The Oktoberfest goes for 16 days, 12,5 hours a day and around 8 mil.Maß (liters) of beer are drunk: thus, at the Oktoberfest, every single second 11 Maß are drawn (!!!)
The patented turbo tapping technology allows for drawing about 1 Maß every 3 to 5 seconds. This means that, in principle, about 60 “Turbotappers” would be more than enough to draw beer at the Oktoberfest!
P.S. According to the EPO, up to 2015 there were 1813 European patents for Beer taps.
P.P.S. During the time you spent reading this, ca. 330 Maß were drawn at the Oktoberfest!
