A drink that couldn't keep its name
Irn-Bru's spelling is a piece of bureaucratic comedy. The drink began life in 1901 as Iron Brew, sold by the Barr family firm. It wasn't brewed, though, and after the Second World War, new food labelling rules meant that a name implying brewing or iron could cause trouble. The solution was to respell it phonetically. Irn-Bru kept the sound, lost the problem, and ended up with one of the most recognisable names in British soft drinks. The company behind it, A.G. Barr, was built by the Barr family, with Robert Barr the figure most often linked to its early days.
What's actually in the bottle
The colour is the first thing anyone notices: a glowing orange that looks like nothing in nature. The flavour is harder to pin down. People have compared it to bubblegum, cream soda, orange, ginger and even fizzy tangerine, and nobody agrees. That's partly because the recipe is a closely guarded secret. The company has long said that only a very small number of people know the full formula, and it is a favourite piece of drinks folklore. The name nods to iron, and the drink does contain a tiny amount of ammonium ferric citrate, around 0.002%. It's hardly a girder.
Made in Scotland from girders
The drink's finest advertising line is "Made in Scotland from girders". It's a cheeky riff on the old iron story, and it fits the brand's deadpan tone perfectly. Barr's campaigns have leaned on humour for decades, from the hangover jokes to the idea that Irn-Bru is "Scotland's other national drink", with whisky taking the first spot. That self-mocking tone has helped it become an identity badge. Scots abroad famously hunt it down, and plenty of visitors take a bottle home as a souvenir.
Ginger, hangovers and Scottish habits
In Scotland, fizzy drinks have long been called "ginger", and Irn-Bru is the most famous ginger of all. It turns up at kids' parties, chip shops, football grounds and the morning after the night before. That last role is the most argued over. Irn-Bru is widely sworn by as a hangover cure, but nobody has proved anything. The reputation sticks anyway, helped by years of advertising that winked at it. The brand has also spread into other things: Irn-Bru-flavoured sweets, chewy bars and ice lollies all exist, and it has been used as a sponsor of Scottish football competitions.
The sugar-tax shake-up
In early 2018, ahead of the UK's soft drinks sugar levy, Barr's reformulated Irn-Bru and cut the sugar by around half. Some fans were furious, and the company soon brought out Irn-Bru 1901, a version with the original sugar content, as a nod to the drink's founding year. It was a rare moment when a fizzy drink's recipe became a national talking point. Sugar-free versions were already well loved, and the reformulation showed how much people cared about the taste of a drink they'd grown up with. And that's the real secret of Irn-Bru: whatever's in it, it has become a piece of everyday Scottish culture.
