Got to a local orchard if you have one and see if they have any rotton apples. normally they will give you a whole bin for free. Which is like i dont know how many bushels. probley at least over 12.

But there the apples that are not good enough to sell and still not good enough to go for cider apples.

But trust me just go ask any orchard and see. Like i work on an orchard and we normally have a few bins ready to go.
