Force-Carb & Priming Sugar
Calculate the perfect PSI for kegging or priming sugar weight for bottle conditioning — with beer-style presets and CO₂ tank consumption estimates.
Safety: when bottling with priming sugar, do not chill the beer below fermentation temperature. Allow 2–3 weeks at room temperature for full carbonation. Never exceed your equipment's pressure ratings.
1) Method & Inputs
Beer Temperature
Typical force-carb range is 32–45 °F.
Pick a beer style preset below or set a custom value.
1.0–1.5 volNearly flat (cask ale)
1.8–2.2 volLow carbonation (stout, porter)
2.3–2.6 volStandard ale / lager
2.7–3.0 volBelgian / wheat
3.5–4.5 volHighly carbonated (lambic, champagne)

High pressure warning — keep regulator and equipment within their rated PSI.
Target CO₂ above 4.0 volumes can over-carbonate normal bottles. Use thick-walled bottles or a keg.
Beer temperature is outside the typical 32–45 °F force-carb range. Carbonation will be inaccurate or slow.
CO₂ Tank Consumption
Estimated kegs you can carbonate and serve from common tank sizes.
