another foamy beer question

[oldstyle69]

issue: lots of foam (even with low 3psi serving pressure), 15 min after pour. ive only had this problem with my sanke connection. ball and pin locks pour fine.

ive noticed after a few min, the bev line starts to get bubbles in the first curve of the line. so when i pour, i get good beer, then a big glub of foam and then more beer.

beer lines are just over 8' long on all kegs.

what gives? is this a temp issues, with it not being cold enough to hold CO2 in soultion or what ever(i read that some where)...its currently at 3C or 37F

A couple options: 1) increase the length of your beer lines, 2) try smaller inside diameter beer lines. The problem appears to be that there's not enough resistance in the beer lines, as I understand it

 

[thereverendmaynard]

I went from ~5ft to 11ft lines. Went from full glass of foam on first pour to perfect pours every time.

the lines i have are bev lines, im not sure i can get them any smaller and still have them fit over the barb connections, but longer lines are def doable.

3psi is your problem. How many Volumes of Co2 is the keg carbed to? . If temp is to high and pressure is to low gas will come out of suspension and you get gas bubbles in the beer line. If your system is not balanced it doesn’t matter if you have 5 feet or 50 feet of line co2 will come out of suspension. Use this chart to set psi to temp.

These are the threads that drive me insane.I mean no disrespect to the forum but outdated old school technology advice is the reason the OP is having issues in the first place.
Longer lines/balancing and all that will work but take a lot of trial and error.Brewing methods are being debunked things are changing yet EVERYONE recommends longer lines ALWAYS.Brewers will spend hundreds if not thousands on there systems,3 tier,pumps,stainless brew tables you name it..YET..The only thing a kegger needs is a flow control faucet and the 5 ft lines the tower came with and ALL there issues will disappear yet no one ever recommends them from the getgo..Figuring things out are interesting and fun..fighting foamy/flat crappy pours isn't one of them...Let the bashing begin

Longer lines are a lot cheaper than flow control faucets.

It sounds more like the OP may have a temp stratification problem though. If the beer is out gassing in the tubing then it's likely that there is a temp differential between the lines and the keg.

OP: do you have a circulation fan in your kegerator/keezer? If not then adding one may help. If you do then perhaps it's not stirring the air too well, you may need to re-angle the fan(s) or make some ducts to help the cold air circulate better

This. But also planning from the beginning. I knew that I'd need ~10' lines and a fan inside my keezer to get good pours so that's what I did, worked perfect right from the beginning.

"EVERYONE recommends longer lines ALWAYS". You just recommended the same thing. "The only thing a kegger needs is a flow control faucet and the 5 ft lines". Longer lines/balancing and all that will work but take a lot of trial and error. No trial and error needed you just have to read. You could start here. http://www.mikesoltys.com/2012/09/17/determining-proper-hose-length-for-your-kegerator/
Yes these are the replies that drive me insane.

I suppose your assuming I never had longer lines,or have been through that chart,and adjusted my line length according to that chart and had a low area in the line coil and everything else that goes with long lines,and had the same issues as the OP eventually ending up with flow control,and never looked back..Theres a reason You will never find a single bad review about the flow control..they work..and there simple and not enough people recommend them.I also didn't recommend longer lines..And again for all the money spend on an entire brew system and constant upgrades and then go to kegging and not spend the extra $30 or whatever it might be for flow control is foolish..

I'm not assuming a thing. The fact is 10 ft of line is the same thing as 5 ft with flow control. You use line length to control flow. If you read my first post I did not say anything about needing longer lines. Please read past the Hose Length Calculator. http://www.mikesoltys.com/2012/09/17/determining-proper-hose-length-for-your-kegerator/

 

[JONNYROTTEN]

10 ft line is the same thing as flow control,are you sure cause I've done both. I can assure you there not the same.This is getting silly now.

I am sorry - but how is longer line with more resistance will help someone already pushing with just 3psi?! Have you ever served with 3psi and 10 foot line?

Someone please explain the physics and reasons behind it - don't just say "get longer line, it worked for me at my 12 psi serve".

There are really three, or maybe four variables here. Beer temperature. Carbonation level (depends on the carbonation pressure and temperature). And serving pressure (depends on pressure - assuming it's the same as carbonation pressure - otherwise adds another variable) - this is affected by line length/diameter = resistance.

To me it seems the beer is foamy because it is overcarbed. Bleed the pressure a few times, keep bleeding until it's very low carbonation, then carb to about 2 volumes depending on temperature and serve using the same pressure, for simplicity.

Serving overcarbed beer, regardless of beer line pressure, will result in a lot of foam coming out of the solution.

 

[PapaO]

Yes i'm sure. The word flow in flow control means to control the flow. You can do the samething with line lenght so with your 70$ flow control faucet I get the same pour with 10 ft beer line for 5$. Now thats silly.

 

[oldstyle69]

thanks everyone. didnt mean to stir the hornets nest. but its all interesting to me. ... my fan crapped out a year ago, but i only recently had this issue. the temp of the Keezer has been set the same.

i def could have over carbed, as i ran out of CO2 on the second day and had to refill and reset everything up. i will end up getting a new fan hooked up, but that shouldnt be to big of a deal, if im pushing differernt beer, thru diff kegs, all with the same length of hose with no issues. ill dump the kegged co2 and recarb. seems to be a quick fix. tho i had this issue with a commercial keg and was pushing at 5psi and still did the same thing.

 

[oldstyle69]

i may have had it set to 20psi for a few days after i got the new tank hooked up. that would have pushed my co2 lvls up over 3 for sure.

 

[Pappers_]

OP got a few answers. Closing it.
