Parchment (Parche)

Parchment (pergamino in Spanish, parche locally) is the thin cellulosic husk that envelops the green coffee bean after depulping. During wet processing, the parchment-covered bean dries to 10-12% moisture before being hulled and milled to reveal the green bean. Parchment provides protection during drying and storage. In wet-hulled Indonesian processing (Giling Basah), parchment is removed at high moisture (25-30%), distinguishing Sumatran profiles from other washed coffees.
