Today’s beer video, in honor of it being Sour Sunday, is a film of a talk given by Jeff Clawson, who’s the Pilot Brewery Manager at Oregon State University’s Food Science & Technology Department. In the 23-minute video, Clawson “discusses a recent study on sour beers at a Science Pub event at the Calapooia Brewery in Albany, Oregon. OSU is one of the world’s leaders in research on hops and the brewing sciences, and many graduates of the fermentation sciences programs go on to have a huge impact in the industry.”
