1. Start with the beer temperature
Carbonation pressure is tied to the liquid temperature, not just the room or fridge setting. Let the keg settle cold before using the calculator when possible.
- Measure or estimate the keg temperature
- Avoid using room temperature for chilled beer
- Recheck pressure after major temperature changes
2. Pick a CO2 volume for the pour
A moderate ale might sit near the middle of the range, while spritzy styles need more carbonation. Choose the target first, then let the calculator translate that into PSI.
- Use style range as a starting point
- Lower carbonation for softer cask-like pours
- Higher carbonation for wheat, saison, or sparkling styles
3. Set pressure and give it time
The calculator is for equilibrium carbonation. Set the regulator, keep the keg cold, and allow time for the beer to absorb CO2 before judging the result.
- Use stable serving temperature
- Keep gas connected at the calculated pressure
- Adjust serving line balance if pours foam
