debeer1-8, Exercise 1: Serving and opening Model answer: Only Munich breweries may supply the main tents: Augustiner, Hacker-Pschorr, Hofbräu, Löwenbräu, Paulaner and Spaten. They serve a special Festbier, a little stronger than ordinary Helles (about 6 per cent), in a one-litre glass mug called a Maß. The festival opens on the first Saturday with a parade of landlords and brewery wagons; at noon in the Schottenhamel tent the mayor of Munich taps the first barrel with a wooden mallet and calls out "O'zapft is!" (It's tapped!). Beer is then served in all the tents.
