keuren, you are onto something good. Gelatin, cold, and lots of racking has worked well for me. You still need to be very careful if bottling to avoid explosions. But if you're going to keg it, there should be less worries. The thing is, patience is still required. If you rush your cider, it will be like a tart fart bomb. But if you can leave your cider alone in the fermenter in the cold for a few months, your patience will be rewarded with a naturally sweet cider like you say.
