Aperol is an Italian aperitif made of bitter orange, gentian, rhubarb, and cinchona among other ingredients.
Aperol was originally produced by the Barbieri company, based in Padua, but is now produced by the Campari company. While Aperol was originally created in 1919, 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. However, Aperol is milder and less bitter. Campari is also much darker in color. Aperol to be sold in Germany has an alcohol content of 15% to avoid German container deposit legislation regulations. The Spritz, an aperitif cocktail, is often made using Aperol, then known as an Aperol Spritz.
