Hydration specialist Santeau is rebranding its O2Go water flavouring range with a new name and packaging to pacify mobile phone operator O2.

The O2Go range, which was launched two years ago to add interest to plain bottled water, will be known from this month as Wahoo.

The rebranded range has different packaging to O2Go and new flavours: summer berry, tropical and citrus. It is available now in Asda, Waitrose and Morrisons.

The range continues to be positioned as a vitamin-filled powder-based alternative to flavoured and vitamin-enriched bottled water brands such as V Water and Glaceau.

Each Wahoo sachet contained 25% of the RDA of vitamins B, B3, B5, B6 and C and would, at £1.80 per 12-pack, provide a cheaper alternative to bottled products, said the company's founder and managing director Jon Yates.
