So I checked out the Party Pig website:
Seems like just the ticket. Thanks.The package requires no CO2 tanks or cartridges because it uses a self-inflating pressure pouch. As beer is dispensed from the PET plastic bottle through an attached push-button valve, the internal pressure pouch expands and maintains a constant 15-20 pounds per square inch of pressure. This is accomplished by combining citric acid and bicarbonate of soda in a controlled manner to produce CO2 gas, which remains inside the pressure pouch and does not come in contact with the beer.
