I got this tip from Ben Clark at Clarkdale Fruit Farms, and it solved a problem too frequently occurring in our house--we would buy a gallon of apple cider but drink it too slowly, only to open the fridge one day and discover that the jug looked ready to explode. But it turns out cider freezes beautifully and easily, so you can pour out part of the gallon into another container for the fridge and freeze the rest of it. Be sure to leave generous head space in whatever container you freeze it in, as cider will expand when frozen just like water. At this time of year, you can even save a little energy by freezing it outdoors, then putting it in the freezer. Let it thaw in the fridge, and be sure to let it thaw completely, then shake or stir, before drinking.
Why bring this up now? Well, Clarkdale is closing for the season this weekend, so if you love their cider like we do, now would be a good time to buy a couple gallons to freeze and drink for the rest of the winter. Enjoy!
