A friend of mine and I want to start producing cider, but from scratch: He inherited a property which we want to clear up, plant apple trees and eventually produce apple wine (a common beverage in some regions of Germany). We are aware that this is a 10+ year project.
I'm a biologist, so I know the basics, but I don't know much about agriculture. I'm looking for literature on how to select, plant and maintain apple trees (the wine-making part is not relevant at this point). A general agriculture book will also do for now. The literature doesn't have to be easy, I'm completely ok with research papers or university-grade books.
