Concord grapes - can I freeze and, if so, anything special I need to do?

Thank you for the responses. I ended up freezing the peels and the pulp separately so that I can make more pies later. The grape-lemon soda looks fantastic - I imagine I could use the frozen peels and pulp for that (and then add a shot of alcohol!).

I've always thought a great hot-weather treat was to plop a frozen grape into my mouth, so I often freeze them. But that's different than freezing them for a later thawed use; you could expect some mushiness from the freeze-broken cells in the grape, just as you would from almost any frozen fruit. In any case, the best way to freeze them is to take them off the stems; wash and dry them; then arrange them in a single layer on a baking sheet or pan that fits in the freezer. When thoroughly frozen, remove from sheet; put into zipper bags; and return to freezer.

I don't know about freezing, but would think you could. This recipe jumps at me if I had some concord grapes though, http://www.food52.com/recipes/14519_concord_grape_and_lemon_soda
