(1) Beer shall be brewed from malt or a malt substitute, which only includes rice, grain of any kind, bean, glucose, sugar, and molasses. Honey, fruit, fruit juices, fruit concentrate, herbs, spices, and other food materials may be used as adjuncts in fermenting beer;
(2) Flavor and other nonbeverage ingredients containing alcohol may be used in producing beer, but may contribute to no more than forty-nine percent of the overall alcohol content of the finished beer.

Guessing that hard cider was a bad idea! Crazy stuff. Anyway are stats like this common in other states? I know of the German law, but would have never guessed one existed in MO.
