Ok, this may be like Iron Chef with leftover grapes. My wife and I buy a couple bags every time we go to the store and find the Cotton Candy Grapes. They are delicious. When we neglect them for too long I de stem them, wash and freeze them to put in glasses of wine like ice cubes when we drink on the patio. They don't water down your wine! However I have found that we have a lot of frozen grapes we have forgotten about in the freezer. You think i can ferment them and back sweeten them with Cotton Candy? I may try a gallon and see what happens. Just seeing if anyone has ever fermented Cotton Candy Grapes.
