Red seedless 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 seedless 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 thin skin may also contain a dusty film, also known as a bloom, and this layer forms a natural waterproof barrier which prevents the delicate skin from cracking. The translucent flesh is juicy and is considered seedless, though a few small undetectable and undeveloped seeds may be present. Red seedless grapes are firm, crisp, and sweet with a mild, neutral flavor.

Black seedless grapes are small to medium in size and are round to slightly oval in shape. Their skin is deep purple to nearly black, and some varieties may have a waxy bloom or film on the surface to prevent moisture loss. The skin is firm and does not slip from its flesh. The flesh is translucent, tender, and less crunchy than most red or green table grapes. Although Black seedless grapes are defined as seedless, occasionally they will contain one to two almost unrecognizable tiny, edible, fleshy and underdeveloped seeds. Black seedless grapes are juicy with a sweet, grapey muscat flavor.

Green seedless grapes are small to medium in size and are round to slightly oval in shape, growing in tight or loose clusters depending on the variety. The skin ranges from yellow-green to bright green and is typically crisp, firm, and smooth. The flesh is pale green, semi-translucent, and seedless, though some seedless varieties may have a few underdeveloped seeds that are undetectable when consumed. Green seedless grapes are mild and sweet with a slightly tart flavor.
