Cupping

Cupping is often misunderstood as a simple tasting exercise, but it is fundamentally a diagnostic tool designed to strip away the variables of brewing—such as filter type, pressure, or water chemistry—to reveal the raw potential of the green coffee. The mechanism relies on extreme standardization: a specific grind size, water temperature, and a precise ratio (8.25g of coffee per 150ml of water) are used to ensure that any difference in the cup is attributable to the bean itself, not the preparation. For the producer, cupping is the bridge to the market. When a farmer cups their own harvest alongside a buyer, it creates a shared vocabulary that transcends language barriers, allowing them to identify how specific drying or fermentation techniques directly impact the final score. A common misconception is that cupping is purely about assigning a numerical score. In reality, the most critical function of the cupping table is defect detection. By exposing the coffee to hot water without the interference of paper filters or espresso machines, tasters can identify 'taints' or 'faults'—such as mold, fermentation errors, or chemical contamination—that would otherwise be masked by a roaster’s profile or a consumer’s milk and sugar. While the SCA’s traditional 100-point protocol has long dominated, the industry is shifting toward more comprehensive frameworks like the Coffee Value Assessment, which aims to capture a broader spectrum of data beyond just sensory scores, acknowledging that quality is as much about the producer's labor as it is about the final flavor profile.
