Oh, and bottle bombs... I had some cider that didn't pasteurize. My fiance noticed before they started blowing up (one was hissing). I dumped them all, but decided I would do one of the dumbest things of my life. I went out back, shook one up, and the second my bottle opener hit the cap it ripped the neck off, sending it flying 20 feet across the yard. Needless to say, justifying a keg setup wasn't very hard after that.
