Ok so i'm about to get two apple trees specifically for homemade cider brewing. I know to clean your materials well, but is there any kind of natural yeasts that can grow to make you sick? Also should I pastuerize the pressed apples before beginning fermentation. Should I add sugar? I want to just use the natural yeasts inside of it to see what a wild grown cider is like. Also how could I get a decent gravity in this. Sorry about all the questions but i'm extremely new!
