Bartending legend & maestro of mixology, Gary Regan developed his zesty bitters back in the early 1990's building on a recipe in Charles Baker's The Gentleman's Companion. 

The citrus flavors and aromas are decidedly forward but not overpowering, allowing them to play well with nearly any spirit . The recipe includes orange peel, cardamom and coriander along with the classic bittering agents cinchona bark, quassia and gentian root. 

Use it in your favorite whiskey drink!
