The way a coffee is processed after harvest is one of the biggest determinants of what ends up in your cup. Here's a clear breakdown of the three main methods — and what they mean for flavour.
Why Processing Matters
After coffee cherries are picked, the fruit must be removed from the seed (the bean) before it can be dried and roasted. How that removal happens — and when — defines the processing method. Each approach leaves a different flavour fingerprint.
Washed (Fully Washed)
The fruit is removed from the bean immediately after harvest, then the bean is fermented in water to remove the remaining mucilage (the sticky layer beneath the skin), and finally dried.
Result: A clean, bright, transparent cup. The terroir of the bean shines through without interference from the fruit. Acidity is pronounced and precise.
Best for: Coffees where origin character is the point — Kenyan AA, Ethiopian Yirgacheffe, Colombian washed lots.
SOLO example: Hongera Kent AA — blackcurrant, red grapefruit, syrupy finish.
Natural (Dry Process)
The whole cherry — fruit and all — is dried in the sun for weeks before the fruit is removed. The bean absorbs sugars and flavours from the drying fruit throughout the process.
Result: A fruit-forward, full-bodied, wine-like cup. Higher sweetness, lower acidity, more fermentation complexity. Can be polarising — at its best, extraordinary; at its worst, overfermented.
Best for: Ethiopian naturals, Brazilian lots, experimental processing.
SOLO example: Nyala Guji Heirloom — jasmine, stone fruit, wine-like body.
Honey Process
A middle path. The skin is removed but some or all of the mucilage is left on the bean during drying. The amount left determines the “colour” — Yellow Honey (less), Red Honey, Black Honey (most).
Result: A balance between the clarity of washed and the sweetness of natural. Smooth body, natural sweetness, moderate acidity.
Best for: Producers who want complexity without the fermentation risk of naturals.
SOLO example: Geisha do Brasil by Danilo Barbosa — jasmine, honey, papaya, silky texture.
Which Should You Choose?
- New to specialty coffee? Start with a honey process — it's the most approachable.
- Want to understand terroir? Go washed.
- Want an experience? Go natural.
