AG Barr has added blue raspberry flavour to its Rockstar SuperSours range. The firm says SuperSours was one of the most successful energy launches of last year and has so far delivered over £11m through retailers’ tills. AG Barr head of marketing, Adrian Troy, said: "Within ’big can’ energy, flavoured variants are still the key drivers of growth in the category, up by 52% (Nielsen). Rockstar is leading this trend with a 56% share of the flavoured energy market and seven out of the top 10 fastest-selling ’big can’ energy drinks."

The latest flavour received excellent feedback in consumer taste tests, with 81% of those asked saying they would buy the product.
