so what's wrong with using ascorbic acid? because i was at the super wal mart store, and they have 100% apple juice that's from concentrate, and the only other ingredient is Ascorbic acid. the juice is crystal clear, and it's only $1.97 for a 3 quart plastic bottle. i've heard that preservatives are bad, but i don't quite understand what a single vitamin used as a preservative would be horrible. Can a genius fill me in?
