A device for storing and dispensing carbonated beverages such as beer is provided. The device has a fluid compartment and a propellant compartment which are connected through a pressure control means. The pressure control means delivers propellant from the propellant compartment to the fluid compartment as the beverage is withdrawn therefrom to maintain a desired excess equilibrium pressure of the propellant in the headspace of the fluid compartment. For carbonated beverages, the propellant is preferably relatively pure CO2, and also ensures proper carbonation to the beverage. A method of dispensing a carbonated beverage is also provided.
