Abstract
A brewing system (100) includes a brew group (130) having a cylindrical brewing chamber (132), a first actuator (146) attached to an upper piston assembly (140) that is movable to sealingly engage one end of the brewing chamber, a second actuator (156) attached to a lower piston assembly (150) that slidably engages the opposite end of the brewing chamber. The lower piston assembly includes a water supply tube (151) that engages a channel through the piston to supply heated water to the brewing chamber. The upper piston assembly includes a dispensing tube (141) that engages a channel through the piston to accommodate dispensing the brewed liquid. A sliding arm assembly is positioned to remove spent grounds from the brewing assembly. The current embodiment includes a controller (100), hopper (112), water heater (11) and grinder assembly (120). An optional flavoring dispenser may also be provided.
