Washed (also called wet-processed) coffee refers to a method where the outer fruit, called the cherry, is removed from the bean before drying. It is one of the three main processing methods, alongside natural and honey.
How the process works
After picking, ripe cherries are pulped to remove the outer skin and most of the pulp. The remaining beans, still coated in a sticky layer called mucilage, ferment in tanks for 12 to 72 hours. Microorganisms break down the mucilage. The beans are then washed clean with water and laid out on patios or raised beds to dry.
The whole process takes one to two weeks, much shorter than natural processing.
What washed coffee tastes like
Cleaner, brighter, more transparent. Washed coffees emphasize the bean’s intrinsic character: the variety, the soil, the elevation. They tend to have higher perceived acidity, lighter body, and clearer flavor notes. A washed Ethiopian Yirgacheffe will taste of jasmine and citrus with no trace of fermentation.
Where it dominates
Most coffees from Latin America (Colombia, Costa Rica, Guatemala, Kenya, Rwanda) are washed. The infrastructure for wet processing exists at scale, and the climate supports it.
Why washed is the standard
Washed coffees are easier to evaluate, more consistent, and more predictable than naturals. They have been the specialty industry’s reference standard for decades. If a green buyer is sampling a new origin, washed lots are usually the baseline before any experimental processing is considered.
