This handy dandy gadget makes kegged beer portable. Just fill a soda bottle from the keg and attach the Carbonator Cap. Depress the center spring and squeeze out all the air from the bottle. Attach a gray gas disconnect and fill bottle with CO2. The gas pressure will keep the beer carbonated until you open the bottle.

To reduce foaming during filling:

1. have the soda bottle is the same temperature as the beer
2. attach a tube from your faucet that is long enough to reach the bottom of the soda bottle to fill from the bottom of the bottle up
3. shut off gas to keg and purge head pressure in the keg and allow gravity to make the beer flow rather than pressure
