Campari has one of the best global marketing plans I have ever witnessed. From the largest city to the remotest island you will find Campari on the back bar. I have always been amazed at how they can accomplish this. Annually they sell almost 3 million cases in 190 countries; this is unbelievable coverage. You may enjoy this alluring bitter-sweet concoction on the rocks with a slice of orange, in a tall glass with soda, or as a refreshing Americano (mixed with red & white sweet vermouth & soda) this could be an arguable point with some, but I have always mixed it with both red & white sweet vermouth, although equaling the same quantity. Then there is the famous Negroni cocktail (mixed with sweet vermouth & gin) and usually served straight up although, there are times that I prefer it on the rocks . Other bitter aperitifs are: Aperol, Byrrh from France, Fernet Branca, Cynar (whose main ingredient is artichoke) and the non-alcohol bitter aperitif Crodino, even though made in Italy its main market is Germany.
