Carbonates are the largest category of soft drinks in the UK, with a market share of 38%, covering products from colas, lemonade and fruit drinks flavoured waters to mixers and shandy.
Low and no calorie drinks make up 45% of the category, with a further 5% being mid calorie.
The factor common to all carbonated drinks is they contain carbon dioxide to make them fizzy. They have been in existence since the late eighteenth century, when Dr Joseph Priestley discovered a means of artificially carbonating water.
The products range from colas, lemonade to fruit drinks, sparkling flavoured water and shandy. Regionally some flavours are more popular than others, e.g. Irn-Bru in Scotland and Vimto in the North West.
