Abstract
A method and apparatus of filing beverage combines pressurized beverage delivery (rather than gravity feed) with variable pressure control of the beverage flow into the can. By modulating beverage flow and especially beverage pressure, it is possible to fill a can's widget (gas reservoir) with gas with a shorter set of fill steps. In addition, the speed of beverage filling can be dramatically increased compared to small scale systems normally used. Unlike known large scale pressure systems, the beverage bowl may be located beneath the rest of the apparatus and modulated pressure may be used, making for a smaller and more portable unit.
