Campari is the key to the Negroni, which is one of the best aperitifs you will find. Campari can be an acquired taste that some people will love while others will not, though the nice thing about this cocktail is that the sweet vermouth offsets some of the bitterness of the Italian spirit. This also makes the Negroni a nice drink to train your tastebuds to enjoy bitter aperitifs.
It is widely believed that the Negroni was created and named for Count Cammillo Negroni in the 1920's when he ordered an Americano with gin at Cafe Casoni in Florence, Italy.
The Negroni can also be shaken and served in a cocktail glass with a lemon twist.
