Have you ever wondered why English beer is always warm and flat? We asked Burke’s Backyard resident scientist, Graeme Quirk, who does a lot of his research in the pub.
Graeme said that it’s just not possible to have warm, fizzy beer. He explained that carbon dioxide (CO2), the gas that makes beer fizzy, is more soluble in colder liquids. As the beer warms up, it loses its ability to hold its CO2 in solution. The CO2 is released into the atmosphere through the bubbles in the beer, and the beer goes flat.
