Frontenac is a cold-hardy hybrid red grape developed by a team at the University of Minnesota. Virtually unknown in Oregon, it produces a smooth, plummy wine with sufficient acidity and moderate tannins. In the Midwest it is made into Port-style dessert wines; here it's done as a dry red of little distinction.
