Abstract: A self-contained portable beverage dispensing system is provided which includes a housing having an interior space. A first cooling well is defined in the interior space of the housing for pre-cooling of a beverage within a beverage container, and a second cooling well is defined in the interior space of the housing for cooling the beverage after it leaves the beverage container. A tank mounting structure is disposed within the interior space of the housing for holding a propellant gas-supply tank, which is used to pressurize the beverage container. The system is thus self-contained, and the two separate cooling wells enhance the cooling of the beverage that is being dispensed.
