Is Cabernet Sauvignon Sweet? Cabernet Sauvignon is generally a dry red wine rather than a sweet one, as most of its natural sugars are converted into alcohol during fermentation. While it has bold flavors of dark fruits like blackberry, black cherry, and plum, these fruit notes do not indicate sweetness but rather add to its rich and complex profile. High tannins and moderate acidity contribute to its dry, full-bodied character, making it a favorite among red wine enthusiasts.
