A coffee maker contains a siphon tube for discharging hot water from a heated reservoir to a container for coffee grounds. Flow through the siphon tube is initiated by pressurizing the air space in the heated reservoir with an air pump. A siphon flow of hot water through the siphon tube to a coffee grounds container then continues without pressurization. The flow is ended when the desired volume of coffee is brewed.


1. A coffee maker comprising: (a) a heated reservoir for holding a volume of hot water such that the hot water forms a level within the heated reservoir with an air space above the hot water;(b) an inlet to the heated reservoir for adding water;(c) a level controller for maintaining a constant hot water level in the heated reservoir;(d) a first vent line communicating between the air space in the heated reservoir and the atmosphere;(e) a vent valve in the first vent line, the vent valve having a position that is normally open and being movable to a close...
