Wet-Hulled (Giling Basah)

What is wet-hulling?

Wet-hulling — Giling Basah in Indonesian — is a method found almost nowhere outside Indonesia. The defining move: the protective parchment layer is hulled off while the bean is still damp (roughly 30–50% moisture), rather than waiting until it's fully dry. The bare bean then finishes drying exposed to the air.

It's an adaptation to a wet, humid climate where waiting for a slow, even dry is impractical and farmers need cash quickly. Removing the parchment early speeds drying — but leaves the soft, swollen bean vulnerable, which is exactly what gives wet-hulled coffee its distinctive character and its blue-green, hook-shaped beans.

Step by step

1. Depulp — smallholders pulp cherries at home, often the same day.
2. Brief ferment — seeds rest overnight to loosen mucilage.
3. Partial dry — beans are dried only part-way, to ~30–50% moisture.
4. Hull wet — a collector hulls off the parchment while the bean is still soft and damp.
5. Finish drying — the bare green bean dries the rest of the way in the open air.

What it tastes like

Wet-hulled coffee is heavy-bodied, low-acid, and savory — earthy, cedar, tobacco, herbal, and dark-chocolate notes dominate, with a syrupy mouthfeel. It's the polar opposite of a bright washed African: rich and grounding rather than sparkling.

Where you'll find it

This is the Indonesian signature — Sumatra (Lintong, Mandheling, Gayo), Sulawesi (Toraja), and parts of Flores. If a coffee tastes earthy and full with almost no acidity, wet-hulling is very often why.
