Force Carbonation Calculator

Calculate the CO2 regulator pressure (PSI or bar) to force-carbonate homebrew beer to your target volumes of CO2 at a given serving temperature.

Frequently Asked Questions

What PSI should I set for kegging?

It depends on serving temperature and target carbonation. Colder liquid needs less pressure. The calculator uses the standard carbonation equation to return the right regulator PSI for your numbers.

What is a volume of CO2?

One volume means the dissolved CO2, if released, would equal the liquid volume at standard conditions. Most beers sit between about 2.2 and 2.7 volumes; seltzer is higher.

How long does set-and-forget carbonation take?

At the chart pressure, expect roughly one to two weeks to reach full equilibrium, faster if you rock or shake the keg to speed CO2 absorption.

Why measure liquid temperature, not keg temperature?

Carbonation depends on the temperature of the beverage itself. The keg surface or fridge air can differ, so use the actual liquid temperature for accuracy.
