One of the biggest names in the wine-making business, Opus One started out as a collaborative venture between Robert Mondavi and the late Baron Philippe De Rothschild. A sprawling winery, it uses only state-of-the-art production techniques and turns out about 25,000 cases of wine annually. Priced at $150 a bottle, it certainly is a hefty price for a bottle of wine. Wine connoisseurs, however, don't seem to mind paying this sum at all - Opus One is reputed to produce some of the best wine in the world.
