Muscadine Grape. Black self-fertile, very productive, very high sugar content. Early to mid season. The muscadine berries range from bronze to dark purple to black in color when ripe. They have skin sufficiently tough that eating the raw fruit often involves biting a small hole in the skin to suck out the pulp inside. Muscadines are not only eaten fresh, but also are used in making wine, juice, and jelly.
