Force-Carb & Priming Sugar Calculator
Calculate perfect carbonation for kegging (PSI) or bottling (priming sugar).
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.

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.
