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.
In Bordeaux, Cabernet Franc is often mixed with Merlot or Cabernet Sauvignon. Many of the red wines of the Loire are primarily Cabernet Franc, although it is called something different. Also, in California and other U.S states, it is blended to make Meritage wines.
