The most widely planted wine grape in the world is the Cabernet Sauvignon grape, which is grown in nearly every major wine-producing country. It is a thick-skinned grape variety that produces rich, full-bodied red wines with black fruit flavors, tannins, and a long, complex finish. Cabernet Sauvignon is often blended with other grape varieties, particularly Merlot, in Bordeaux-style blends, and is also grown as a single-varietal wine in many regions, including California, Chile, Australia, and South Africa. Its popularity has led to widespread planting and cultivation, making it the most widely planted wine grape in the world today.
