History In Bavaria in the year 1553, Duke Albrecht V created a law stating that brewers were only allowed to make beer between St. Michael's Day (September 29) and St. George's Day (April 23). To have a beer to consume throughout the Summer months, a strong lager was developed and brewed in March (März). This beer was brewed from a stronger extract, resulting in a higher alcohol content, to extend its shelf-life.
