Bavaria passed a law for inns and shops
That beer, except for yeast, be only brewed
With water and barley and hops.*
*It was called "The Reinheitsgebot" or "German Purity Law". The original impetus behind the law was rising prices in wheat and rye, which were causing bread prices to spike. By limiting brewers to barley the demand for wheat and rye plunged whose domino effect was a drop in the price of bread. This may be a good opportunity to recommend the German beer, cuisine, and ambiance of the wonderful Frankfort restaurant Chef Klaus' Bier Stube. The wienerschnitzel melts in your mouth. Guten appetit!
That's the incomparable versatile entertainer Peter at Chef Klaus' Bier Stube in Frankfort, Ill.
