coffee roasting
Heating green beans
Coffee roasting is the process of heating green coffee beans to develop their flavor, aroma, and color.
The beans are roasted at high temperatures until they reach the desired darkness—from light roasts that preserve origin flavors to dark roasts with bolder, more bitter profiles.
Roasting transforms raw, grassy-tasting beans into the brown, fragrant product ready for brewing.
