Quick answer: Coffee processing removes the fruit from the coffee seed before it's dried and roasted. Washed coffees have the fruit and sticky mucilage removed before drying, often tasting clean and bright. Naturals dry inside the whole cherry, often tasting fruity and full-bodied. Honey coffees have the skin removed but keep some mucilage while drying, landing in between. Wet-hulled coffees, common in Indonesia, tend to be earthy and heavy.
Key takeaways
- Washed: clean, bright, more water-intensive.
- Natural: fruity, sweet, heavy body.
- Honey: sweet and balanced; color grades track mucilage.
- Wet-hulled: earthy, full-bodied, low acidity.
Why processing matters
A coffee bean is the seed of a cherry. Before it can be roasted, the skin, fruit pulp and sticky mucilage have to come off, and the seed has to dry. How and when that happens shapes flavor as much as almost anything else.
Washed (fully washed)
Achilles Coffee Roasters describes the washed process as depulping ripe cherries, removing the mucilage by fermentation or machine, washing, then drying the parchment over days to weeks.
- Typical flavor: clean, bright, clear acidity; fruit and floral notes stand out
- Common in: Kenya, Colombia, Guatemala, Rwanda and many Ethiopian coffees
- Trade-off: traditionally uses more water
Natural (dry)
Whole cherries dry on patios or raised beds for several weeks, turned often, before the dried fruit is hulled away.
- Typical flavor: intense fruit (often berry), high sweetness, heavier body; sometimes winey or fermented notes
- Common in: Ethiopia and Brazil
- Trade-off: uses less water, but drying must be managed carefully to avoid defects
Honey
Honey processing removes the skin but leaves mucilage on the bean during drying. Ozone Coffee explains that producers often grade honeys by color depending on how much mucilage stays on, though the names aren't standardized:
| Grade | Mucilage left (approx.) | Typical cup |
|---|---|---|
| White | 10–20% | Clean, crisp |
| Yellow | 25–50% | Balanced, mild sweetness |
| Gold | 50–75% | Rich, syrupy |
| Red | 75–90% | Fruity, winey |
| Black | 90–100% | Intense, jammy |
Honey processing is especially associated with Costa Rica and Central America. A close cousin, pulped natural, developed in Brazil in the 1970s.
Wet-hulled (giling basah)
Common in Indonesia, especially Sumatra, wet-hulled coffee is hulled while the seed is still moist and then dried again. The result is typically full-bodied, low in acidity, with earthy, herbal or spicy notes.
Experimental processes
Producers increasingly experiment with controlled fermentations, such as anaerobic fermentation in sealed tanks or carbonic maceration. These can create bold, unusual flavors. Treat the label as a clue, then taste.
How to talk about processing at the counter
- Washed: "clean and bright, like a squeeze of citrus"
- Natural: "fruit-forward, sweet, almost jammy"
- Honey: "sweet and round, between the two"
- Wet-hulled: "earthy and heavy, great with milk"

Frequently asked questions
What is the difference between washed and natural coffee?
Washed coffee has the fruit and mucilage removed before drying, which often produces a cleaner, brighter cup. Natural coffee is dried inside the whole cherry, which often adds fruitiness, sweetness and body.
What does honey process mean?
Honey processing removes the cherry skin but leaves some or all of the sticky mucilage on the bean while it dries. It has nothing to do with bee honey; the name refers to the sticky texture.
Does processing affect coffee flavor?
Yes. Processing is one of the biggest influences on flavor after variety, growing conditions and roasting. Washed coffees tend to be clean and bright; naturals tend to be fruity and full-bodied; honeys often sit in between.
