Store grapes unwashed in an open plastic bag in the refrigerator for up to a week. Freezing grapes is a simple but useful way to store grapes, simply wash and pat dry the grapes, and then arrange individual grapes in a single layer on a sheet freeze and then transfer to an airtight container or plastic freezer bag.
Like all fruit, grapes should be rinsed before consumption. Grapes are great just eaten out of the hand, but can be tossed into salads, yogurt and cereal. Frozen grapes make a great dessert or a nice summertime snack.
