CO2 & Gas Tanks

Kegging beer is very convenient as it allows home brewers to store (and serve) their beer in larger quantities. Unlike bottling beer manually, home brewers can dispense draft beer from their Cornelius keg and kegerators.

To build a kegging system, home brewers need a few extra pieces of equipment and tools. One of the important pieces used in this system is the Carbon dioxide (CO2) tank. Connecting a CO2 tank is necessary to provide carbonation to the beer. It is also used to push the beer out from the Cornelius keg and into your glass.

When buying a CO2 tank, most home brewers often get the five-pound tank because it is easier to transport. But if you need to dispense a lot of beer, opting for a 20-pound tank is a better option. Moreover, choose a tank that is certified for safety purposes. (more info below)
When you first get the CO2 tank, it is often empty. Make sure to take it to a beverage supplier or a fire extinguisher supplier to have it filled with Carbon dioxide. While filling the tank with CO2, its surface will feel cold. Before you connect the regulator to the tank, let it settle for at least 24 hours or until the surface of the tank has returned to room temperature.

When carbonating the beer, connect the tank to the keg and set the regulator to the pressure (PSI) that is appropriate. If you are not sure what volume to use, you can always settle for 2.0 volume of carbon dioxide.

Another option is Nitrogen cylinders. Nitrogen is the gas used when you are dispensing homebrews under high pressure. When using a stout spout you will find that nitro will dispense a perfect creamy head (when combined with the stout spout). Getting your pour just right does takes some experimenting, but 30 - 35 psi seems to work best with most systems.

Carbonation is part art and part science. Here at Ontario Beer Kegs, we provide different models of Carbon dioxide gas tanks that you can use for your kegging system. Our gas tanks can hold different capacities from 2.5 pounds to 20 pounds. Be sure to pick the one that is appropriate for your kegging and dispensing system.
