process begins with a light, standard roast, followed by a period of rest. When the coffee is ready, tasters evaluate the dry fragrance, the wet aroma after breaking the crust, and finally the flavor profile as the coffee cools. Each attribute—such as acidity, body, and aftertaste—is scored on a 100-point scale. This scoring system is the gatekeeper of the specialty coffee market; any coffee that achieves a score of 80 or higher is officially classified as 'specialty.'

Beyond simple scoring, cupping is used to detect defects and ensure consistency. By using multiple cups for each sample, tasters can check for uniformity, ensuring that every cup from a specific batch tastes identical. If one cup is 'off,' it signals a potential issue in processing or storage. This level of scrutiny is what separates high-quality specialty coffee from commercial-grade commodities.

For the reader, understanding cupping provides a window into how your favorite beans are selected. When you see a flavor profile on a bag, it is often the result of this exact process. It is a way of translating the complex, subjective experience of taste into a shared, objective language that connects farmers, roasters, and consumers across the globe. In practice, it means that the coffee you enjoy has likely been vetted by experts using these precise, repeatable steps to ensure you are getting the best possible cup.
