cognitivedissonance Irn-Bru is known for its bright orange colour. As of 1999 it contained 0.002% of ammonium ferric citrate, sugar, 32 flavouring agents (including caffeine—though caffeine is not listed as an ingredient on the Australian labelling—and quinine) and two controversial colourings (E110, E124). On 27 January 2010, A.G. Barr agreed to a Food Standards Agency voluntary ban on these two colourings although no date has been set for their replacement. The beverage is advertised as having a slight citrus flavour.
