Beer that’s flowing too quickly will cause too much gas to break out in the glass when you’re pouring it. This wastes beer, which wastes money. It’ll look something like this when you try to pour a pint 👇🏼

Target flow rate for almost all draught beer is 2 ounces per second. This optimizes the amount of foam on top and means it’s not taking forever to pour the beer.

The reason it’s flowing too quickly is pretty obvious: The gas pressure is too high, and it’s pushing the beer too quickly out of the keg. Here’s what to do:

  1. For a long draw system, go to the secondary gas regulator (this is the regulator inside the coldbox) and adjust the PSI down a couple points. Most mixed-gas long-draw systems should be happy with a PSI from 22-30, depending on the length of the draw from the keg to the draught tower. Remember, you’re looking for two ounces per second flow rate.

  2. For a direct draw system (kegerator, etc), adjust the PSI down a few points. Most 100% CO2 direct-draw systems should be happy with a PSI from 10-12, depending on the length of the draw from the keg to the draught tower. Remember, you’re looking for two ounces per second flow rate.
