I'm drinking a Julius Echter Hefe-WEiss Premium. It's a Bavarian ale. I love that so many of these German beers state that they are brewed in accordance with the German Purity Law of 1516. In the US a purity law would mean that there's a limit on the amount of rat feces, spiders, and foreign objects that can be in food for it to still be considered fit for human consumption. In Germany, this Purity Law originated in Ingolstadt and sets standards for the sale and composition of beer. Not food in general - just beer. One of the many reasons that you just have to love the Germans.
It not only gave a list of what could and could not be in beer, but it set the price of it as well. Despite wheat not being listed in the ingredients, most of the German wheat beers I've had have claimed to be brewed in accordance with the German purity law of 1516.
The kind of pride you have to have in what you produce to adhere to a law that old and that, to be honest, out of date... I envy that level of traditionalism. Take it or leave it... it's still present. We don't even get the choice here.
