Hi smokey,
Hefe Weizen is very special and only brewed in Germany.
In Germany is brewing beer a very serious thing.
It´s forbidden by law to use any chemicals.
Only three things are alowed to use, that´s hops, malt and water.
The rule after that beer must be brewed is still from 1516!
It´s the "Reinheitsgebot" (translated as "purity requirements").
The first Reinheitsgebot is from 974!
After that several followed.
But that from 1516 was then the one who is still in order.
The EC doesn´t like the German solo attempt in beer and wants to cancel it. But till now they fortunately didn´t.
I know only one beer, that you can compare to the German, and that´s the Belgian.
But take care, it´s strong.
