Americano
The Americano is a gentle introduction to the unusual, bitter taste of Campari. A true classic cocktail, it was first served in the 1860's at Garspare Campari's bar in Milan, Italy. The Americano was originally named the Milano-Torino because of the origins of it's ingredients, but was later renamed because of its popularity among American tourists during Prohibition.
This cocktail was also the first cocktail ordered by James Bond in the first novel, Casino Royale. However, the Vesper Martini (or the manner in which it was ordered) overshadowed the Americano in the books and movies.
