From the keg to the tap, Carbon Dioxide (CO2) propels your delicious draft beer to its destination—your customer’s glass. But there are two things to keep in mind when you’re setting up your CO2 tank so you can serve beer that is perfectly balanced.
CO2 Beer Pressure Settings
The ideal pressure for CO2 is between 10-15 pounds per square inch (psi) but can vary between temperature and altitude. You may need to adjust your pressure by 1 psi for every 2 degrees temperature or for every 2,000 feet above sea level. Keep in mind that different beer styles will require different psi levels. Wheat, Belgian, and sour beers are poured at higher pressures than ales.
How to Measure Your Draft Beer Pressure?
Use your CO2 gauge on the regulator attached to the top of your gas tank to check your psi levels. This lets you know when you need a new CO2 tank and identify any issues in your beer. Your low-pressure gauge shows the psi level your beer is poured. The high-pressure gauge shows the amount of compressed air remaining in the tank. Additionally, if you aren’t sure if your system is balanced, check to see how long it takes to fill a glass. A well-balanced system should fill a standard pint glass in 8 seconds and a gallon in one minute.
