Everything You Need To Know About C02 Tanks For Homebrewing

After a while, scrubbing out bottles and going through the capping process becomes exhausting. Kegging beer at home is a whole lot simpler. Sure, there’s an initial investment for the kegging system that’s pricier than a handful of bottles, but pouring a glass of your homebrew from a tap is more than worth it. Not to mention how easy it is to share samples with friends and family.

If you’re going to keg your beer, then you’ll need a regulator, hoses and, of course, a C02 tank. The C02 will also carbonate your beer, so it’s definitely important. But most people haven’t dealt with C02 tanks before, let alone had to refill one, so you might have some questions.


What Size C02 Tank Should I Get?

The most common size for C02 tanks is five pounds and should last for a decent amount of time, depending on how many kegs you’re planning to go through. If you think you’ll be using the C02 tank often, then you can always purchase a larger tank.

Another consideration is where you’ll be placing your tank. Smaller sized C02 tanks are preferable if you want to be able to move the tank and store it while it’s not in use. With smaller tanks, it’s also easier to have a spare tank on hand should one run out. The benefit of larger tanks (20 pounds), is that you don’t have to refill them as often.


Why Do I Need a Regulator?

The regulator tells you the pressure of your C02 tank. It will either have one or two gauges. If it only has one, then that’s the regulated pressure gauge. But if it has two, then one of the gauges is that regulated pressure gauge and the other is a high pressure gauge. The high pressure gauge isn’t necessary, but it can be helpful because it tells you how much C02 is left in the tank, so you aren’t caught off guard when it runs out.


What are the Safety Concerns with a C02 Tank?

Compressed gas tanks can dangerous, so you should always exercise caution and follow safety guidelines with your C02 tank. C02 tanks should remain upright and kept away from sources of heat. You don’t want heat to increase the pressure inside the tank. All C02 tanks should be tested every five years at a certified hydro-test facility to ensure the integrity of the tank.

If your keg is located in a contained space and it becomes difficult to breathe or your head starts to hurt, close the main valve on your C02 tank and ventilate the room. These can be signs of a dangerous concentration of C02 resulting from a leak.
