I could google it, but what exactly is the Bavarian Purity Law?  Ive brewed my own stouts, lagers, pale ales - not familiar with this term oddly enough!

@Tristerin it says that only a selected variety of ingredients are allowed to be used for brewing beer. 

Edit: it's hops, malt, yeast and water btw. 

@DildorTheDecent if I didn't hate beer so much I'd say something like "AH! some good ol' Franziskaner! Lecker! "
