Carbonation Calculator
The right pressure for the right fizz
CO₂ volumes tell you how carbonated your beer is. A British bitter might be 1.5 volumes. A German wheat beer pushes 4.0+. If you're kegging, you need to know what PSI to set at your serving temperature . This calculator gives you that number instantly.

forced CO₂Set your target CO₂ volumes and serving temperature to find the regulator pressure for force-carbonating kegs.
How We Calculate It
CO₂ equilibrium pressure depends on temperature. Colder beer absorbs more CO₂ at the same pressure. We use an empirical polynomial fit to the CO₂ solubility curve. Enter your desired volumes and serving temp, and the calculator solves for the pressure needed.
Typical CO₂ Volumes by Style
1.5–2.0: British ales, cask-conditioned
2.2–2.7: American ales, lagers, most styles
2.7–3.5: Belgian ales, saisons
3.5–4.5: German wheat beers, highly carbonated styles
See all the numbers come together in real time.
