As its name implies this grape has a distinctive flavor that does, remarkably, taste very much like the spun sugar confection. This is not a genetically engineered product; but rather a tedious hand-pollination process that was employed.
Grapes (Cotton Candy®)
These grapes have an initial burst of candied flavor that than recedes into a mild, juicy sweetness. They are low in acid and definitely sweet without being overly sugary. "Cotton Candy® Grapes are a trademark of IFC. Used with permission."
