irn-bru
Originally Iron Brew, this is a Scottish soda that is described as "Scotland's other national drink" after Scotch whisky. Glasgow-based A.G. Barr manufactures the drink, first introduced in 1901. It has long been the most popular soda in Scotland ahead of the likes of Coca-Cola, Pepsi and Fanta and is also sold elsewhere in the United Kingdom. In addition, it can also be found internationally in areas where there is a sizable Scottish community.
