On Saturday (tomorrow), one of the more distinctive events in the annual beer calendar visits Oregon: Zwickelmania. It is the day when you are invited to mosey around the innards of breweries, partaking here and there of beer pulled straight from the tank (zwickel [v]: when a brewer sprays himself with beer from a conditioning tank in an attempt to fill a small container with a few ounces of fresh, fresh beer). If you love beer, you should try to get inside as many breweries as you can, because for some reason it is fantastically entertaining inside them. Ask questions, too, for the answers are always interesting and usually surprising. And no beer tastes better than beer straight from a tank.
