George: Actually, cab franc is less difficult than cab sauv in some ways. And it is used as a single varietal in Loire, though the style is normally more fruity (though not a fruit bomb) and less tannic than Niagara and NY cab franc. JL Groux, currently at Stratus and formerly at Hillebrand, is from Loire and is a master of the grape, IMO. It matures about 2-3 weeks earlier than cab sauv, so often does better in colder climates when the summer is challenged. I suspect that this year will be better for cab franc than cab sauv.
