Duetto

[Zinner]

Duetto is one of Wente Vineyards international ventures...a wine blended from fruit from Mexico and from California, which is how it gets the name.
I had the '96 Duetto in June at a dinner that Wente hosted at VinExpo(trade show for wine and spirits) in Bordeaux. If memory serves me correctly, they introduced it at VinExpo two years ago.
I agree that it's worth seeking out.
Wente Vineyards can be contacted at 5050 Arroyo Road, Livermore, CA 94550. Phone is (925)456-2450.
I'm sure they'll be glad to send you all the info you want.
