High Quality Content by WIKIPEDIA articles! TaB Energy is marketed as a low calorie energy drink named after TaB, Coca Cola`s original low-calorie cola brand. While it shares the TaB name, it is not a cola product like the original TaB. Fashion Week Daily describes it as a “sweet and sour beverage” with a taste “reminiscent of a liquid Jolly Rancher”. Some drinkers alternatively label the taste as reminding them of strawberry or watermelon Nerds, and find it bitter yet quenching. Others still find that it has a distinct leafy taste. It is sweetened with sucralose (rather than saccharin), is pale pink, and lightly carbonated.
