Abstract: An apparatus that vents atmosphere air and allows for the pressurization of a sealed beverage container with carbon dioxide for the purpose of reducing oxidation and preserving or re-introducing effervescence to the beverage housed within the container. The previously mentioned apparatus can be integrated and/or retrofitted to accommodate the various sizes and shapes of current and future portable beverage containers. For the purpose of this apparatus, “portable beverage container” is defined as having a volume less than or equal to 5 gallons and the apparatus uses external or internally integrated pressure regulated gas sources to pressurize the container.
