Keg Foaming Question

[Yontsey]

I have a keg from a local brewery that I keg a little bit of over foam when I pour. It's a NEIPA. I'm keeping it at around 41-42˚ and I have the CO2 at 12psi. It's the D-Style coupler so the liquid comes in from the top. There's a couple inch stretch where the line comes from down the tap neck and then loops back up to the coupler where there's no liquid. I don't know if that's why it's foaming or not. Just an observation. Would it need more CO2 to compensate for that gap?

Try getting the keg down to 38 degrees, or reducing your pressure to 8 PSI. If you've just moved the keg, it may need to sit overnight as well for the foam inside the keg to die down. Also make sure the connections on your sanke coupler are tight. Once it's pouring correctly there shouldn't be any gaps in the beer line

Roger that. The gap is what concerned me. I’ll adjust it in a few minutes. It’s sat over night and will sit another 10 hours or so until I pour again so that should give it ample time to settle.

Was gonna say this too. Cool it down to 38F and turn down pressure.

Line length can be important too

Between going from my regulator to the manifold to the keg I’d say there’s 6-7’ of line

I was under the impression you wanted an IPA to be around 42-46° no?

If that's the serving temp that you'd prefer, then you'll have to reduce serving pressure. The industry standard is 38 degrees, 12 psi, with 5 ft of 3/16" ID beer line. The length of gas line does not matter, just the liquid line. You can adjust any of those to your preference, but will need to change the others to keep your balance. 6-7' is a good length of line (some people insist on at least 10 ft, which is unnecessary in my professional opinion).

I often serve beer at home at 8-10 psi and it works just fine. You may need to run a few pints through until you're getting the pour right and the gaps in your line are gone.

Sounds good. I reduced it to 38. Before I was keeping them between 39-41. It’s on my patio so it fluctuates with the outdoor heat. Gas line is probably closer to 7-8’ so that should be good. I’ll reduce the psi and have a few pints later….for science. Thanks guys.

You're welcome! Post a picture of your pint and show off your perfect pour

To drink it yes, to pour, the cooler it is, the less likely you will get foam. That is universal for any beer.

Look into eva barrier line too. I switched to that and rarely have foaming issues and my beer lines are only 3ft long

I know you use taps, so what diameter line and dispensing pressure? I am tiring of releasing pressure to pour.

I use the eva barrier 4mm line. I serve at whatever pressure is required to keep the beer carbed. Currently i have an esb Being served at 18psi. I always pour a 1-2oz pour first to clear the lines, after that it is foam free. (Mostly cause i am not a bar and the lines outside the kegerator warm up. )

One thing to note, you will need to replace your tail pieces since the eva line is a push-connect style line

My gas lines are the Eva barrier 5mm x 8mm lines. I use the duo tight quick connects as well. They've worked really well.

Beer lines are Eva barrier that came with the Komos kegerator I got. Those are 4mm x 8mm. Those are 5', give or take.

I just need to get my shit dialed in. I have a draft tower sleeve but I forgot to put it on when I was assembling the tower and it was a pain in the ass so I never got around to putting it on.
