At the Munich Oktoberfest, inspectors from the city’s district administration office check the beer every day, taking samples in every tent. At least four minutes must pass between pouring and measuring, so that the foam can settle. A shortfall of up to 15 millimeters below the fill line is tolerated. In 2022 the office checked 825 one-liter mugs. Just over 31 percent were underfilled. The tent operators and the pourers are held responsible. In 2012 a consumer group, the Verein gegen betrügerisches Einschenken, the Association Against Fraudulent Pouring, demanded that the tolerance be abolished.
