As human civilization has developed, beer has been there right along for the ride (still, don't drink and drive). It's been used as everything from currency to inspiration for further innovations (like math and medicine). And when we didn't know the first thing about germs, the alcohol in beer protected us from drinking harmful bacteria by killing it off. Here, we discuss a documentary about beer's place in human history — a quenching draught to slake your thirst for knowledge! Cheers!
