Now, I knew the Germans were serious about their beer. In order for it to be even called beer in Germany, it must be brewed according to the Reinheitsegot (literally, the “Bavarian Beer Purity Law”), which only allows for the three ingredients of water, hops and malt. It’s been brewed this way for centuries. Breweries started in German monasteries, back when drinking beer was safer than drinking water. The monks knew their stuff (and how to start a lucrative international business). I knew German beer was a point of pride. I just didn’t know why.
