The Core Question: Is Irn-Bru Sugar-Free?
No, the classic, regular Irn-Bru is not sugar-free, but its sugar content was significantly lowered in 2018. However, the manufacturer A.G. Barr offers multiple sugar-free alternatives to cater to different tastes and dietary needs. The confusion often arises because the brand offers several variants, including 'IRN-BRU Sugar Free,' 'IRN-BRU Xtra,' and the full-sugar 'IRN-BRU 1901,' which uses the original 1901 recipe. To make an informed choice, it is essential to understand the differences between these products.
The 2018 Reformulation and Its Impact
In response to the UK's sugar tax on soft drinks, A.G. Barr reformulated the recipe for regular Irn-Bru in January 2018. Before this change, the drink contained over 10 grams of sugar per 100ml. The new recipe cut the sugar content to just 4.7 grams per 100ml by blending sugar with low-calorie sweeteners, including acesulfame K and aspartame. This change allowed Irn-Bru to avoid the tax, but it sparked a backlash from loyal customers who claimed the taste was different. A campaign titled 'Save Real Irn-Bru' emerged, and some fans even hoarded cans of the old recipe. The taste difference, while debated, was most noticeable to those accustomed to the full-sugar version.
The True Zero-Sugar Options
For those seeking a genuine zero-sugar Irn-Bru experience, there are two main options:
- IRN-BRU Sugar Free: This version is the longest-standing diet variant, launched as 'Low Calorie Irn-Bru' in 1980 and later rebranded. As the name suggests, it contains zero sugar and negligible calories. The taste is achieved using sweeteners such as acesulfame K and aspartame.
- IRN-BRU Xtra: Launched in 2016, Irn-Bru Xtra is another zero-sugar option, but it is formulated to have a bolder flavor profile that some users claim is closer to the pre-2018 full-sugar original. It also uses sweeteners and is specifically marketed for those who want a sugar-free alternative without compromising on the iconic taste.

The Difference Between Sugar-Free and Xtra
Many customers wonder what distinguishes 'IRN-BRU Sugar Free' from 'IRN-BRU Xtra,' as both are sugarless. The difference lies primarily in the flavor and the balance of sweeteners used. Xtra is formulated to deliver a taste that is perceived as more intense and closer to the original full-sugar experience than the standard Sugar Free version. This is often achieved by adjusting the levels of sweeteners and flavorings. For instance, some users note that Xtra is "sweeter and somewhat tastes like the normal one," while others find Sugar Free to have a different aftertaste. The choice between the two often comes down to personal preference for the taste profile.
Where to Find the Sugar-Free and Full-Sugar Versions
- For the sugar-conscious: 'IRN-BRU Sugar Free' and 'IRN-BRU Xtra' are stocked by most major supermarkets and retailers that sell the brand. They are clearly labelled with their names and are typically sold alongside the regular version.
- For the full-sugar purist: 'IRN-BRU 1901' was initially a limited edition but was made a permanent product in 2021. It is brewed with the original 1901 full-sugar recipe, offering the authentic, pre-reformulation taste. It is usually sold in distinctive glass bottles and can be found in larger supermarkets and specialty stores.
