Roasting is a process controlled by a person known as the “Master Roaster.” Coffee beans are roasted in a large cylinder-shaped drum that rotates to keep the beans moving. Heat is applied to the outside of the drum. If the beans are roasted too long, many of the compounds that provide the flavor are roasted off, however if the beans aren’t roasted long enough, the flavors will not develop properly.
When the ideal roast temperature is achieved, the coffee beans undergo a series of reactions. They expand and develop numerous flavor and aroma qualities. Over 800 compounds found in the beans contribute to their flavor and aroma. The roasting process brings out these flavors and aromas as it forces the moisture from the beans. The beans are then quickly released from the roaster and cooled. |
