Rests green coffee in empty whisky, rum or wine barrels for weeks before roasting so the porous beans pick up wood and spirit aromas.
Barrel-aged green coffee is held in empty barrels that previously held whisky, bourbon, rum or wine, so the porous beans pick up wood and spirit aromas before roasting. One roaster guide gives about two to three weeks. Too little time transfers little flavor, too much can mask the bean, and every barrel behaves differently.
