It’s billed as the world’s fastest beer dispensing system, and it’s coming to Wells Fargo Arena. The Bottoms Up Draft Beer Dispensing System will debut tomorrow during the Iowa Energy game, arena officials announced.  The system, which dispenses beer through the bottom of the cup by using a magnet that returns to the cup’s bottom once it’s filled, can fill glasses up to nine times faster than traditional taps. The Bottoms Up tap will be located on the main concourse of the arena outside of section 104.  Iowa Events Center General Manager Matt Homan said he hopes to expand the technology to other areas of the venue once the initial tap is up and running.
