Bock is a strong beer in Germany, usually a dark lager. Several substyles exist, including:
- Maibock (May Bock), a paler, more hopped version generally made for consumption at spring festivals. Due to its lighter color, it is also referred to as Heller Bock; from German hell, bright, light in color;
- Doppelbock (Double Bock), a stronger and maltier version;
- Weizenbock (Wheat Bock), a version using 40–60% wheat
- Eisbock (Ice Bock), a much stronger version made by partially freezing the beer and removing the ice that forms.
