Tuaca® Vanilla Citrus Liqueur - According to legend, the origins of Tuaca's secret recipe date back to the Renaissance and a drink crafted for Lorenzo de' Medici. In 1938, Tuoni and Canepa rediscovered and mastered the recipe that they named Tuaca. This smooth, yet bold liqueur with an inviting taste of vanilla and citrus was finally brought to the United States in the late 1950's. Tuaca is best served cold and straight to enjoy its complex character but is also great in a variety of drinks.
