Indonesian Coffee Processing Methods (Washed vs Honey vs Natural vs Wet-Hulled)
If you’ve ever wondered why two coffees from the same country can taste completely different, the answer is often processing.
Processing is the method used to remove the coffee fruit from the bean and dry it. It affects sweetness, clarity, body, and even aroma.
Here’s a simple guide to the four processing styles you’ll see most often in Indonesian coffee.
1) Washed process (clean and defined)
What it is: The fruit is removed early, and the bean is washed before drying.
What it tastes like:
· Cleaner flavour separation
· More “crisp” finish
· Often lighter body than other methods
Best for: people who like clarity and a tidy finish.
2) Honey process (sweet, aromatic, and crowd-pleasing)
What it is: Some sticky fruit layer (mucilage) is left on during drying.
What it tastes like:
· More sweetness
· More aroma
· Often “juicy” without being sour
Best for: people who want sweetness + fragrance.
3) Natural process (fruit-forward and bold)
What it is: The bean dries inside the whole fruit.
What it tastes like:
· Big sweetness
· Fruitier flavours
· Heavier, more “funky” character (depending on lot)
Best for: adventurous drinkers and filter lovers.
4) Wet-hulled / Giling Basah (classic Indonesian depth)
What it is: A traditional Indonesian method where parchment is removed while the bean is still moist, then dried again.
What it tastes like:
· Heavier body
· Deep, earthy-sweet notes
· Lower perceived acidity
Best for: people who love classic Indonesian “bold” flavour.

A simple tip to get more sweetness from any process
If your coffee tastes flat, try one change:
· Grind slightly finer (if it tastes weak)
· Grind slightly coarser (if it tastes bitter)
Small adjustments make a big difference.
