                                Introduced in 2016 following the UK sugar tax announcement, IRN-BRU Xtra was designed to deliver extra flavour and a closer taste to the classic full-sugar version, setting it apart from the long-standing Diet (now Sugar Free) variant. This move by AG Barr responded to a shifting market and consumer demand for better-tasting, no-sugar options.
