Coffee Quality, Part 1: The birth of specialty coffee flavours
Dec 8, 2025 · 23m
Summary
Host James Harper explores the history of coffee quality standards, triggered by the SCA’s recent overhaul of the Q grading system. He traces the origins of the 2004 cupping form to pioneers like Erna Knutzen and George Howell, who defined specialty coffee by its distinct flavors, such as sweetness and acidity, in opposition to commodity blends. The episode examines how this American-centric preference became a global industry standard, setting the stage for a deeper critique of whose tastes define "quality."
