Irn Bru is famous for having a secret recipe. The recipe has not changed in 108 years. There are only 2 people in the world who know the combination of ingredients, one is Robin Barr, the Chairman of AG BARR who makes Irn Bru and 1 other person, whose identity is unknown.

To this day Robin Barr visits the factory to mix the recipe together once a month, and each time this makes 8,000 litres of the juice. He has said that eventually he will pass the information on to his daughter.

One of life's great mysteries!!
