- DescriptionThanks to warm, sunny days and cool lake-side nights—plus an acidic soil native to the Seneca Lake region—Concord grapes have the distinctive flavor of grape jam with a hint of tartness and a lush gush of sweet juice. The deep purple skin slips off when you bite into a Concord, revealing transparent flesh and tiny seeds. Concord grapes make delicious eating but can also be used for juice, jam, or wine.SeasonPeak Season: Summer and Fall

It's best to eat grapes quickly after purchase. You can keep them for up to a week, unwashed, in a plastic bag in the refrigerator.
Grapes are extra-refreshing when eaten frozen. Wash and dry fresh grapes, then lay out on a tray and freeze. Transfer to an airtight container and store in the freezer, where they will keep for up to 3 months. Enjoy them frozen, but don't thaw they won't have much snap.
