Washed coffee - also known as wet-processed coffee - is one of the most widely used processing methods in specialty coffee. The fruit is fully removed from the bean before drying, which produces clean, precise, terroir-driven flavour. If you're looking for a cup that's bright, crisp, and expressive of its origin, washed coffees are a great place to start.
What Is Washed Coffee?
Washed coffee refers to beans that have had the outer skin and sticky mucilage removed before drying. This isolates the green bean from the fruit, allowing its natural characteristics - variety, altitude, terroir - to come through clearly in the cup. Unlike natural process or honey process coffees, which dry with some or all of the fruit attached, washed coffees prioritise precision and clarity.

The Washed Process: Step by Step
- Harvesting & sorting: Ripe cherries are handpicked and placed in water. Unripe or defective cherries float and are removed, ensuring only the best move forward.
- Depulping: The cherries are fed into a depulping machine, which removes the skin and most of the fruit. The beans, still coated in sticky mucilage, move via water channels to the next stage.
- Fermentation: The beans rest in tanks for 8–50 hours depending on local climate and altitude. Natural microbial activity breaks down the mucilage. Some producers use mechanical scrubbers to reduce water usage.
- Washing: After fermentation, the beans are thoroughly rinsed with clean water to remove any remaining mucilage.
- Drying: The clean beans are dried on raised beds, patios, or in mechanical dryers until they reach 10–12% moisture content. Slow, even drying is key - raised beds are preferred for the airflow they provide.
Flavour Profile
Washed coffees tend to be clean, bright, and expressive. Because the fruit plays little role in drying, the bean's intrinsic qualities take centre stage. You can typically expect:
- Bright, well-defined acidity
- Clean, clear flavour with less fermentative complexity
- Floral or citrus notes, depending on origin
- Lighter body compared to natural or honey-processed coffees
- Strong terroir expression - washed coffees are often the best way to understand what a specific origin, farm, or variety tastes like
This makes washed coffees a favourite in the specialty world and on the competition circuit, where clarity and precision are valued highly.
Brew Recommendations
Washed coffees shine in filter brewing methods where clarity and acidity can express themselves fully. We particularly recommend:
- V60 or pour-over - the clean, controlled extraction highlights floral and citrus notes
- Chemex - the paper filter removes oils for an especially crisp cup
- AeroPress - versatile and forgiving; great for washed coffees at any roast level
Environmental Considerations
Traditional washed processing uses a significant amount of water, which can be a challenge in drier growing regions. Modern systems like the Becolsub and Ecomill have dramatically reduced this - cutting water usage by up to 99% in some cases - while also helping to prevent contamination of local water sources. Many of the producers we work with use these or similar systems.
Why It Matters
For roasters and coffee lovers alike, washed coffee offers a transparent window into the bean's origin. It's a consistent, reliable method that rewards producers who invest in quality at every stage - from cherry selection through to controlled drying. If you want to understand what a specific farm, variety, or region really tastes like, start with a washed coffee.
