Abstract: A coffee brewing unit is disclosed which enables a brew cycle to be initiated manually or automatically at a preset time, but which prevents a brew cycle from proceeding if a number of required operating conditions are not implemented. If all operating conditions again become implemented after a brew cycle, once underway, is interrupted, the brew cycle continues on to completion. Visual and audible signals indicate the current status of the brew cycle and/or of the brewing unit itself. An insulated carafe is used as the vessel to receive brewed coffee thereby eliminating the need for a warmer plate. The unit may be mounted under a cabinet to thereby maximize usable countertop space and the brew basket utilizes a dispensing valve which is opened by the carafe when inserted into position but which closes when the carafe is withdrawn.
