Coca-Cola Enterprises (CCE) says it is boosting the energy drinks sector this spring with the launch of a new variant - Relentless juiced energy berry.

The new drink, which contains 50% juice including strawberry, raspberry and blackcurrant, is available now and is being supported as part of a £6m marketing investment for the brand.

CCE says the energy drinks sector has grown by £72m in the past year with Relentless accounting for 30% of this growth (AC Nielsen, total coverage, value sales, 52 w/e 23/08/2008).

To celebrate the launch of Relentless juiced energy berry and the growth within the category, CCE has five prizes up for grabs, each comprising three cases of the new variant.
