Definition: Beer gas is a blend of carbon dioxide and nitrogen used in draught systems. The presence of nitrogen results in smaller bubbles than carbon dioxide alone. This produces beer with a denser head and a creamier mouthfeel. Beer gas is popular with darker styles of beer such as stout. Beers served with beer gas instead of carbon dioxide alone are sometimes called nitro.
Also Known As: nitro
Examples:
Max enjoys Guinness from a bottle with regular carbonation but he prefers it served on draught with beer gas.
