A digital control system for a coffee bean grinder, particularly one with a dual hopper, which is conveniently programmable and automatically operable for selecting bean type and grinding with a high degree of accuracy bean quantities ranging from a few ounces (e.g., 3 ounces or less) for brewing a few cups of coffee, to large quantities (e.g., 2 pounds or more) for brewing several gallons of coffee. The invention may be confined entirely to a grinder, or may be incorporated in a brewing system consisting of a brewer and one or more grinder. The invention allows one grinder to accommodate one or more coffee grinders either of the same type or of different types (i.e., a brewer for making multi-cup quantities or urns for making gallon quantities).
