Autumn royal grape is a large variety of black seeds from California with many benefits. The seedless black grapes are round to slightly oval, and the peel is deep purple to close to black with a waxy bloom. The skin is firm and does not slip off its flesh. The flesh is tender to the touch and distinctly juicy with a sweet, strong, and musky flavor. Although seedless black grapes are defined as seedless, they sometimes contain one to two small fleshy seeds that are nearly indistinguishable. Season / Availability Autumn royal black grapes are usually from mid to late summer through early fall. Autumn Royal (Vitis vinifera “Autumn Royal”) is a late-ripening, seedless black grape that ripens in late September to mid-October, developed by gardeners at the University of California, Fresno. Autumn royal grapes can be grown in a Mediterranean climate. 1.The royal sock bear plant falls 6 to 8 feet tall in early spring. Plant in a sunny, well-drained location in soil with a pH of 6 to 6.5. Fertilize each plant with ½ to 1 ounce of nitrogen using a balanced fertilizer and well water. A balanced fertilizer containing equal amounts by weight of nitrogen, phosphorous, and potassium. 
2.Slender shoots grow from the stem when they are 6 to 12 inches long. Leave two twigs on each spur or bud along the perimeter or "arms" of the grape vines. 3.Train the vines to a T-trellis. The trellis pole should be 8 feet high and buried 3 feet in the soil and topped with a 5-foot cross-section. In a favorite quad canopy, reeds grow on wires that extend from either side of a tee. Rows should be 11 to 12 feet apart. 4.Prune the garland branches that extend to the sides of the tee from December to January. Leave 24 to 32 buds on each vine. This is called super pruning. 5.Remove the basal or lower leaves from the stem up to the first five nodes. They rarely affect the growth of grapes, and removing them helps prevent disease. 6.Water deeply every two to three weeks during the growing season, drip irrigation is preferred. In hot spots indoors, each vine needs 6 to 8 gallons of water. Fall Royal grapes grown on the coast or in Northern California will need less water. If you let the vines dry out too much, wet them, and the grapes may burst. 7.Apply 1 pound of ammonium sulfate, 3/4 pound of ammonium nitrate, and 1/2 pound of urea to each plant after flowering or when setting grapes. Grapes are set when they are 1/4 inch wide. Apply 5 to 10 pounds of compost per plant in January or February. Spray 1/10 pound of zinc per gallon one week before the vines bloom, or during blooming, but one week before blooming. 
8.Cut the branches to about 3 or 4 feet above the ground in early summer. The shoots can reach 10 feet or more in the growing season. This makes it easy to manage Chrome. Summer pruning leads to more growth in mid-to-late summer. 9.Apply 2 to 3 grams of gibberellic acid per acre when 75 to 80 percent of the flowers are ripe. This will increase the size and length of the grapes and reduce the number of grape seeds. GA is a plant growth hormone that affects cell growth and elongation. 10.When the grapes are installed, fasten the stems with a double-blade knife. Strapping is the practice of removing a 1/8-, 3/16-, or 1/4-inch-wide strip of bark from the sticks that support the vines. The belt removes a thin layer of bark and cambium from the reeds but not from the wood. The phloem and cambium consist of tubes and tissues that transport sugar and phytonutrients to the grapes. The belt disrupts the flow of nutrients down the stem, sending them all to the vines. Bunching will increase the weight of the royal fall grape by 10 to 15 percent. Autumn royal juice provides the highest number of phenols and anthocyanins, and exhibits the highest antioxidant capacity, providing health-promoting properties compared to other grape varieties studied. Practical Applications: Grapes have health-promoting effects due to their supply of a wide range of bioactive phenols. Grape juice made from blue grapes (Autumn Royale, Ribier) showed higher phenols and antioxidant capacity compared to the juice extracted from red grapes (Red Globe, Crimson Seedless). 
The skin is a good source of phenols and has a high antioxidant capacity. Certain health-promoting phenols are more abundant in blue grapes, especially in the cutaneous part, which should not be discarded. Grape seeds and their skins are good sources of phytochemicals such as gallic acid, catechin, and epicatechin and are suitable raw materials for the production of antioxidant nutritional supplements. Differences in the levels of major mono flavones and phenolic acids were determined in grape seeds and skins of Vitis Vinifera Merlot and Chardonnay and grape seeds of Vitis rotundifolia of the Muscadine cultivar, and the antioxidant activities of these components were evaluated. The contribution of mono-flavanols and phenolic acids to the total antioxidant capacity of grape seeds and skins was also determined. Autumn Royale is a late-season black grape. It has large elongated purple-black berries with a crunchy crust, firm texture, and a pleasant level of sweetness. It is usually seedless and has attractive translucent yellow-green flesh. Under certain climatic conditions, Autumn Royal can develop a "trace" of seeds that can be seen, but are usually not detectable by a "mouth feel". However, sometimes, the seeds acquire enough hardness to be detected. Autumn Royal is sometimes susceptible to "rot," which is revealed to the consumer by the berries leaving the vine. 
Due to their late ripening, Autumn Royal offers growers high-quality season-spanning grapes from any region. Different uses of grapes:
- Bread - Grapes work just like any other berry - and they do - in baking applications, including pies, cakes, bread, and pizza (or even pancakes). Baked kraut with grapes is a classic buffet dish.
- Mix - throw them - the crust and everything - into the blender to make smoothies, cocktails, and other delicious drinks.
- Blisters - high heat does the trick (try grape seed oil for this). Cook until the skin becomes crunchy.
- Barbecue - Try the prosciutto-wrapped grapes to perch on angels on horseback. Wonderful for appetizers.
- Snip - The best way to serve grapes as a fruit dish or appetizer is to cut them into small bunches. Grapes provide great coverage, color, dimension, and flavor.
- Cups - See cup grape and lemon garnish.
- Ornamental - Grapes are a caterer's dream with three vibrant colors to work with. So go ahead, curtain, tassel, stripe b - imagination is the limit.
