Crispy-Bready-Dry: Zwickel is pronounce "tzvickle", and is named for the sampling cock attached to the outside of a fermentation vessel. This unfiltered offering is a mild, effervescent form of Kellerbier, meaning "cellar beer" in German. The term applies more to the method of serving beer directly from the lagering tank than it does to the specific beer style. Red Rock Brewery's Zwickelbier, however, can be the best thought of as an unfiltered Pilsner.
