A parent to Merlot and Cabernet Sauvignon, Cabernet Franc is another of the Bordeaux varieties. Cab Franc is lighter than Cab Sauv with different flavor profiles. It ripens a little earlier than Cab Sauv and is very popular on the East Coast of the U.S. as it has a good tolerance for cold winter temperatures. Like Cab Sauv, Cab Franc has small, thick skinned berries that have a high tolerance to diseases.
