Brown-Forman is adding Black Jack Cola, a cola-flavored drink with a "hint" of lemon and lime, to its line of ready-to-drink Jack Daniel's Country cocktails. Black Jack Cola will be available nationwide in May, and will be available in 10-ounce four-packs retailing at US$5.99.

"With the increased popularity of cola and citrus flavours, it only makes sense to introduce a unique twist on America's cocktail in the convenience of a pre-mixed drink," said Chris Vignoe, brand manager for Jack Daniel's Country Cocktails.

The brand already consists of six other flavours and generates annual sales of 2.2m flat cases.
