The Difference Between Physical and Sensory Coffee Quality

Physical quality describes the green coffee itself: moisture, defects, size, density, color, damage, and foreign matter. Sensory quality describes what the coffee tastes and feels like in the cup.

The two are connected but not identical. A visually clean lot can still taste flat or defective, while a flavorful sample can contain physical inconsistencies that create commercial risk.

Professional buying uses both forms of evaluation.

Buyer takeaway: do not approve a lot from a cup score alone. Combine sensory data with green analysis and make sure both refer to the same commercial lot.
