The Science of Consistency in Coffee QC
Real talk: Consistency in coffee quality control isn’t about guesswork—it’s about precision. A colorimeter isn’t just a gadget; it’s a revelation. It exposes how moisture content can mask the truth. A 10% moisture bean and a 12% one might share the same color, but their weight loss tells a different story. This is why relying on visuals alone is a trap. Roast speed is another wildcard. Fast roasts lose less weight for the same color, while slow roasts burn more. It’s not about time but energy transfer. Development time ratio (DTR) compounds this chaos.
