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.

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
