So, I've got it in my head that I want to try to make a wild/sour/spontaneous cider. From what I've read, some folks on here use wood chips/cubes in secondary for their sour beers.
I have an apple tree here at home that needs pruning. If I chop off a section and cube it up, could I add it to a cider and eventually end up with a sour cider, due to microorganisms in the wood? I assume they would have to be left alone, ie. unsanitized for this to work.
