Enjoy Campari the Italian way by mixing it with soda water or wine. The easiest way to enjoy is on the rocks garnished with a slice of orange. There are, however, several recommended cocktails that helped put Campari on the international map including the ' Negroni' & ' Americano': Negroni:- 1 part Campari- 1 part Gin- 1 part Cinzano Rosso Add ice to a tumbler, mix all the liquid & garnish with a slice of orange Americano: Replace the Gin in a Negroni with Soda Water.
