I've recently opened a brewery where our primary focus is our tasting room that is supplied from serving tanks direct to our taps. I've run breweries before but this is my first experience with serving tanks and there is not a lot of local breweries using this system so its been difficult to get info. Basically when we pour from our taps it will pour fine for awhile and then surge with foam, which makes me think perhaps the co2 is "breaking out" like when your psi isn't high enough. What I don't understand is we use beer pumps to supply the beer to the taps. Head pressure on the tanks is individually set (with CO2) for equilibrium based on the particular beer temp and co2 volumes. Talking to my draughtline guy he says this shouldn't effect the beer dispense as this just maintains the carbonation, it is the pumps that supply the beer to the taps, but he is stumped as to the problem. The pumps are run by our air compressor (this air doesn't come into contact with the beer) and I'm wondering if the pressure the pumps supply or the length of the lines could be wrong. Not sure if a counter-pressure system of filling growlers would help as it wouldn't be practical with our setup and the problem occurs pouring pints as well anyways. Has anyone experienced anything similar to this or have any insight to a solution? If it is a problem with the pressure the pumps are running at I can start researching how to adjust them but wanted to ask Probrewer first.
Thanks,
