A mix of strawberry and lemon fruit juices blended with premium vodka, Jamaican rum and wine, it joins the range's three original flavours launched in 2001.
All four variants have an abv of 14.7% and are packaged in frosted 70cl glass bottles with an rsp of £5.99.
Karen Salters, Beverage Brands' marketing manager, said: "We saw an enormous uplift in sales of multi-serve bottles in 2002 with an increasing number of people choosing 70cl bottles."
Ian Dobson, spirits buyer at Safeway, where the flavour has secured its first listing, said he worked closely with Beverage Brands to develop the new variant. "We have been pleased with the brand's performance over the past 18 months," he said.
