Washed (Wet) Processing
In washed processing, the outer fruit (pulp and mucilage) is removed from the coffee seed before drying. The cherries are pulped, fermented in water tanks to break down remaining mucilage, washed clean, and then dried on raised beds or patios.
The Process
- 1Pulping:Cherries are run through a pulping machine to remove the outer skin and most of the fruit
- 2Fermentation:Beans ferment in water tanks for 12-72 hours to break down remaining mucilage
- 3Washing:Beans are washed in clean water channels to remove all fermented material
- 4Drying:Clean parchment coffee is dried on raised beds to 10-12% moisture
Flavour Characteristics
Washed Ethiopian coffees are prized for their clarity and brightness. Without fruit sugars fermenting on the bean, the inherent character of the variety and terroir shines through.
Bright, clean, often citrus or malic (apple-like)
Light to medium, tea-like, silky
Floral (jasmine, bergamot), citrus blossom
Clean, lingering, often with lemon or stone fruit
Best examples: Washed Yirgacheffe is the quintessential example, with intense jasmine and bergamot notes. Washed Sidamo tends to show more citrus and stone fruit.
Natural (Dry) Processing
Natural processing is the oldest method, where whole coffee cherries are dried with the fruit still attached to the seed. As the fruit dries and ferments around the bean, sugars and compounds migrate into the seed, creating distinctly fruity, sweet flavours.
The Process
- 1Sorting:Ripe cherries are selected and floated to remove defects and unripe fruit
- 2Spreading:Whole cherries are spread on raised beds in thin layers
- 3Drying & Turning:Cherries are turned regularly for 2-4 weeks until dried to 10-12% moisture
- 4Hulling:Dried fruit husk is mechanically removed to reveal green coffee
Flavour Characteristics
Natural Ethiopian coffees are bold and expressive. The extended contact with fruit creates intense sweetness and complex fruit notes that can range from blueberry jam to tropical fruit cocktail.
Lower, wine-like, sometimes fermented
Medium to full, syrupy, creamy
Berry, tropical fruit, dried fruit, wine
Sweet, lingering, often with chocolate or berry
Best examples: Harrar naturals are legendary for wild, blueberry-forward profiles. Guji naturals often show cleaner fruit with stone fruit and tropical notes.
