Moisture lostRoasted-bean moisture is a share of the smaller post-roast weight, so it's rescaled to the original batch weight before subtracting: 11.5% green − (2.4% roasted × (100% − 12.5% weight loss)) = 9.4 percentage points.9.4pp
Share of weight loss9.4pp moisture lost ÷ 12.5% total weight loss = 75%. The rest is CO₂ and other volatiles driven off during roasting, not moisture.75%
