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.
