Ciroc was an also-ran in the vodka world in 2007, selling a mere 40,000 cases that year. Of course, that was before Sean "Diddy" Combs came on board as Ciroc's brand ambassador. A mere four years later, the brand sold 1.5 million cases, making it a major player in the vodka world and proving once again that Diddy—or as he sometimes calls himself, "Ciroc Obama"—is a money making machine, having bought into the business for 50% of the profits. Ciroc is an unusual vodka, distilled from grapes instead of the usual potatoes or grains, and it's more flavorful than your typical odorless-colorless-tasteless vodkas. It's even been compared to a grappa. If you think typical vodka is a little too dull, or if you just like Diddy's Rat Pack-homage commercials, Ciroc is well worth a try.
