Jack Daniel’s Tennessee Cocktail Bitters are made with the finest flavors from around the world. Notes of vanilla and wood work hand in hand with what is in a bottle of Old No. 7, while hints of dark berry, maple and ginger complement the flavors of the whiskey to elevate your favorite cocktail. These aromatic bitters are made specifically to work with the flavors of Jack Daniel’s. Add a few drops to cocktails that call for bitters and even some that don’t, says ET Tecosky, Jack Daniel’s U.S. Brand Ambassador.
