How many kegs will a 2.6 kg CO2 tank last?

Answered by Stephen Mosley

The number of kegs that a 2.6 kg CO2 tank will last depends on various factors, such as the size of the kegs, the desired level of carbonation, and the efficiency of your carbonation system. However, I can provide a general estimate based on common usage.

For homebrewers who are carbonating and dispensing their own beer, a 2.6 kg CO2 tank can typically carbonate and dispense around 200 liters of beer. This estimate is based on using 19-liter kegs, also known as Cornelius kegs or “corny” kegs. These kegs are commonly used by homebrewers due to their convenient size and ease of use.

To carbonate a keg, you typically need to apply a certain amount of CO2 pressure over a period of time. The exact pressure and duration depend on the desired level of carbonation and the temperature of the beer. Once the beer is carbonated, you can use the CO2 tank to dispense the beer from the keg.

Assuming you are using a 2.6 kg CO2 tank, which is equivalent to 5.7 lbs, and each keg holds 19 liters of beer, you should be able to carbonate and dispense approximately 10 kegs before running out of CO2. This estimate assumes that you have an efficient carbonation system and do not experience any significant wastage of CO2.

It’s important to note that this estimate may vary depending on your specific setup and usage. If you are using larger kegs, such as 50-liter kegs commonly used in commercial settings, the number of kegs you can carbonate and dispense with a 2.6 kg CO2 tank will likely be lower. In such cases, you may be able to carbonate and dispense around 8 kegs, assuming a similar level of efficiency and no significant wastage.

Additionally, factors such as the frequency of beer dispensing, the amount of time the CO2 tank is in use, and the temperature at which the beer is stored can also impact the lifespan of a CO2 tank. It’s always a good idea to have a backup CO2 tank on hand to avoid running out during a brewing session or event.

A 2.6 kg CO2 tank should generally allow you to carbonate and dispense approximately 200 liters of beer or around 10 x 19-liter kegs in a homebrewing setup. If you are using larger commercial kegs, the estimate may be lower, around 400 liters or 8 x 50-liter kegs when dispensing pre-carbonated commercial beer. However, it’s important to consider various factors and monitor your CO2 usage to ensure you have an adequate supply for your specific needs.
