A new launch, available exclusively in Tesco and One Stop from May 2026 ahead of a nationwide rollout from late July, bringing the brand's best-selling US Ultra flavour to British shelves for the first time.

The flavour pairs ripened guava with Monster's signature energy blend, delivering a zero calorie, zero sugar drink built around a flavour that has grown by over 22% in popularity across the past two years. In the US, Vice Guava has become Monster Ultra's best-selling variant, and the company is banking on the same demand translating to the UK market.

The can design is bold and unmistakably 80s, drawing on Miami Vice-inspired styling in vivid green and hot pink, designed for maximum standout in the chiller. Beyond the visual impact, the can also has a genuinely pleasant textured feel to the touch, giving it a tactile quality that sets it apart from the smoother finish of most standard Monster cans.

Monster holds a 55% share of the UK's low-calorie energy drink category, a segment now worth £631 million in Great Britain, and Vice Guava follows the earlier 2026 launch of Monster Juiced Viking Berry as the brand continues to expand its zero sugar portfolio. Available in both plain and price-marked 500ml single cans at an RRP of £1.75.

This sits alongside Monster Ultra Peachy Keen also in the PullTab archive, both representing the brand's growing fruit-led Ultra range that continues to push zero sugar energy drinks into bolder, more flavour-forward territory.
