If you have a Kenwood Chef, then this attachment will do a job of juicing apples.

You are being daft, from someone who had made cider. The Kenwood mixer would break under the strain of so many apples. A dustbin not a demi-john as there is lots and lots of apple gunge for the compost. Can decant to a demi-john later. Do not use a fermentation lock, cotton wool at most.
It is not worth the effort. Type of real apples doesn't matter for taste. Not sure about the juices. Sugar makes it expensive.
