Keg Carbonation Calculator

Calculate the correct CO2 pressure (PSI) to carbonate your keg based on target carbonation volumes and beer temperature.

How to Use This Calculator

Enter your target CO₂ volumes (beer style guides list typical ranges).
Set beer temperature in °F or °C — colder beer absorbs CO₂ more readily.
Review Required PSI for set-and-forget carbonation and Burst Carbonation PSI if you need it faster.
Use Days to Carbonate to plan ahead before serving day.

How the result changes with Target CO2 Volumes

Target CO2 Volumes: Desired carbonation level in volumes of CO2. American ales ~2.3-2.8, lagers ~2.4-2.8, Belgian ales ~3.0-4.0.
Beer Temperature: Temperature of the beer in the keg. Colder beer absorbs CO2 more easily. Typical keg temp is 36-40°F.
