Aperol was originally produced by the Barbieri company, based in Padua, but is now produced by the Campari Group. While Aperol was originally created in 1919, by Luigi and Silvio Barbieri, it did not become successful until after World War II. Although it tastes and smells much like Campari, Aperol has an alcohol content of 11%—less than half that of Campari. Aperol and Campari have the same sugar content, and Aperol is less bitter in taste. Campari is also much darker in colour.
Aperol is an Italian bitters apéritif made of gentian, rhubarb, and cinchona, among other ingredients. It has a vibrant orange hue. Its name comes from the Italian slang word for aperitivo, which is apero.
