When you keg beer, you can make it faster than the bottling process because of CO2 tanks. You use the tanks to carbonate the beer instead of waiting on natural carbonation with bottling. This process is also easier because you don't have to determine the proper carbonation level; it works at any level. At E.C. Kraus, we carry seamless aluminum alloy CO2 tanks in two sizes: 5 lb. and 10 lb. We also offer a CO2 washer to get the right seal with the tank and the regulator.
