Irn-Bru ( "iron brew") is a Scottish carbonated soft drink, often described as "Scotland's other national drink" (after whisky). It is produced in Westfield, Cumbernauld, North Lanarkshire, by A.G. Barr of Glasgow, since moving out of their Parkhead factory in the mid-1990s, and at a second manufacturing site in Mansfield, Nottinghamshire, England. In addition to being sold throughout the United Kingdom, Barr's Irn-Bru is available throughout the world and can usually be purchased where there is a significant community of people from Scotland. Innovative and sometimes controversial marketing campaigns have kept it as the number one selling soft drink in Scotland, where it competes directly with global brands such as Coca-Cola and Pepsi.
