Things You'll Need
Muscadine grapes thrive in the southern United States, where they grow both wild and cultivated. The small purple grapes have an extremely sweet flavor, though the skins are tough and tart. Canning the grapes in jams and jellies are the typical ways to preserve muscadines, but freezing the grapes whole allows you to enjoy them in salads and other uses. The freezing process does little to affect the texture or flavor of the juicy grapes, so you can enjoy them year-round.
Separate the muscadines from the stems. Places the stemmed grapes in a colander.
Rinse the muscadines thoroughly with cool, running water. Stir the grapes gently with your hand as you rinse so they are all cleaned.
Dry the grapes thoroughly with a clean paper towel. Wet grapes stick together during freezing, and the excess moisture can lead to freezer burn.
Place the muscadines into a one-gallon freezer storage bag. Squeeze out any air in the bag and seal it closed.
Store the muscadines in the freezer for up to one year.
Spread the grapes out on a tray, and freeze them solid before transferring them to a bag. The muscadines don't stick together when frozen in this manner, allowing you to remove only a few grapes from storage at time.
