What is the name of the sticker that is put on German beer that conforms to the original beer recipe?

I remember when I was there they had a sticker to show that a beer conformed to a certain quality standard and was fit to call itself beer. What is the name of that sticker and where can I find some info about it?

The Reinheitsgebot (literally "purity order"), sometimes called the "German Beer Purity Law" or the "Bavarian Purity Law" in English, is a regulation concerning the production of beer in Germany. In the original text, the only ingredients that could be used in the production of beer were water, barley, and hops.


After its discovery, yeast became the fourth legal ingredient, though for top-fermenting beers the use of sugar is also permitted. In part because of this law (which since 1988 has not applied to imported beer, but is still compulsory for German brewers), beers from Germany have a reputation for high quality.


The law originated in the city of Ingolstadt in the duchy of Bavaria on 23 April 1516, although first put forward in 1487,[5] concerning standards for the sale and composition of beer. Before its official repeal in 1987, it was the oldest food quality regulation in the world.
Reply:It has nothing to do with the original beer recipe. It is a law for German brewers, end of story.
