Seco Herrerano is an alcoholic beverage distilled from sugar cane. It is distilled three times. It is traditionally used directly or in mixed drinks as a substitute for rum or vodka. What else do you need to know?

Although most assume that rum is Panama’s national liquor, it’s actually Seco—an 80-proof, white spirit distilled from sugarcane.
