CO2 is an essential factor to consider when dispensing draft beer and it’s typically the component that has the most questions associated with it. It’s unclear why people are easily intimidated with CO2, but it could be because chemical compounds and subscripts remind them of their high school chemistry class.
Without getting too technical, here are the answers to the most frequently asked CO2 questions:
1. How do I know what pressure my CO2 is set at?
Your regulator, which is the component that connects the tank to the air hose, will have either one or two gauges on it. If it only has one, then that’s the one you’re looking for. If it has two, look for the gauge that shows a range of about 0-60 PSI (pounds per square inch). This will be your regulated pressure gauge. The number the arrow is pointing to on this gauge is how much pressure is being delivered to your keg.
