The coffee roaster performs one of the most critical and essential steps in creating great gourmet coffee. The roasting process is responsible for developing and bringing out the full flavor of the coffee bean. Coffee roasting requires an expertise that takes time to develop.
Roasting Steps
Roasting is done at temperatures of up to 450F degrees. The coffee roaster determines the level or type of roast by controlling the duration and the temperature during the roasting process.
• Yellow phase – this is the first phase of the roasting process. The coffee beans take on heat until they rise to about 210F to 240F. The outer layer of the beans begins to discolor, turning a distinct yellow or cinnamon color. Steam will start being released from the beans. This release of moisture is the initial drying cycle.
