The biggest contributor to the amount of foam is the flow rate out of the tap. To reduce the foam, reduce the flow rate. You're using 11 PSI with a 5 ft line, which sounds like it would pour really fast.

Option 1: Lower pressure for serving

Bleed pressure from keg and set regulator to 2-5 PSI when serving. Re-pressurize when not serving so the beer doesn't go flat.

Pros: No extra equipment required.

Cons: Incredibly wasteful in terms of CO2. Using this method, I blasted through roughly a third of a 5# tank dispensing just one keg.

Option 2: Adjust beer line length

Make the line length longer according to the style of beer, to compensate for high pressure in the keg. This has to do with fluid dynamics. There is info available on this if you search; I remember seeing posts on this a few weeks ago.

Pros: simple, effective, and inexpensive

Cons: Requires a lot of cutting and re-clamping of beer lines for each different style of beer; no way of doing fine tuning of flow rate for more or less head; requires keeping a bigger inventory of tubing for different styles.

Option 3: Flow control

Put something in your draft system that allows you to adjust the flow rate without attaching/reattaching anything.

Pros: easy to control, less hassle/mess. Just turn a dial and get the flow rate exactly what you want it to be, to perform on-the-spot adjustments for the perfect pour.

Cons: more expensive, although I've seen plastic inline flow controllers like this $2.50 USD one

I have the Perlick 650SS tap on my kegerator and it works like a charm. If you're using a picnic tap or want to use a tap without built-in flow control, and you want something nice, you can get an inline flow control compensator like the one made by CM Becker, or (less expensive but still solid) make one using a stainless steel NPT ball valve and two hose barbs (clamps and plumber's tape not included).

I ended up ordering this SS b/v. Seems like it should work with the correct nipples right? Also, how do you compress the actuator on the can tapper npt connection? Rip it out? Thanks for your help
