The Rum Runner is bright, tropical, and fruit-forward, with white and Jamaican rums providing a layered, funky-rum backbone. Pineapple and lime juices bring juicy, tart citrus lift, while simple syrup softens the edges, and a dash of Peychaud’s bitters adds subtle aromatic spice and color. It drinks like a vibrant, easy-drinking tiki-style cocktail with balanced sweetness, citrus, and a hint of bitters.
