Not sure how to explain this, but here goes. My keg is a torpedo keg, and the pressure is set to about 10psi on the output. the fridge itself is sitting at about 30 degrees on the inside, might even be a bit colder. The beer line is runs from the tap, thru the freezer compartment, up the tower and out the tap. I put a foam insulation in the tower similar to the stuff you use to wrap pipes outside to keep them insulated. Random pours seem to produce a lot of foam, and some are quite normal in my mind. I tilt the glass at a 45 degree angle to start the pour but that does not seem to help. I have read that the line is warm going up the tower and that is what is causing it to foam up, but with the insulation would that still be the issue? It is not really bad, maybe 1/3 of the glass or so on it's worst, but annoying at times.
Thanks for the help.
