"Aecht Schlenkerla Rauchbier Urbock is unpasteurized. Fuller and richer in body than the Maerzen, it uses more malt and is matured at least one month longer. 1,805 lbs. of smoked malt is swallowed up in one batch. It is brewed only once a year for the Urbock-celebration at the Schlenkerla tavern in Bamberg in early October."
