Smooth and easy drinking.Cabernet Sauvignon is its affinity for oak, either during fermentation or in barrel aging. In addition to having a softening effect on the grape's naturally high tannins, the unique wood flavors of vanilla and spice complement the natural grape flavors of blackcurrant and tobacco. The particular success of Cabernet-based Bordeaux blends in the 225 liter (59 gallon) barrique were a significant influence in making that barrel size one of the most popular worldwide.
