What’s “Washed coffee”?

[Ref Freeman, James. The Blue Bottle Craft of Coffee (p. 17)]

Washed Coffee is also known as “wet processing

removes the outer skin → soaked in water (fermentation) → rinsed and washed → dry

 

The basic process is that the cherries are sent through a pulping machine, which removes the outer skin, leaving the sticky mucilage, or pulp, still clinging to the beans.

The beans are then soaked in water. Then, the beans are allowed to ferment for a period of time that  ranges from hours to a day or two, during which period of time the pulp falls off.

After fermentation, the beans are rinsed and washed before they are allowed to dry (either sun or mechanical dryer).

Kenya-style processing is similar to wet processing, but the period of fermentation is a bit longer. As a result, beans treated by Kenya-style processing tend to have high acidity and elegance
