Freshly roasted coffee beans contain a large amount of carbon dioxide, and this gas interferes with the extraction of flavor compounds by hot water, so it is necessary to reduce the gas content inside the beans through resting or degassing. Resting lets the beans release gas naturally and waits for them to enter their peak flavor window; degassing, on the other hand, temporarily accelerates gas release before brewing so that overly fresh beans can be used as soon as possible. Both serve the same purpose but differ in the time required and the method of operation. The resting period is related to the roast level, and dark-roasted beans actually need longer. This article explains in detail the difference between resting and degassing, the meaning of the peak flavor window, and includes practical advice from Front Street. [more…]
