When a Courvoisier executive famously blew off Jay-Z's endorsement of his product, he had no idea of the consequences. Jay-Z has since officially switched his allegiance. The rapper/executive has given an obscure champagne, The Ace of Spades, his seal of approval, and business is booming. Also called Armand de Brignac, the Italian champagne costs over $350 dollars a bottle and comes from a vineyard tended by only 20 employees. Jay-Z unveiled his new drink of choice in a music video in 2006 and since then it has appeared "on the lips of celebrities from George Clooney to David Beckham, as well as in the gift bags of Oscar nominees." Now, the owners of The Ace of Spades expect to maximize their output by producing 82,000 bottles within three years. And they have no harsh words for the hip-hop world.
