A Micro-Mill is a tiny low-volume, farm-specific coffee producer who have their lots separate, mill it themselves, gaining total control of the process, and tuning it to yield the best possible flavours (and the best price!) In Costa Rica, farmers usually belonged to large cooperative mills, or simply harvested cherry and sold it to a big mill. Large estates might have complete processing facilities. Now farmers of modest size can craft small micro-lots with complete control on scaled-down equipment.
