Coca-Cola Co is to launch calorie-free versions of its Vitaminwater drinks in the US early next year.

Vitaminwater zero will launch in 20oz bottles across the US from early next year, Coca-Cola Co said yesterday (17 November).

The group has substituted sugar for Truvia, which is part of a new generation of sweeteners derived from the Stevia plant and cleared for use by the US Food and Drug Administration last year.

"Vitaminwater zero provides an ideal option for calorie-conscious consumers looking for a great-tasting beverage with the added benefits of vitamins and electrolytes," said Matt Kahn, senior vice president of marketing for vitaminwater.

There is already a 10-calorie version of the brand, named Vitaminwater10.

Vitaminwater zero will be available in seven flavours: xxx (acai-blueberry-pomegranate), multi-v (lemonade), essential (orange-orange), mega-c (grape raspberry), go-go (mixed berry), recoup (peach-mandarin) and revitalize (green tea).

Also yesterday, Coca-Cola Co announced a rebranding for its global juice range.
