There are two varietals known as Cabernet: Cabernet Sauvignon and Cabernet Franc. Cabernet Franc is the original Cab, and Cab-Sauv is the result of a cross between Cabernet Franc and Sauvignon Blanc back in the 17th century. Cabernet Franc has stayed predominantly in France, but Cabernet Sauvignon has spread far and wide to become one of the most widely planted red wine grapes in the world. Both are usually high in tannins and acid, which make them good for aging. The dominant flavors in Cabernet Sauvignon are cherry and currant, as well as some vegetal notes such as bell pepper and mint. Cabernet Franc is most commonly used for blending in Red Bordeaux wines, where it brings flavors of strawberry and bell peppers and possibly a hint of violet and licorice.
