CO₂ Solubility Calculator

How Force Carbonation Works: CO₂ dissolves in liquid following Henry's Law: C = H(T) × P
Science: H(T) = H₀ × exp(ΔₛₒₗH × (1/T - 1/T₀)) • Higher pressure = more CO₂ • Lower temperature = better absorption
Practical Use: Find your target carbonation level, set keg pressure accordingly, and wait for equilibrium

Force Carbonation Guide for Homebrewing

Optimal CO₂ levels and pressure settings for different beverages

🍺 Quick Reference: Volumes CO₂ by Style

British Ales: 1.5-2.0 volumes (3.0-4.0 g/L)

German Lagers: 2.4-2.6 volumes (4.8-5.2 g/L)

Belgian Ales: 1.9-2.4 volumes (3.8-4.8 g/L)

American Ales: 2.2-2.7 volumes (4.4-5.4 g/L)

Wheat Beer: 3.3-4.5 volumes (6.6-9.0 g/L)

Cider: 2.2-2.8 volumes (4.4-5.6 g/L)

💡 Force Carbonation Tips:

Quick Method: 30 PSI for 24 hours, then reduce to serving pressure
Slow Method: Set to serving pressure, wait 7-10 days
Temperature Matters: Colder beer absorbs CO₂ faster
Keg Pressure: Use our calculator to find exact PSI for your temperature

❓ Force Carbonation FAQ

How long does force carbonation take?

Quick method (30 PSI): 24-48 hours. Slow method (serving pressure): 7-14 days. Colder temperatures carbonate faster.

What PSI should I use for force carbonating beer?

Depends on temperature and style. At 38°F (3°C): 8-12 PSI for most beers. Use our calculator above to find exact pressure for your temperature.

Can I force carbonate in bottles?

Yes! Use a carbonation cap and CO₂ cartridge. Bottles require higher pressure (20-30 PSI) and longer time than kegs.

Force carbonation vs natural carbonation - which is better?

Force carbonation is faster and more precise. Natural carbonation takes 2-3 weeks but may create different flavor profiles. Both methods produce excellent beer.
