Giant CO2 is the homebrewer's best source for CO2, nitrogen, and blended gas in Orange County. We offer beverage-grade gas refills for kegerator tanks at an affordable price. We typically refill 5 lb. CO2 cylinders for mini-kegerators, but welcome tanks of all sizes, from 2.5 lbs to 50 lbs, as long as they are personally owned.

At Giant CO2, we make getting your CO2 tank filled as easy and convenient as possible. When you come in, the first thing we'll do is check that your cylinder is your own personal property. This means that it must either be unbranded (i.e. not stamped with Coke, Pepsi, or other brand) or have a discontinued brand if it was purchased used. We then check the hydro-test date on the neck of the tank. If the date is within the past five years, we'll take your tank back to our CO2 filling station, promptly fill it up, and then return it to you. For those who want beer gas, we'll put your tank on a rolling table for 30 minutes until your gas mixture is fully blended. If your tank's hydro-test date exceeds five years, you can opt to have your tank hydro-tested on site. For recertification, we retest your tank, stamp a new date on it, and then return your tank back to you completely filled. To learn more, click here.
