We wont see another crop like this years for a few seasons - best if you can bag up what you can this year and freeze as pulp ,blanched slices or stewed ,whatever .You should be able to pick up some bargains of tail end stuff if you go and speak in person to wholesalers or market stalls .They dont have the time to sort through the stuff so will condemn whole trays or even boxes if more than a certain amount appear below par .Sunday closing time is always a good one for markets as they have to consider what will last until the next market day .If you dont mind taking a load of duff stuff you can really do well ,but you have to take the good with the bad and take what you are given with a smile .If you feel that they are extracting the juice by offloading all their crap on you then look happy but dont go back. Given that you will get a mix of whats in stock you could make some nice blend up - when you get outside specific cider apples it sometimes is hard to get a good all rounder so blends of cookers and eaters work nicely.
Still ,even if one misses all of this seasons bounty much of the excess will have been made into concentrate apple juice anyway and as the stalwarts have already mentioned many a good brew can be made from supermarket juices !
