There are several ways you can freeze your grapes.
For easiest eating, it’s best to freeze seedless grapes.
Grapes need to be washed well before freezing. If you’re using non-organic grapes, it’s important to cleanse the skins well.
Drain grapes in a colander and/or salad spinner. You want grapes to be dry before you freeze them, so even after draining or spinning, lay them out on an old bath towel, and blot them gently with another towel. You’ll get a better quality freeze, without any additional icicles attached to grapes, if they’re dry when you put them in the freezer.
Place the grapes on a baking tray. It’s a good idea to line the tray with parchment, plastic wrap, or wax paper first. Spread out the grapes as much as you can so they don’t touch each other. This is done so that the grapes don’t stick together when they freeze.
If you want your grapes to be extra sweet, then you can sprinkle them with a bit of sugar, stevia or artificial sweetener before you put them in the freezer.
If you want to get creative, you can make “frozen grape skewers” by placing the grapes on a skewer or a few skewers before putting them in the fridge.
Place the tray into the freezer to quick freeze the grapes. After they’re frozen solid, pack grapes into freezer bags or containers. I find a tupperwear container works best.
**You can puree grapes before freezing, and freeze the puree in ice cube trays. Pack the grape cubes in freezer bags. These cubes make a great addition for chilling drinks like juices, teas, or lemonade without watering them down. For best quality, eat frozen grapes—chunks or puree—within nine to 12 months.
** To make grape popsicles. The grapes go in your blender or food processor. Blend them all together so you have a liquid to pour into your popsicle containers. Pour into ice cube trays or other container, add the sticks* and you’re done!
Use frozen grapes to keep your glass of wine cold without watering it down!
Red grapes have more nutritional benefits and freeze better than green, though some people do prefer the green ones frozen. Try both.
Skip the wax paper (be green) and the cookie sheet. Just shake well to get nearly dry and put in resealable bag. Lay flat in freezer so they don’t bunch and are 1-2 deep. They freeze fine like this.
If you want to make grape Italian ice, just puree a bowl of grapes, then freeze it for a few hours.
Do not feed these to small children, as grapes can be easy to choke on if not sufficiently chewed before swallowing.
