Is it a message for metrologists?
Or for folklorists?
At the Oktoberfest this year there was often very little.
According to the responsible Munich district administration department (KVR), a good 31 percent of the beer mugs examined at the Oktoberfest were found to have a tavern.
A Unterschank exists when the jug is filled to less than 15 millimeters below the calibration mark, which indicates the amount of one liter.
At the previous Oktoberfest in 2019, this was only the case for 18 percent of the rehearsals, and in 2018 for 14 percent.
For this year's controls, the KVR evaluated 825 beers.
Even the samples within the tolerance range were by no means always completely filled up to the calibration mark: the testers were only served the full liter in a good 14 percent of the samples.
This time, a beer cost between 12.60 euros and 13.80 euros – in 2019 the price was between 10.80 euros and 11.80 euros.
Compared to the "tz", which first reported on it, the landlord of the Armbrustschützenzelt, Peter Inselkammer, explained the mistake with the fact that in many cases inexperienced staff had poured the beer.
So for Bayern, the glass isn't just half empty when it's half full, but even when it's actually full.
