Carbonation & Priming Sugar — My Brewing Buddy

Brewing Carbonation Calculator

Calculate priming sugar for bottle conditioning or estimate the equilibrium PSI needed to force carbonate a keg with pure CO₂.

Priming Sugar Calculator

Estimate table sugar, corn sugar or dry malt extract needed to reach a target carbonation level.

Beer Volume

Volume Unit

Highest Post-Fermentation Temperature Use the highest temperature reached after active fermentation.

Target Volumes of CO₂

Priming Sugar

Enter the batch details to calculate priming sugar.

Estimate: sugar = (target CO₂ − residual CO₂) × liters of beer × sucrose basis × sugar-type factor.

Force Carbonation Pressure

Estimate the pure-CO₂ regulator pressure needed to maintain the selected carbonation level at equilibrium.

Current Keg Temperature

Temperature Unit

Target Volumes of CO₂

Altitude in Feet Approximate adjustment: add 1 PSIG per 2,000 feet.

Enter the keg details to calculate equilibrium pressure.

Safety: Confirm that fermentation is complete and final gravity is stable before bottling. Use only bottles, kegs, fermenters, regulators and fittings rated for the expected pressure. Too much fermentable sugar or pressure can cause overcarbonation, severe foaming, container failure or injury. Calculations are estimates; verify ingredient specifications and equipment limits.
