The site where the iconic soft drink Irn-Bru was supposedly invented stands as a whimsical testament to Glasgow’s rich history. According to a tongue-in-cheek plaque, attributed to the Glasgow Information and Kultural Identity Taskforce (GlaIKIT), the origins of Irn-Bru date back to 1863 when Robert Barr, the son of a cork-maker from Falkirk, allegedly found himself brewing tea on a rocky outcrop in Glasgow.
The story recounts that Barr accidentally knocked over his kettle, leading the hot water to dissolve some of the rock, resulting in an effervescent, bright orange liquid. Intrigued mixture, Barr tasted it and discovered a unique, slightly metallic flavor. Seizing the opportunity, he acquired the land around the outcrop and began mining what he called his “guid ore,” later transforming it into a health tonic known as Iron Brew. This concoction quickly gained popularity, making Barr a millionaire within a short span.
By 1890, Barr had exhausted his supply of guid ore. Despite extensive efforts to find more, he was unable to locate another source. At that point, he had accumulated enough stock to continue producing Iron Brew (which would be rebranded as Irn-Bru in the 1940s) until 2037. However, after that, his company would face a significant challenge, as production could no longer continue without the sought-after ore.
In 1892, Barr sold the mine to the Caledonian Railway Company, which utilized the area for a new railway line connecting Glasgow’s west end to the city center through a tunnel. Unfortunately, the steam from the train engines mingled with the last remnants of guid ore, resulting in a distinctive taste that did not resonate well with the more discerning citizens of Glasgow’s fashionable west end, leading to its closure shortly after.
The plaque, featuring this eccentric narrative, was put up , known for sharing fanciful tales from Glaswegian history, blending fact with folklore. Whether or not the story of Irn-Bru’s creation is entirely true, it contributes to the character of a city proud of its unique contributions to culture and beverage history.
