The comeback took a different route. When PepsiCo and Britvic brought it back in April 2010, they did not sell it as a soft drink at all. They positioned it as Mountain Dew Energy and aimed it squarely at a stimulant drinks category that was then the fastest growing in Britain, worth £567 million and dominated by Red Bull and Monster. That worked, and in 2015 the brand reformulated again, dropped some of the caffeine, renamed itself Citrus Blast and quietly moved back to being a soda. The 440ml cans were replaced by 330ml at the same time.

The can reflects that history in its colours. A bright citrus green dominates the body against black, with red accents carrying the Mountain Dew wordmark, a palette that sits closer to the energy chiller than the fruit carbonate shelf even though the product no longer claims to be an energy drink. The £1.00 is printed directly onto the can as a price marked pack (PMP), which fixes the price at the point of manufacture rather than leaving it to the retailer, a format used heavily in convenience stores and independents where impulse purchases dominate.

Inside is a citrus soda made with carbonated water, sugar, citric acid, flavourings including caffeine, ascorbic acid and beta carotene for colour. That beta carotene is worth noting, because it is a natural colouring, where the American version uses artificial Yellow 5. The two drinks share a name and very little else.

It now delivers £29.2 million in annual retail sales in Britain and grew 10.1% year on year, with a 1.5 litre format added in August 2025 alongside the existing 500ml bottle and this 330ml can. It is made under the authority of PepsiCo by Carlsberg Britvic in Hemel Hempstead.
