The line, which launches in April, contains caffeine and is intended to sharpen mental performance. It will comprise a Lemon Zing flavour variant that contains 45 calories per 250ml bottle.
The launch will be backed by a £4m marketing campaign through M&C Saatchi, encompassing outdoor, press ads, point-of-sale and sampling activity. The ads will direct consumers to a microsite developed by Fuse Digital that features challenges and games consumers can play to discover how mentally alert they are.
