A coffee mill might mean a coffee grinder, but we usually use the term to refer to a coffee processing facility, either a Wet-Mill or a Dry Mill. A wet mill will be part of the wet-process, where coffee is pulped (peeled), fermented in concrete tanks, and then washed and dried. Then it is ready for the dry mill, which may or may not be at the same location. At the dry mill it is hulled out of the parchment skin that surrounds the green bean, classified by density and size, sometimes by color too, and bagged for export. A wet mill can be called a Washing Station or a Factory (Kenya) or a Beneficio Humido (as opposed to a Benificio Seco for a Dry Mill).
