Cabernet Franc is a red wine grape variety similar to and a parent of Cabernet Sauvignon. A cross of it with Sauvignon Blanc resulted in Cabernet Sauvignon.
Cabernet Franc tends to be softer and has less tannins than Cabernet Sauvignon, although the two can be difficult to distinguish. Sometimes the French refer to Cabernets, which could mean either of the two grapes. Its typical aromas include some herbaceousness, even in ripe fruit, and something eerily like tobacco. Bad-quality Cabernet Franc wines can have a slightly soapy taste.
Cabernet Franc forms part of the Bordeaux blend, usually taking a minor role to Merlot and Cabernet Sauvignon. However, one of the most famous Bordeaux, Château Cheval Blanc is primarily Cabernet Franc. Many of the red wines of the Loire are primarily Cabernet Franc, although it is not mentioned on the label. In California and other U.S. states, it is part of the Meritage blend.
It seems particularly suited to Ontario's Niagara region where it makes an excellent varietal wine. In the Hungarian wine region of Villány the grape is used in Bordeaux-style blends and is also bottled as a varietal wine.
