A good conspiracy is that commercial beers are bad for you as they have "heaps" of chemicals in them.
I really dont know how to reply to these charges.
Heaps of chemicals is an astounding claim.
Huge macro-brewers use hop extracts (some which have been chemically-altered to prevent skunking) and fermentable adjuncts like rice and corn, that's about it, really.
Beer is its own preservative. The alcohol, low pH, and iso-alpha acids from the hops prevent anything real bad from growing in there.
