50 (41) Volvic

Last year’s ranking: 41

Sales: £163.7m (-6.9%)

Volvic has blamed “distribution decisions” by Tesco, Asda and Morrisons in 2016 for sliding sales over the past 12 months or so. In the latter part of 2017, Britain’s biggest water brand set its sights on a ­turnaround. It invited ­moviegoers to Find Your Force as it partnered with Disney’s Star Wars: The Last Jedi movie to make water “more fun for kids”. This year it is taking aim at the growing flavoured water market with a relaunch of Touch of Fruit Original planned for April.
