Natural vs Washed Coffee: How Processing Affects Flavour
Share
The same bean. Two completely different cups.
Imagine two coffees grown on neighbouring farms in Ethiopia. Same altitude. Same variety. Same harvest season. You brew them side by side and they taste nothing alike. One is fruity, almost winey, with notes of blueberry and dark chocolate. The other is clean and bright, with jasmine and citrus coming through clearly.
Same origin. Completely different cups.
The reason isn't the farm or the variety. It's what happens to the coffee cherry after it's picked — the processing method. And it's one of the most important, least talked-about factors in specialty coffee.
What is coffee processing?
When a coffee cherry is harvested, what you actually want is the seed inside — the green bean that will eventually be roasted. But that seed is surrounded by layers: the skin, a dense layer of fruit pulp, a sticky mucilage, and a thin parchment.
Processing is how those layers are removed. And the method used has a profound effect on the flavours that end up in your cup.
There are two main methods: natural and washed. Understanding them is the first step to understanding why specialty coffees taste so different from each other — and how to choose the one that suits you.
Natural process (dry process)
How it works
In natural processing, the whole cherry is dried intact — skin, pulp, mucilage and all. After harvesting, the cherries are spread out on raised drying beds or patios and left to dry in the sun for several weeks, sometimes over a month.
During this time, the fruit ferments slowly around the bean. Sugars and compounds from the pulp migrate into the seed. By the time the cherry is dry, the bean has absorbed a significant amount of that fruity character.
Once fully dried, the outer husk is removed by machine and the green bean is ready to be exported and roasted.
What it tastes like
Natural processed coffees are known for being:
- Fruity and winey — blueberry, strawberry, dark cherry, tropical fruit
- Sweet and full-bodied — the fermentation adds a rounded richness
- Complex and intense — more flavour layers, sometimes bordering on funky
- Lower in acidity — the fruit softens the brightness
If you've ever tasted a coffee and thought "this tastes almost like jam" or "there's something almost boozy about this" — you were almost certainly drinking a natural processed coffee.
Where it's most common
Ethiopia, Brazil and Yemen are the most famous producers of natural coffees. Ethiopia in particular is where the natural process originated, and Ethiopian naturals are considered among the most distinctive coffees in the world.

Washed process (wet process)
How it works
In washed processing, the skin and pulp are removed from the cherry immediately after harvesting, using a depulping machine. What remains is the bean still coated in a thin layer of mucilage.
The beans are then placed in fermentation tanks filled with water, where natural enzymes and microorganisms break down the remaining mucilage over 24 to 72 hours. After fermentation, the beans are washed thoroughly with clean water and then dried — either on raised beds or mechanical dryers.
Because the fruit is removed before drying, the bean has much less contact with the pulp. The result is a very different flavour profile.
What it tastes like
Washed processed coffees are known for being:
- Clean and transparent — the origin characteristics come through without interference
- Bright and acidic — citrus, stone fruit, florals
- Lighter in body — less richness, more clarity
- Consistent and precise — easier to control, which is why specialty roasters love them
If you've tasted a coffee that reminded you of bergamot, jasmine, lemon or peach — that was most likely a washed coffee expressing its terroir with exceptional clarity.
Where it's most common
Colombia, Kenya, Guatemala and Ethiopia (yes, Ethiopia produces both) are the heartlands of washed coffee. Colombian coffees in particular are almost exclusively washed, which is a big part of why they're known for their clean, balanced profile.

Natural vs washed: side by side
| Natural | Washed | |
|---|---|---|
| Fruit removed before drying? | No | Yes |
| Fermentation | Inside the cherry | In water tanks |
| Body | Full, rich | Light, clean |
| Acidity | Lower | Higher |
| Sweetness | Pronounced | Subtle |
| Flavour intensity | Complex, intense | Transparent, precise |
| Typical notes | Blueberry, dark cherry, chocolate | Citrus, jasmine, stone fruit |
| Most common origins | Ethiopia, Brazil, Yemen | Colombia, Kenya, Guatemala |
Is one method better than the other?
No. They're just different — and the right one depends entirely on what you're looking for in a cup.
If you want something bold, fruity and expressive, go natural. If you want something clean, bright and origin-forward, go washed.
Many specialty coffee drinkers find that they go through phases — falling in love with the complexity of naturals, then appreciating the clarity of washed coffees, then circling back. Both reward attention.
The more interesting question isn't which is better, but which is right for the way you brew. Natural coffees tend to shine in brew methods that preserve body, like French Press or AeroPress. Washed coffees often perform beautifully in a V60 or Chemex, where the clean filter lets every nuance come through.
One thing to look for on the bag
Most specialty coffee roasters — including us — include the processing method on the packaging. It's usually listed near the origin and variety information. If it says "natural", "dry process" or "sun-dried", you're looking at a natural. If it says "washed", "wet process" or "fully washed", that's the other camp.
Honey process and pulped natural sit somewhere in between — we'll cover those in a future article.
For now, if you want to taste the difference for yourself: start with a natural Ethiopian and a washed Colombian side by side. It's one of the most eye-opening experiments in specialty coffee.
