Averna Sour

A rich, frothy sour built around the deep caramel and citrus complexity of Averna Amaro, lifted by lemon and a silky egg white foam.

Averna is one of the most historically grounded amari in the Italian tradition, produced in Caltanissetta in Sicily under circumstances that are both well-documented and genuinely unusual. In 1868, the Benedictine friars of the Abbey of Santo Spirito in Caltanissetta gifted Salvatore Averna — a local cloth merchant who had been a generous benefactor to the abbey — the formula for an herbal liqueur they had been preparing internally. The Benedictine order had a centuries-old tradition of producing medicinal herbal preparations, and the Averna formula reflected this heritage: a blend of herbs, roots, citrus peel, pomegranate, and caramel color macerated in alcohol, producing a dark, bittersweet liqueur with a particular warmth and roundness that distinguishes it from the more aggressively bitter northern Italian amari. Salvatore Averna began producing the liqueur commercially and registered the brand in 1868. It was awarded the Royal Warrant of the House of Savoy in 1895, appearing on the bottle's label as evidence of royal endorsement. Averna became one of the most widely distributed amari in Italy and internationally, acquired by the Campari Group in 2014. Its flavor profile — less aggressive than Fernet-Branca, more complex than Aperol, with notes of licorice, citrus, and sweet herbs — makes it particularly well-suited to the sour format, where its inherent sweetness functions as the sugar component while the lemon juice and egg white provide acid and texture.
