Last month I mentioned that Chateau Montelena, one of Napa Valley's best-known wineries, might be for sale. Now the San Francisco Chronicle reveals the new owner. Michel Reybier, owner of Bordeaux chateau Cos d'Estournel, will soon own the Calistoga property pending approval from the federal government. There has been no definitive word on a price but rumor has it that the figure is in the $100 to $110 million range. The potential deal comes at a time when attention is being focused toward the winery anyway because of the release of the movie "Bottle Shock," which centers on the events surrounding the moment when the 1973 Montelena Chardonnay outscored top white Burgundies in the 1976 Judgment of Paris tasting.
