MIchael, you are probaboy in a position to comment on the actual statistics, but Napa and Sonoma especially have changed from big machine picked commercial growers to very high end, carefully picked by hand and much higher qualaity wine than what was Napa or Sonoma in the 70s. A fairly small percentage of all California wine is from the NApa and Sonoma valleys and the vast quantity of Calif wine comes from the Central Valley where the wine is a much more modest price as well as quality. NOt to say there isn't lots of good wine in other areas, Mendicino, etc but that the big commercial companies that produce the mega volume are not Napa or Sonoma. Correct me if I am wrong, Michael.
