    Storage

    Apart from selection, proper storage of the grapes is also a pre requisite for keeping the fruits fresh and avoiding any injury or decay. Unwashed grapes should be kept in a plastic bag or airtight container and stored in the coolest part of the refrigerator. Grapes can be stored up to a week but their quality diminishes with time. Wash them well before serving.
