Keg Carbonation Calculator

Force carbonating beer requires the correct regulator setting. Calculates keg pressure (in PSI) to set the regulator at given temperature and volumes of CO2 when kegging beer.

Carbonation Guidelines by Style
British Style Ales 1.5 - 2.0 volumes
Belgian Ales 1.9 - 2.4 volumes
American Ales and Lager 2.2 - 2.7 volumes
Fruit Lambic 3.0 - 4.5 volumes
Porter, Stout 1.7 - 2.3 volumes
European Lagers 2.2 - 2.7 volumes
Lambic 2.4 - 2.8 volumes
German Wheat Beer 3.3 - 4.5 volumes

Simple Approach: A middle of the road number to shoot for is 2.2 volumes. The pressure regulator on my keg system is set to 8 psi, which at 38 degrees gives about 2.2 volumes of carbonation. With a 3 foot long picnic tap this leads to fairly good pour results. A longer line would help reduce some of the foam but it is manageable. When I fill a pint glass there is about 1" - 1.5" of head. For more information, see our article on how to get a good pour based on line length and pressure.

Notes: Be careful with pressurized gas. Always test your relief valves and do not exceeded manufacturer recommendations!

Keep in mind, the lower the setting on your regulator, the longer your CO2 tank will last (provided there are no leaks). There is nothing worse than over carbonating an otherwise successful batch of beer. Take your time with force carbonation. About a week is all it takes!
