A modular beverage-dispensing assembly comprising: a housing; a compressed gas tank mounted to the housing; a plurality of discrete beverage containers (212, 214) supported on the housing; and a multipath gas valve downstream from the compressed gas tank in selective upstream fluid communication with the plurality of discrete beverage containers (212, 214) to selectively direct a compressed gas from the compressed gas tank to one beverage container of the plurality of discrete beverage containers (212, 214); characterized in that the modular beverage-dispensing assembly further comprises a multipath liquid valve in selective downstream fluid communication with each beverage container of the plurality of discrete beverage containers (212, 214) to selectively direct a liquid from one beverage container of the plurality of discrete beverage containers (212, 214); and further comprises an outlet nozzle downstream from the multipath liquid valve to dispense a liquid received therefrom; the positions of the multipath liquid valve being associated with or correspond to the positions of multipath gas valve; the modular beverage-dispensing assembly further comprises a pressure-release valve positioned in fluid communication between the multipath gas valve and one beverage container of the plurality of discrete beverage containers (212, 214); the modular beverage-dispensing assembly further comprises a user interface attached to the housing and an assembly controller operably coupled to the user interface and the pressure-release valve, wherein the assembly controller being configured to initiate a dispensing operation comprises: receiving a beverage-output signal from the user interface, determining a non-dispensing state subsequent to receiving the beverage-output signal, and actuating the pressure-release valve to open a ventilation path between the pressure-release valve and an ambient environment in response to determining the non-dispensing state. a housing;
