Traditionally beer is served in a Maß: a beer glass that holds one litre. By law, only beer brewed in Munich may be served: Paulaner, Hacker-Pschorr, Augustiner, Spaten, Hofbräu München and Löwenbräu.
The first Oktoberfest was held in 1810 to celebrate the marriage between Princess Therese of Saxe-Hildburghausen and Crown Prince Ludwig of Bavaria. It starts traditionally after the 15th of September and runs until the first Sunday of October.
