Purple grapes are small, round fruits that grow in clusters on vines. They are known for their sweet flavor and juicy texture. These grapes can be eaten fresh or used to make products like grape juice, wine, and raisin. They are rich in vitamins, antioxidants, and other beneficial compounds. The color of purple grapes comes from natural pigments called anthocyanins, which also provide health benefits. These grapes are typically harvested in late summer to early fall. Popular varieties include Concord and Black Corinth, each with unique tastes and uses in cooking and baking.
