Preserve cider: simply pour off enough from the plastic jug to allow for expansion and to put it in the freezer.  It will keep almost indefinitely and keeps longer after being thawed than it would have  kept originally.  It can also be heated to boiling and sealed in clean jars or jugs.  We've had good luck with Mason jars and with any gallon or half gallon glass jug with a metal lid and a plastic seal.  (Heat the jar by running hot tap water over it, then pour the hot cider into it and screw on the lid. You'll see the lid depress and seal as the cider cools.)  Cider is a great natural drink, cold or hot.  You can mix it with cranberry juice and make your own cranapple juice.  Kids love icy apple slush.  Freeze the cider in the jug and allow it to half thaw then shake it up vigorously and pour out the icy cold slush.  Various mixes for making hot mulled cider are sold or you can make your own.  Cinnamon stick and allspice are good.  Also, adding cider is the real secret to making a juicy apple pie from fresh apples.
