How a cherry
becomes a bean.
Long before the roast, before the grind, before the water — the flavour of a coffee is already being decided at the farm. Processing is the second harvest. This is a quiet field guide.
A short definition
Processing is what happens to the coffee cherry between picking and export — how the seed is separated from the fruit, and how long the fruit is allowed to influence it.
Every method is a decision about time, water and oxygen. Producers choose them like a chef chooses fire: to reveal something, or to hold something back.

Origin regions
Kenya · Colombia · Ethiopia (washed)
Cherries are pulped within hours of picking.
Beans ferment in tanks of water for 12–36 hours until the mucilage breaks down.
The lot is rinsed clean, then dried on raised beds or patios.
- Timing
- 12–36 h fermentation · 8–14 d drying
- Risk
- Low. The most predictable method.
- Best for
- Showing the origin and the variety without the veil of the fruit.
Natural
The fruit stays.
Origin regions
Ethiopia · Brazil · Yemen
Whole cherries are laid out to dry with the skin and pulp intact.
They are turned daily on raised beds for two to four weeks.
Only once fully dry are the beans hulled from the shrivelled fruit.
- Timing
- No fermentation tank · 14–28 d drying
- Risk
- Higher. Uneven drying can bring defects.
- Best for
- Coffees where sweetness and fruit are the entire story.
Honey
A measured middle.
Origin regions
Costa Rica · El Salvador · Colombia
Cherries are pulped but the mucilage — sticky, golden — is left on the bean.
The lot dries slowly on beds; more mucilage means darker colour and longer drying.
Sub-styles (white, yellow, red, black) mark how much fruit was kept.
- Timing
- No water fermentation · 10–20 d drying
- Risk
- Moderate. Requires constant turning.
- Best for
- Balance — the sweetness of a natural with the clarity of a washed.
Anaerobic
Fermentation, controlled.
Origin regions
Colombia · Costa Rica · Panamá
Cherries or de-pulped beans are sealed in oxygen-free tanks.
Fermentation runs 40 to 120 hours, temperature and pH watched closely.
The lot is then washed or dried in honey style before final drying.
- Timing
- 40–120 h anaerobic · 10–18 d drying
- Risk
- Precise. Small errors compound.
- Best for
- New flavours you cannot reach through classical methods.
The best way to learn processing is to taste it. Order two coffees from the same origin, prepared differently, and brew them side by side.
