– Washing: After fermentation, the beans are washed to remove any remaining pulp and mucilage.
– Drying: The washed beans are then dried to a moisture level of about 11%, either by sun drying or using machines.
Characteristics of Washed Process Coffee
Coffee processed using the washed method tends to have a cleaner and brighter taste, with more pronounced acidity. The flavor profile is often described as nuanced, with notes of citrus, floral hints, and a lighter body. The washed process is preferred in many parts of the world, especially in Central and South America, for its ability to produce high-quality coffees with distinct flavor profiles.
The Natural Process
The natural process, also known as the dry process, is the oldest method of coffee processing. It involves drying the coffee cherries in their entirety, without removing the skin and pulp.
Steps Involved in the Natural Process
The natural process is relatively straightforward:
– Drying: The coffee cherries are dried in their entirety, either by sun drying or using machines, until they reach a moisture level that allows for easy removal of the dried skin and pulp.
– Hulling: Once dry, the cherries are hulled to remove the dried skin and pulp, leaving just the green coffee bean.
Characteristics of Naturally Processed Coffee
Naturally processed coffees are known for their fruity and floral flavors, with a heavier body and lower acidity compared to washed coffees. The natural process allows the coffee to absorb the flavors of the cherry, resulting in a more complex and often sweeter taste. This method is commonly used in Ethiopia and other parts of Africa, where it is valued for its unique flavor profiles and the potential for very high-quality coffees.
