Too short or too long?

Brewing Processes

I am getting excessive foam from two of my taps. I know that the first pour will be foamy because of the tap being warm, but after that it should be a good pour.
I am away from my reference material and am having a brain fart. Is excess foam from too short or too long a line?

Thanks!

Too short.  You need more line to drop more pressure.

If you’re pouring from a cobra tap, you can raise the height of the tap and it will do the same thing.  Or you can bend/restrict the line.  Anything to give it more resistance.

I find that 6 feet of 3/16" ID tubing with a picnic tap helps reduce foaming. Creating resistance (slowing the beer down) to flow reduces foam formation.

Thanks! I am heading to the LHBS tonight so I will pick up more line.

No cobra tap, Perilicks all the way!  :smiley:

Have a great day!
