Autumn Royal Grapes

Autumn Royal is a late-maturing black seedless table grape created by the USDA-ARS in Fresno, California's David Ramming and Ron Tarailo. The cultivar, which was formerly known and evaluated as USDA selection A97-68, was introduced in 1996 and is the result of a 1981 cross of Autumn Black x C74-1.

Late in the season, the grape 'Autumn Royal' ripens into enormous, delicious purple-black fruits with vibrant yellow-green flesh. The seedless grapes have a thin skin and a wonderful sweet flavor. They also have a rich, sweet flavor and a strong, crunchy texture, making them a great dessert grape. If grown outdoors, this modern, Californian-bred cultivar prefers a warm, sheltered environment.

Grapes have health-promoting properties due to their high concentration of bioactive phenolics. Grape juice made from blue grapes (Autumn Royal, Ribier) has more phenolics and antioxidants than juice made from red grapes (Red Globe, Crimson Seedless). The skin is high in antioxidants and contains a lot of phenolics. Blue grapes have higher levels of specific health-promoting phenolics, primarily in the skin portion, which should not be discarded.
