Sorry, got off topic.
An organic beer, if I were making an organic beer then I would probably use natural spring water or something that doesn't have man added chemicals like fluoride or chlorine. Because whether fluoride is good or bad unless its natural in the spring water its not really organic even tho the ions are the same. I have not thought too much about it, our water is screened and chlorinated and comes out the tap. It is also true that people worry about many small things like a brass spigot or aluminum pots which may possibly not even be as bad as fluoride, I don't know. But I am starting to figure out why its not discussed very often.
