Hello Muc
You can store apples wrapped in newspaper seperately, then stored on lats, like the old
shelfs that you used to have in airing cupboards (Hot Presses).
You can buy units but they are easy to make out of 2 by one. Ours is about five feet high
and has roughly 8 trays in it.
You can store other vegetables as well - the shelving has to be kept in a dry, airy room, damp
will spoil the apples. We used to keep ours in a large porch area that was open to one side all the time.
You could also core the apples, and chop them into slices, and dry them in the oven, or above an Aga.
Google drying apples or preserving food. I have a good book on this but just can't put my hand on it
at the moment
