What are the three basic degrees of coffee roasting?

Roasting has three major stages: drying stage, browning stage, production period or roasting period.

  1. Drying stage. The coffee bean has 8–12% humidity. We must dry it before roasting starts. Dry stage typically lasts 4–8 minutes with traditional drum roaster. Typically, the end-of-drying temperature is 320⁰F. Especially with drum roasters, you need to be careful not to burn the beans with too much. The drying stage is also critical for collecting bean energy because the last roasting stage is exothermic (heat producing).
  2. Browning stage. From 320⁰F the coffee starts to smell like toasted bread and hay. in Maillard ‘s reaction, removing sugars and amino acids responds, creating hundreds of distinct known as melanoids. This is the stage when the roast naturally slows down to ensure flavor development – and some roastmasters also want to slow it down. After the browning stage, the coffee starts popping. This is called first crack, and the development stage begins.
  3. Development or roasting stage. At the beginning of production, the reaction is exothermic and the coffee splits. The bean accumulated energy through drying and browning periods, causing the coffee to erupt. Production time is when fragrance compounds start formed. When, at the production point,you don’t slow down the roast, you quickly get smoky coffee and the taste is too strong.
