Barr Soft Drinks has made Irn-Bru 1901 a permanent addition to its core range.
The full sugar, sweetener- and caffeine-free variant originally launched as a limited edition in December 2019.
The ‘old and unimproved’ Irn-Bru is made to a handwritten recipe dating from 1901 that lay gathering dust in Barr’s archives for more than 100 years. It is available now in 750ml glass bottles.
Adrian Troy, Marketing Director at Irn-Bru, said: “1901 proved super-popular with fans who really loved the recipe but were disappointed when stock ran dry. Now it’s back for good, so shoppers can enjoy it year-round.”
