The Process

What is wet-hulling (Giling Basah)?

Wet-hulling is unique to Indonesia. Unlike washed or natural processing, wet-hulled coffee has its parchment removed while the bean is still at high moisture (30-35%), then finishes drying as a naked green bean.

This process developed because of Indonesia's humid climate—traditional drying would take too long and risk mold. The result is a distinctive flavor profile: earthy, herbal, full-bodied, with low acidity. You can't get this cup any other way.

How wet-hulling works

  • 1 Depulp: Cherry skin removed same day as harvest
  • 2 Ferment: Brief fermentation to loosen mucilage
  • 3 Partial dry: Dry to 30-35% moisture in parchment
  • 4 Wet-hull: Remove parchment while still wet
  • 5 Final dry: Finish drying as naked green bean

Strategy

Sumatra as your gateway coffee

Not every customer walks in wanting fruit-forward Ethiopian. Some want "coffee that tastes like coffee"—dark, bold, full-bodied. Sumatra meets them where they are.

Meet customers where they are

Dark roast fans aren't wrong—they just have different preferences. Sumatra gives them specialty quality in a familiar profile. It's a bridge, not a compromise.

Build trust first

Once dark roast customers trust your Sumatra, they're more open to trying your other offerings. You've earned credibility in their preference space.

Expand their palate

Start with Sumatra. Then maybe a medium-roast natural. Eventually, they're drinking light-roast Ethiopian. You've converted a dark roast fan to a coffee explorer.

Flavor Profile

What to expect from Sumatra

Earthy notes

The signature wet-hulled character. Forest floor, mushroom, tobacco—complex earthiness that dark roast fans love.

Full body

Heavy, syrupy mouthfeel. The body that espresso blends often lack on their own.

Low acidity

Muted, soft acids. Comfortable for customers who find bright coffees too aggressive.

Herbal notes

Cedar, herbs, sometimes leather. Complex aromatics that reward attention.

Dark chocolate

Bittersweet chocolate notes, especially in medium-dark roasts. Crowd-pleasing sweetness.

Roast flexibility

Works medium to dark. Darker roasts emphasize body; medium brings out more complexity.

Blending

Sumatra as blend backbone

Many roasters use Sumatra as a foundation in their espresso blends. The full body and low acidity provide a base that other origins can build on—add Central American brightness or African fruit to taste.

Even at 20-30% of a blend, Sumatra adds noticeable body and smoothness. It's the "backbone" that makes espresso feel substantial without dominating the flavor.

Common blend ratios

  • — 20-30%: Adds body without dominating
  • — 40-50%: Noticeable earthy character
  • — 60%+: Sumatra-forward profile

Pair with: Central American for balance, Ethiopian for complexity, Brazilian for chocolate.
