ABSTRACT:
A plurality of carafes on a coffee machine primarily for restaurant and institution use can be filled selectively with decaffeinated or normal coffee via a distributor between a brewing chamber and the outlets to the carafes. The microprocessor controller operates the device selecting the coffee for delivery to the brewing chamber in response to signals received from the carafes if they are placed at respective stations on the machine so that a decaffeinated carafe at any station will receive only decaf and a normal carafe will receive only normal coffee regardless of the station at which it is placed.
