Coca-Cola Black Cherry Vanilla and Diet Coke Black Cherry Vanilla were varieties of Coca-Cola that were launched in January 2006 by The Coca-Cola Company in United States. The diet version was sweetened with a blend of aspartame and acesulfame potassium and was marketed as part of the Diet Coke family. It was available in 20-ounce, 2-liter, and 12-pack can forms. The release of this product coincided with the phasing out of Vanilla Coke and its diet counterpart in North America and the rechristening of Cherry Coke as Coca-Cola Cherry.
