HAHA! They're all made out of corn. I always wondered what that crap was made out of. Now I know why they can't be sold under the label of "beer" in some countries.
Not just corn.... Barley, hops, wheat and other grains.
That website did crack me up where they stated that there may be grain in the beer..... Worse, some beers may cause vegans to violate their diet. God forbid! Suicide watch!
These paranoid folks are frightened by caramel coloring, GMO corn, propylene glycol (could be a health issue, but probably not), corn syrup and God knows what else. They are into organics. What they don't realize is that organic foods reflect what is in the soil and water... Not using pesticides and fertilizers does not mean that the veggies and fruit don't contain chemicals or other non-organic substances.
