Black grapes, velvety colored and deliciously sweet and juicy, can be consumed fresh and raw, dried as raisins or as a juice. Rich in nutrients, black seedless grapes are similar in taste and texture to red or green grapes, but because of their skin color, they have a higher antioxidant content. The U.S. Department of Agriculture recommends between 1 1/2 and 2 cups of fruit each day as part of a balanced diet, and eating black grapes will help you meet that goal.
Black grapes, also sometimes known as Concord grapes or slip skin grapes, are sold fresh or made into fresh juice, jams or jellies. They are rich in a number of nutrients, including natural antioxidants, and can be part of a healthy diet that reduces the number of calories you consume, helping you lose weight. 
Seasons/Availability
Black seedless grapes are available year-round, with peak season in the summer and fall.
How to Buy Black Grapes
The best way to ensure that you are buying fresh black grapes is to hold the bunch by its stem and shake them. If the grapes fall from the stem, it means they have been stored for a long time and should not be eaten. Bunches are held together if the stem is green.
Sometimes, grapes have a white coating on their surface. This coating, known as bloom, is a harmless, natural substance that provides protection against loss of moisture, fungus, and decay.
Avoid grapes with soft or wrinkled skin or stems that are brown or brittle. This might be a sign of freezing or drying. Grapes with bleached areas around the stem or leaking berries should also be avoided as they indicate poor quality or decay.
Tips on Storing Black Grapes
Proper storage of grapes is essential for keeping the fruits fresh and avoiding any injury or decay. Unwashed grapes should be kept in a plastic bag or an airtight container, and stored in the coolest part of the refrigerator. Grapes can be stored for a week, but their quality diminishes with time.
