Using a proprietary formula that has been unchanged since its first production in 1919, Aperol's distinctive taste and color is accomplished by a subtle combination of bitter orange, gentian, rhubarb, and an assortment of herbs and roots. Try the Aperol Spritz classic: 3 parts of Aperol, 2 parts of Prosecco, 1 part of soda with an orange twist over ice. It's one of the ultimate drinks for thirst-quenching.
