All foam.

The line to the spigot is not foam.

Heres how this came about...

Kegged & hooked to co2, set to 30psi.
left in fridge at that pressure, hooked up to co2, for 2 days.

unhooked, released pressure, reconnected at 12psi in the fridge.

waited 1 day.

served up these foam glasses.

will this dissipate, any ideas, insights?

the beer is delicious and carbonated enough for an oatmeal stout, awesome batch in fact, but i need to wait 5 min for the foam to go down.

1 foot long bev line. whatever the standard size is for a plastic spigot... something like 1/4" i think

That is way short. Average is around 5-6 feet from what I recall.

my old bev line was 3 feet, and then i read online that having it that long just makes it more likely to get caught on stuff or under the keg. it matters how long the line is? this doesn't make physical sense.

Your system needs to be balanced-- the rapid decrease in pressure over a one foot length means that a lot of CO2 will come out of solution. Longer lines are needed to provide enough restriction to balance the pressure inside the keg and in your beer.

If you lower the pressure in the keg, I bet your beer will pour a lot better with the short line.

Also, it's possible you are overcarbonated with 30psi on the beer at refrigerator temps for two days.

Most line is 3/16". It makes sense how long the line is when you think about it- the short lines cause foaming. It's all physics- the amount of resistance vs. the amount of pressure.

To test our theory of your short line being the problem, try this:

Purge the keg. Reset at 1-2 psi, just enough to push the beer out. See if there is any foam.

Here's some good info: Draft system line balancing

5' minimum, 8' recommended by me 3/16" ID beer line otherwise foam city, 1/4" ID line will be foam city as well, unless you dispense like Yooper said at a couple PSI. But that's a PITA to be bleeding and wasting CO2 all the time, just get longer lines or look up cure for your short hose troubles where some people have added resistance inside the keg.
