"Bold flavor with rich antioxidants"
These dark-hued grapes are prized for their intense, wine-like flavor and high antioxidant content. Unlike seedless varieties, seeded grapes offer a more complex sweetness and a characteristic musky aroma, often featuring a protective silvery bloom on their deep indigo or midnight black skins.
