A twin brewer system ( 30 ) with a pair of brewers ( 30 A, 30 B) each with a controller ( 158 ) for controlling the application of electrical power to a hot water heater, disables the application of electrical power to the heater ( 154 ) of one brewer ( 30 A, 30 B) in response to actuation of a start brew switch of the one brewer ( 30 A, 30 B) while electrical power is being applied to the heater ( 154 ) of the other brewer ( 30 A, 30 B). The controllers also respond to a hot water quantity sensor ( 164, 168 ) and a responsive delay circuit for disabling dispensing of hot water in response to actuation of the brew start switch ( 50 ) until a sufficient quantity of hot water is in a hot water dispenser tank ( 152 ) needed for the brew cycle. Indication lamps indicate when the brew cycle is being delayed and when brewing is not being performed. Actuation of a single emergency stop switch ( 138 ) stops hot water dispensing of both brewers ( 30 A, 30 B).
