KD, one of the great enjoyments of wine is to go to the various state websites and see what folks like to grow in the state. In Pennsylvania, for example, the "roster of award-winning Pennsylvania varietals includes: Cabernet Sauvignon, Catawba, Cayuga, Chambourcin, Chardonnay, Gewurztraminer, Pinot Gris, Pinot Noir, Reisling, Seyval Blanc, Vidal Blanc, Vignoles - and, yes, even wine made in the Champagne manner!"
Of course, Pennsylvania is a very large state, and some grapes might well do better in one area than another. And, home winemakers make some excellent wines in Pennsylvania.
Connecticut has a good site at http://www.ctwine.com/
and Colorado has one at http://www.coloradowine.com/
