Black Walnut Bitters add a deep and rich earthiness to your cocktail. Unlike other bitters, Bluegrass Bitters uses true black walnut and a complement of baking spices to create this complex and aromatic flavor. These are best suited for Old Fashioneds, Manhattans, or holiday ciders, but also work well with other dark spirits and make an outstanding Bitters and Soda when added to ginger ale. The Black Walnut was the toughest recipe to crack, with over two dozen different recipes being tested before deciding on this version. This is sold as a 12-pack case of 2-oz bottles with pipettes.
