Aperol is an aperitif amaro invented near Padua, Italy in 1919 by the Barbieri family. It is a citrus-based amaro, with the addition of rhubarb, gentian and chinchona bark. Aperol is now owned by the Campari group.
Aperol is artificially colored bright, neon orange. With only 22 proof, Aperol is quite sweet, with only a light bitterness, which makes it a great stepping stone into the world of amari. The citrus component is strong, and sweet and sour.
Aperol is famous for the Aperol Spritz: white wine or Prosecco, Aperol, and sparkling mineral water. It's a light, refreshing, summertime drink.
