How do beer kegs work

Inside the keg, there’s a long tube of metal extending from the valve to the vessel’s bottom. To get beer out of the keg, gas pressure is applied to the top surface of the liquid, which presses the beer from the bottom of the keg up through that metal tube and out of the valve.

How long does beer last in kegs?

This is especially true for craft beers because different styles of beer last longer than others. A good rule of thumb is that the shelf life for a keg of pasteurized beer is about 90-120 days (or 3-4 months), and unpasteurized draft beer will last about 45-60 days (or 6-8 weeks) when stored at the proper temperature.

How does a keg valve work?

Temperature

Do you need CO2 for a keg?

For the majority of draft beer dispense systems, CO2 is the primary gas used to get the beer out of the keg and into your glass. The pressurized gas from the tank propels the beer through the keg coupler via the beer line. The beer travels up to the faucet tap and dispenses into your waiting glass.

Can a beer keg explode?

It is impossible for a keg to explode under beer pressure. A 120-130 psi rating means it can handle a greater amount of pressure. When the seal fails, it is the seals rather than the chamber itself that fails. At standard pressures, a leak (pinhole or crack) is what we expect from a failure.

Can I leave a keg outside?

Use the outdoors to keep untapped kegs cold
If you live in a cool climate, half the year you can store the keg in your garage or outdoors. However, you will have another problem if temperatures drop below 32 degrees. It is not recommended that a keg be stored below 36 degrees to maintain flavors.
