In Germany, this special seasonal beer was called Marzen (March) for the month in which it was brewed. When brewing resumed again in the fall, the remaining stock of Marzen was brought out for the Octoberfest. In this way, a single style of beer came to be known by two names. Like the Octoberfest Marzen of German tradition, ours is brewed once a year, and generally comes on tap mid-October.
