If you’re going to have Irn Bru, it’s got to be “1901”. The “standard” Irn Bru isn’t Irn Bru. It’s really Diet Irn Bru. They replaced a large portion of the sugar with artificial sweeteners due to the “sugar tax”. Irn Bru 1901 was released as a “limtied edition” but has now been brought into regular production thanks to how popular the “limited edition” was.
