Regans' Orange Bitters No. 6, created by renowned cocktail expert and author Gary Regan, is a timeless staple in the world of mixology. Inspired by a vintage recipe from Charles H. Baker, Jr.'s The Gentleman's Companion, this bitters blend is a harmonious marriage of citrus zest, warm spices, and classic bittering agents. The forward citrus flavors of bitter orange are masterfully balanced with cardamom, caraway, and coriander, while the inclusion of gentian, cinchona, and quassia adds depth and complexity. Its versatility makes it a go-to choice for enhancing cocktails across a range of spirits, adding brightness and nuance to any drink.
