Carbonating in a corny keg: pressure by temperature

Carbonation is measured in volumes of CO2. Lagers and IPAs sit around 2.4–2.6 vol, nitro stouts far lower, German wheat beers up to 3.5 vol.

Quick reference (psi)

Rounded reference values. Hold at set pressure for at least 5–7 days before serving.

Steps

1. Chill the keg to serving temperature.
2. Set the regulator from the table and open the gas.
3. Purge the lid relief 2–3 times to clear headspace oxygen.
4. Wait 5–7 days, pour, and adjust 1 psi at a time.
