Abstract: A receptacle for storing, pressurizing, and dispensing packaged beverages. The receptacle includes an airtight chamber with a removable lid, wherein the joint between the lid and the chamber is also airtight. A gas valve allows for the inflow and outflow of gas, and a tap port and tap stem allow the beverage to be dispensed without breaking the seal of the chamber. A pressure relief valve allows for more rapid depressurization. The chamber can be used at high and low pressures, such as a partial vacuum, to prevent oxidation of a number of open beverages, such as beers, wines, and sodas. A pressure gauge port coupled with an optional pressure gauge allows a user to verify the appropriate pressure for the type of beverage being preserved. The gas valve may be disposed on a base of the receptacle, as may the pressure relief and/or the pressure gauge port.
