Use this keg carbonation calculator to turn beer temperature and target carbonation into a practical CO2 regulator setting. Choose a BJCP beer style or enter your own volumes of CO2, then use the result as the starting PSI for a balanced kegging setup.
The number matters, but it is only one part of draft performance. A good pour also depends on cold beer, stable kegerator temperature, clean beer lines, the right line length, and a regulator that can hold pressure without drifting.
Quick keg PSI planning ranges
Most homebrew draft systems land in a familiar range once the beer is cold. These ranges are planning guidance, not a replacement for the calculator above.
- Lower carbonation beer: English ale, stout, porter, and mild often pour well around lower CO2 volumes and gentler serving pressure.
- Balanced everyday beer: pale ale, IPA, amber ale, lager, and many common kegged beers usually sit in the middle of the carbonation range.
- Higher carbonation beer: wheat beer, saison, Belgian-style beer, cider, and sparkling mead may need a higher carbonation target and more pressure at the same temperature.
- Temperature check: use actual beer temperature, not just the kegerator display, because warm beer needs more pressure and foams more easily.
From PSI Setting to a Balanced Draft System
Keg Carbonation Calculator and Draft PSI FAQ
Use this page to match beer temperature, target carbonation level, and regulator pressure before serving from a keg. Balanced draft depends on more than PSI alone: beer line length, line diameter, faucet restriction, temperature stability, and keg condition all affect the pour.
What PSI should I set my kegerator to?
The correct keg PSI depends on beer temperature and desired volumes of CO₂. Many ales pour well around moderate carbonation, while wheat beer, saison, cider, and sparkling styles may need higher carbonation. Use the calculator instead of guessing from a single pressure chart.
Why is my keg beer foamy?
Foam can come from warm beer, overcarbonation, too-short beer line, dirty faucets, pressure imbalance, or leaks. Start by confirming actual beer temperature, target CO₂ volumes, serving pressure, and line balance.
