While many will poo-poo the suggestion, my perhaps unsophisticated palette tells me that the wines from this area rival those of the Napa Valley and Europe. It is not like I have not tried them while there, just that these wines are excellent as well. It would seem to me that winemaking used to be an art/craft that was quite difficult to learn and practice successfully. Now it seems to me that it has gotten to be more of a science with even the less-expensive wines being quite good. Or perhaps it is just me and the dwindling sensitivity of my palette. Anyway, you can get a notion of the character of the area from these websites. A mix of back-home country living and some of the finer things ...just hop over the barbed-wire fence.
