Bock is a strong lager of German origin. Several substyles exist, including maibock (helles bock, heller bock), a paler, more hopped version generally made for consumption at spring festivals; doppelbock (double bock), a stronger and maltier version; and eisbock, a much stronger version made by partially freezing the beer and removing the ice that forms.
