ABSTRACT:
A coffee grinder which has several different automatic grinding capacities is connected to a coffee brewer which has several different automatic brewing capacities by a control that inhibits brewing of all but the corresponding brew capacity following grinding of a quantity of coffee. The grinder is also inhibited from grinding any more coffee until the appropriate brew cycle of the coffee brewer is started. Once the corresponding brewing cycle is selected, the coffee grinder is reset and any grinding capacity may be selected. A calibration mode for the coffee grinder and the coffee brewer is provided wherein the duration of the grinding cycle or brewing cycle, respectively, is set by manually initiating the cycle and then halting of the cycle when the appropriate capacity is reached. The duration of the cycle is then set for subsequent automatic operation.
