“A shortage of carbon dioxide has hit Britain’s biggest brewers and soft drink makers, disrupting production just as drinkers’  thirst peaks due to a heatwave and a World Cup soccer tournament in which England is doing unusually well.
“Hot weather and a build-up of beer stocks ahead of the World Cup lifted CO2 demand from brewers just as the gas was in short supply due to production shutdowns at chemical factories that produce it as a byproduct.
“The CO2 shortage is also affecting producers of meat and frozen foods, which could put a chill on summer barbecues.”
