127: The beer episode

P&C drink a Maibock, then discuss their favorite topic: beer.  The boys talk about hop classifications and uses, and why hops came to dominate beer. They also discuss warm vs. cold beer, and why temperature matters.  And what about sour beers? What's up with that. And speaking of off flavors, what about those beer geeks who criticize Budweiser?  They end with a pair of beer challenges.
