Freeze Your Grapes!
First of all, frozen grapes make a delicious snack to begin with. So, you should always freeze at least a few for a nice refreshing snack. Secondly, frozen grapes make great ice cubes for wine! It's always a bummer when you realize that your nice white wine wasn't refrigerated and that you may have to use ice cubes. Using ice cubs waters down the drink, which isn't very tasty. Using frozen grapes doesn't water down your wine, keeps it cold, and you get to eat grapes when you're done!
