From next month, coffee Revels will be temporarily replaced by a new mystery variant – thought to be strawberry because of the pink colouring on the limited-edition packs. The launch of Revels Mystery Sweet packs, which will be on shelf until the end of the year when the coffee variant will be reintroduced, follows the £2m Revels Eviction campaign earlier this year.

“The new pink design maximises stand-out on shelf and alludes to the new flavour,” said Bep Sandhu, trade relations manager for Mars.
