When you see “natural process” or “washed” on a coffee bag, it refers to how the coffee was processed after harvest — specifically, how the fruit was removed from the bean. This single decision has an enormous impact on what ends up in your cup.
The Washed (or “Wet”) Process
In washed processing, the coffee cherry’s outer skin and most of the fruit pulp is removed mechanically within hours of harvest. The beans then ferment in water tanks (which helps break down remaining pulp), are washed clean, and dried.
The result: the flavor in the cup comes almost entirely from the bean itself, not from the fruit. Washed coffees tend to be cleaner, brighter, and more acidic. They showcase terroir and variety most directly. Ethiopian Yirgacheffe washed coffees are the classic example — complex, floral, vivid.
The Natural (or “Dry”) Process
Natural processing skips the wet stages entirely. Whole coffee cherries are laid out on drying beds and left to dry in the sun — sometimes for weeks — with the fruit still attached to the bean. As they dry, the sugars from the fruit ferment and infuse into the bean.
The result: heavier body, lower acidity, and often intensely fruity — blueberry, strawberry jam, tropical fruit. Ethiopian Sidama naturals and Brazilian naturals are good examples. The risk is inconsistency: if drying isn’t managed carefully, fermentation can go wrong and produce unpleasant off-flavors.
Honey Process: The Middle Ground
Honey processing (developed in Costa Rica, popular in Central America) removes the skin but leaves varying amounts of the fruit’s mucilage (the sticky layer) on the bean during drying. “Yellow honey” has minimal mucilage; “black honey” has the most, and behaves more like a natural process.
The cup profile sits between washed and natural: more body than washed, more clarity than natural. The SCA has published extensively on how processing method affects sensory attributes.
Which to Choose?
If you want clean, bright, nuanced flavors — seek washed coffees. If you want bold, fruity, complex sweetness — look for naturals. If you want balance — try honey processed. Try the same origin in different processing methods when you can; the contrast is illuminating.
