Aperol is an Italian aperitif originally produced by the Barbieri company, based in Padua. Aperol is now produced by the Campari company. Its ingredients are, among others, bitter orange, gentian, rhubarb, and cinchona. Although it looks, tastes, and smells much like Campari, Aperol has an alcohol content of 11%—less than half of Campari. Aperol is the main ingredient in Spritz.
