Oktoberfest 2015: No beer without patents

On the busiest days, bartenders at the Munich Oktoberfest serve up to 70 000 litres of beer – all in record time. Thanks to modern technology, the beer keeps flowing and never peters out during the festival's 16-day run. But without inventors and their inventions, none of this would be possible. So what are these inventions and where can they be found? This year again we put the Oktoberfest under the microscope.
