GlaxoSmithKline is to launch a flavour extension to its leading energy drink, Lucozade Energy. The flavour variant, Lucozade Energy Wild Berry, will be available from the beginning of March this year.

Henry Dummer, customer marketing controller, convenience, GlaxoSmithKline, said: "Lucozade Energy Wild Berry is set to create a buzz within the cold drinks market and drive penetration. Research shows that Wild Berry is not only very well received by current Lucozade Energy drinkers but will also bring new consumers in to the brand, researching as the number one flavour choice for new users. Retailers should stock Wild Berry alongside the rest of the Lucozade Energy range (Original, Orange, Citrus Clear, Lemon and Tropical) to generate incremental sales."

GlaxoSmithKline will be supporting the new flavour with a  £1.5m outdoor campaign.  The variant will also be backed as part of the £30m overall brand support package for 2004.
