Whatever. I think the real thanks goes to Medieval German monks for their contributions to the development of real good beer.
The cave was the perfect place to brew German-style beer. In fact, we owe beer consumption for modern refrigeration — the Germans’ caves used to brew beer were of limited size, and a rising population drank up everything brewed during the winter before summer got underway. What a breakthrough that was. Of course, they still wound up starting two world wars...
