Dolcetto is *not* a blending grape. It is used to make varietal wine meant to be drunk in its youth as a table wine in Italy. The Pinot Noir Nazi should stick to French varietals, methinks.

As for Cab Franc, it has a distincive flavor profile to be sure. It's rare for me to come across a varietal version that I love, but it happens. Certain Bourgeuil & Chinon will do the trick nicely. And, there's one I've come to rather like from up here in WA.
