The wet huller at KBQ Baburrayyan Coop at NCBA Mill

The change to wet hulling from dry processing occurred in Gayo area around 1980. The reason was that they simply could not dry the coffee. Removing the outer skin aided in drying, but prematurely hulling out of parchment (wet-hulling) mean the coffee could dry that much faster. It works for mills to trade in humid coffee, since farmer has to do the labor of pulping and dispose of the byproduct. Aceh, Sumatra
