Red grapes are small to medium in size and are round to slightly oblong in shape, growing in medium to large clusters. The hue of a Red grape can vary widely depending on the variety and local growing conditions, but it usually ranges from a light red to a deep burgundy. The translucent flesh is juicy and is considered seedless, though a few small undetectable and undeveloped seeds may be present. Red grapes are firm, crisp, and sweet with a mild, neutral flavor. Red grapes contain significant amounts of vitamins A, C, and K, and contain flavonoids, such as resveratrol, which provide high antioxidant qualities that can help boost overall health.
