My son’s supply of Irn Bru It is popularly conceived that the name ‘Irn-Bru’ originated with the re-building of Glasgow Central Station in 1901. When workers from the William Beardmore and Company Steel Works in Glasgow were dying from the large amounts of beer drunk to quench their thirst from the heat of the steel works, an alternative was sought.[by whom?] A local soft drinks manufacturer, A.G. Barr, approached the steel works and a contract was created to provide the workers with this drink. This unnamed drink later went on to be known as ‘Iron Brew’ because of its connections to the steel (and iron) works.
