Summer Royal is a mid-season black seedless grape. The berries are medium to large in size and round in shape. The colour is blue-black, often with a pale green area near the stem attachment. The skin is of medium thickness, offering some resistance on biting and crunch on chewing, with some astringency. To eat, the berries are quite firm and crisp in texture. There is good sweetness and often a slight acidic tang, though flavour tends to be neutral.
Summer Royal is often regarded as one of the first black seedless grapes of the season from a production region.
