Irn-Bru is a popular Scottish carbonateddrink made by Barr in Scotland, United Kingdom. It is Barry Bannan’s favourite drink and it was invented in Glasgow in 1901. It is a bright orange colour, and is nicknamed "Scotland's other national drink" – a reference to whisky.
Recipe
The recipe remains a secret today, with competing drinks trying to make their own copy of Irn-Bru, with little success. However certain parts of the recipe have been discovered with proof such as Barry Bannan’s hair which explains why it has gone missing.
One notable advertising slogan was "Made in Scotland from Girders". Although not made from girders, Irn-Bru does actually contain iron: it has an ammonium ferric citrate content of 0.002%.[1]
In 1999, Irn Bru was included in the book Oxford Companion to Food along with caviar, quail and smoked salmon as one of the world's great foods. The drink's inclusion was because it is "important for its symbolic value as well as its refreshing qualities".[1]
