I just got a new draught system installed at work. It's a glycol system with 32 feet of line. It also has pumps to help push the beer through. Some of the beer has been coming out foamy while trying to pour a growler. Should I increase the psi or decrease it? We are just using a standard faucet. Thanks in advance.
Way to little info to tell where your individual pressures for every beer needs to be. Is it a growler only problem? If not then Since your a commercial establishment get your distributor back in there to dial in there products properly. Last thing they like to see is there products not being dispensed correctly.
Need more info. How are you filling the growlers? How many lines? Are they all foamy? Are there regulators for each line? If the system was just installed, I feel the installer should make any necessary adjustments to get your system balanced. But if you are only having problems with growlers, my guess would be it has something to do with how you are filling them. Are you bottom-filling them? Do you have some kind of counter pressure setup?
growlers will be foam more often than not even on well designed systems. do your pints pour perfect? I mean spot on, every time. first glass of the day included? do not adjust the dispense pressure. it will only give you additional headaches. adjusting the pressure without knowing the details of your own system is like driving blind folded. it will certainly change your location but the result is always catastrophic. you can improve the pouring of growlers with a dedicated growler filler, but those are clumsy and really not practical in a bar. a well chilled growler will help. rinsing with cold water to chill the glass is about the best you can do. that and take some time to allow the foam to settle. check the temp of your beer in the glass. it should match your cold room to within two degrees or so. it should be between 38 and 42, usually. if these temps are off you have to address the temp of your beer in the cooler, in the lines or both. with some other useful info we can get you to being an expert in your own system, as you should be. what gas blend are you using? what diameter line? what is the vertical difference from keg to faucet? you shouldn't need pumps with 32' of line if installed properly. did the installer explain the reason for pumps? Cheers.
