Orange bitters are abundant in classic cocktail recipes. This version -- 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 any spirit. We’re personally very fond of what it does to a gin martini.
