Campari was invented by Gaspare Campari between 1862 and 1867. Today the product is still composed of the same original ingredients, thanks to a formula which has remained a secret for almost 150 years. Campari is obtained from the infusion of bitter and aromatic herbs, plants and fruit in alcohol and water. Campari is an essential ingredient in the classic Negroni cocktail, and, wittily, in the Americano, named at a time when few Americans were aware of Campari. Ernest Hemingway drinks Campari and Gordon’s with a splash of soda in Under Kilamanjaro.
