Orange bitters is abundant in classic cocktail recipes. This version is a bourbon barrel aged bitters to differentiate from the typical vodka based orange bitters. Perfect for Old Fashioned's and any other whiskey based applications where a bourbon based bitters makes sense. -- fruit-forward, floral, and softly spiced -- offers an alternative to the one-note orange bitters that dominate the market. The secret’s in the hand-peeled orange zest, whose citrus oil smooths the edges of an exactingly calibrated mix of black walnut, gentian, clove, and cardamom. Evocative of fragrant orange groves, it’ll add new depth to any cocktail that calls for it, and has the versatility to match to any spirit.
