What is the process of removing the coffee cherry's outer layer called?

The process of removing the coffee cherry's outer layer is known as hulling. Hulling specifically refers to the action of removing the outer parchment layer that surrounds the coffee bean after it has been processed. This occurs after the coffee cherries have undergone initial processing methods such as wet or dry processing, where the cherries are first fermented to loosen the outer layers, and then the beans are separated from any remaining fruit and husk through hulling.

This step is crucial in the coffee production process, as it prepares the beans for further drying and eventual roasting. The quality of the hulling process can directly impact the taste and flavor profiles of the final coffee product. Understanding hulling helps appreciate the complexity of coffee processing and the importance of each step in developing the final beverage.
