Following yesterday's posting, it is time to sober up!
Irn-Bru is famous for its bright orange colour. As of 1999 it contained 0.002% of ammonium ferric citrate, sugar, 32 flavouring agents (including caffeine) and two controversial colourings (E110, E124). It is advertised as having a slight citrus flavour, but many have differing opinions of the exact taste of Irn-Bru.
Irn-Bru was first produced in 1901, under the name Strachan's brew. In 1946, a change in laws required that the word "brew" be removed from the name, as the drink is not technically brewed. The chairman of the company came up with the idea of changing both halves of the name to a phonetic spelling, giving the current Irn-Bru brand. It has long been the most popular soft drink in Scotland. It is also the third best selling soft drink in the UK, after Coca-Cola and Pepsi.
Irn-Bru's advertising slogans used to be "Scotland's other National Drink", referring to whisky, and "Bru'd in Scotland from girders", though the closest one can come to substantiating this claim is the 0.002% ammonium ferric citrate listed in the ingredients!
