What is beer gas station?

A beer gas station, also known as a nitrogen gas station or a mixed gas station, is a facility that dispenses specialty gases for use in draft beer systems. These gases are used to preserve the freshness and quality of the beer by ensuring a consistent pressure and carbonation level within the keg. Beer gas stations typically offer a variety of gas blends, such as nitrogen and carbon dioxide or nitrogen and helium, to meet the specific needs of different types of beers. They also sell equipment and accessories like gas regulators, hoses, and couplers, and provide repair and maintenance services for draft beer systems. Beer gas stations can be found at breweries, bars, restaurants, and other commercial establishments that serve draft beer.
