Carbonation Pressure Calculator

Estimate the keg pressure needed for your target carbonation level.

Guide

Before you start

Keg pressure mostly depends on beer temperature and your target CO₂ level. Colder beer needs less pressure to hold the same fizz.

How this is estimated

The pressure estimate uses beer temperature and the CO₂ level you want in the keg. Colder beer holds CO₂ more easily, so it needs less pressure than warmer beer. Warmer beer, or a higher carbonation target, needs more pressure.

A few notes

This is an estimate. Check your regulator, keg, and line ratings. Serving pressure and carbonation pressure are not always the same.

Use accurate measurements for the best estimate.
