While living in San Francisco in early 2007, Avery and Janet Glasser used a high-proof spirit and a variety of herbs, peels and spices to create an extract of a traditional Mexican cooking sauce. This extract became the prototype recipe for Bittermens Spirits. From New York to Boston, San Francisco and around the world, cocktail enthusiasts and bartenders are rediscovering long-lost recipes and coming up with new signature flavors which help create the palate of the New American Cocktail. These are the flavors that inspire Bittermens Spirits.
