Default Kegerator Foam

Afternoon everyone,

Have a Kegerator shooting out too much foam on usually after 1-2 first pours of the day minimum (used daily) then 1/3 foam per pint afterwards, which is still excessive.

It's a wheat beer running about a 5-7 psi as 8-10 shoots it out too fast/too much foam.

As I'm trying to isolate the problem, I noticed that when it's foaming, it's pouring in a circle rather than a stream. To explain it better, the beer is coming out around the edges of the spout with seemingly air in the middle (hence it's a circle) and as soon as it hits the chilled or unchilled glass, it starts to foam up shortly thereafter. Beer lines appear completely clean from the outside, but I was going to change them anyway in the next few weeks just to take that off the list of possible causes.

I know how to pour, I know how to open the handle all the way, etc....so it's not seemingly the pour that is the problem....I simply can't figure out why sometimes it pours in a circle and sometimes it comes out in a nice stream with minimal foam.

Any ideas?

Thanks in advance

How long are your beer out tubes? They need to be at least 10' long. That will solves most problems.

No clue about the circle versus stream issue. What length are your beer lines? A lot of times increasing the length of your lines can fix the foam problem. A pretty standard length to try is 10 ft.

You might also want to look into cooling your tower. This won't cure the overall foam problem but it'll help with the first couple pours. You can do several things. I built a makeshift blower out of a pc cooling, a project box, and some tubing to blow cold air from the kegerator into the tower. Used this website for reference. http://www.kegkits.com/kegerator5.htm I've seen others install a couple pieces of copper tubing extending from their tower into the kegerator. Either way works.

First, the responses are greatly appreciated, thank you.

Second, really 10 feet? I'm about to measure it right now but I'd imagine it is half that. I'll post again with measurements.

3 ft in kegerator plus 1 foot tower (not sure if it extends all the way in the tower).

That is your problem. You need to use at least 10ft of 3/16" beer line.

OR drop an epoxy mixer stick in the beer out side of the keg. This adds enough resistance to mirror longer lines. My beer lines area 17" with no issues and I serve at 9-11 psi

Good luck

Thanks everyone and thanks Rick for the stick idea. I might have to try that pending how things go.

I am getting the beer line in shortly and will give it a go in a week or so. I'll update accordingly whether it's a success or not.

Again, much appreciated.

Mike

Beer Lines now at 10 feet as of today. Early pouring seems like it remedied the problem, but it's mostly untested right now. Will test it out this weekend and give feedback, but I think good odds we found our problem.

Once again, thank you very much everyone. I would never have guessed 10 feet was the problem.

After testing out the lines for a while (10 ft at 3/16") and keeping anywhere between 5-8psi, it appears still more foam than we should be having. Less than before, but still wasting more than we should unless it's pour after pour after pour where it finally gets flowing right.
