Processing method
Natural Processing
The oldest way to process coffee — drying the whole cherry so the fruit's sugars soak into the seed.
What is natural processing?
Natural (or dry) processing is how coffee was first prepared, and it's the simplest: the whole cherry is dried in the sun with the fruit still attached, and only once it's brittle is the dried husk removed to free the seed inside.
Because the bean spends weeks marinating inside its own fruit, sugars and fruity, fermentative compounds migrate into the seed. The cup is bigger, sweeter, and wilder than a washed coffee — and a little less predictable, since drying whole cherries evenly is hard work.
Step by step
- Harvest & sort — only fully ripe cherries are picked; underripes and damaged fruit are floated off.
- Drying whole — cherries are spread on raised beds or patios, fruit and all.
- Raking — they're turned by hand many times a day so they dry evenly and don't mould.
- Resting — over 2–6 weeks the cherries shrivel to a dark raisin at ~11% moisture.
- Hulling — at the dry mill the brittle husk is cracked off to reveal the green bean.
What it tastes like
Expect heavy body, low-to-moderate acidity, and intense fruit — blueberry, strawberry, and ripe tropical notes, sometimes with a boozy, wine-like edge. Done well it's lush and jammy; pushed too far it tips into ferment-y or "compost" flavors, which is the line skilled producers walk.
Where you'll find it
Natural processing dominates in dry, sunny climates with limited water. Ethiopia (especially Harrar and many Sidamo/Guji lots), Yemen, and Brazil are the classic homes of the style — and it's enjoyed a global revival as roasters chase those fruit-bomb flavors.
