Created in California in 1996, Cotton Candy grapes are medium to large in size, and have a seedless, juicy flesh that tastes just like cotton candy as it is very sweet, and has a soft, but crunchy texture. Nutritionally, these unique grapes are a good source of vitamins A, C, and K, antioxidants, and flavonoids. Cotton Candy grapes also contain the antioxidants lutein and zeaxanthin, which can help maintain eye health.
