The pre-mixed spirit drink Bacardi & Cola has been redesigned to give it a more premium image. And the new look is to be accompanied by the launch of a diet variant, which Bacardi claims will make the drink the only brand in the market to offer a low calorie variant. Bacardi said that "diet" now accounted for 46% of the total cola market and in Bacardi's case 90% is drunk with cola, with one in four people choosing diet. All this means "massive untapped potential for this drink," the company said.
