Before I answer, I have to first discredit the Champagne response. If Andre is looking solely at the large houses, I can possibly see a point since many of them go for a house style. But once you leave the negociants and get into Recoltant Manipulant, and to some extent Cooperative Manipulant, wines, it's an entirely different story. These wines are all about grand cru character, and nearly all represent tremendous values. Nope, hard to call them overrated. I'd have to go with Jim and say Napa, perhaps even extending it to California in general. When there is seemingly little rhyme or reason to what grapes are planted on what parcel of land (to wit: "chardonnay is becoming passe; rip 'em up and plant merlot"), there is little to hold my interest. Compound that with prices that are out of line, and dollar for dollar you'll get better wine just about anywhere else. And that goes for both the $10 bottle and the $100 bottle.
