Producers

Who grew it.

6 smallholder producers from South Sumatra smallholder cooperative.

Cherries depulped, fermented overnight, then hulled at high moisture in the traditional Sumatran giling basah method before final drying. This is the regional process that gives Sumatran coffees their distinct heavy body and earthy depth.
