Made to the unique 1901 recipe this ‘old and unimproved’ IRN-BRU proved incredibly popular when it was first released.
Now, fans can rest easy knowing the 750ml glass bottles of the ginger nectar will be available for them to enjoy year-round – just as it was in 1901.
The authentic 1901 recipe came from a handwritten recipe book, which was stored deep in the IRN-BRU archives for more than 100 years.
Its distinct difference comes from its ingredients - quillaia for a frothy head, sweetened only with sugar and containing no caffeine.
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 people can enjoy it year-round with the first bottles going on shelves today.”
