A company called Bottoms Up Beer designed a beer dispenser that fills up cups from the bottom. Presumably the dispenser opens and then closes a perforated hole in the bottom of the cup. Or it’s magic!
It has to be a one way valve of some sort in the bottom of the cup that marries up with the line that the beer flows through to fill the cup. I heard a distinct snapping sound when the cups were seated into the dispenser on the video. What a concept. No extra head on the beer, no spilled waste over the brim of the cup, a defined volume dispensed each time - certainly more cost effective from that aspect than a traditional tap. Would indeed work great for venues such as the Pepsi Center, Invesco, Coors Field or a dance club, but I would think it would have a limited application for bars and restaurants where the beer is served in a glass or mug. Kinda cool to watch it fill the cup up though.
