Beer line length.....
« on: February 16, 2011, 01:13:21 PM »
OK, some learning needs to take place here.....

I know that beer line has a small ID to provide counter pressure and control foaming. But, I was reading that it keeps the beer from foaming as it enters the line..... As long as the beer is "solid" throughout the line, is the line length correct, or does it STILL matter how long the line is.....?

I have no foam in the lines, but am still getting a bit too much at the tap. Lines vary between 4 and 9 feet..... I can try a 12, but does it make a difference if there's no foaming in the line?

Trying to get my head around the physics here....

Yes, it makes a difference when it comes out at the faucet end.  Longer lines provide more resistance, and you need enough resistance for your serving PSI to prevent foaming when you pour.

Your best bet is 3/16"ID X 6ft long. The key is a cold faucet and regulated pressure (12-15psi). The first beer will foam a bit because the faucet is warm but each pour after that within a minute or two of each other will be perfect.

You should also carbonate at the same pressure you plan on serving.  Although you can turn down the pressure for serving, after a few days CO2 will start to come out of solution.  If you crank up the pressure and shake, you could be overcarbonating, so I'd stop doing that at least until you figure out what your problem is.

Picnic faucet or regular beer faucet?
What temperature and CO2 pressure is it set at? How long has it been carbonating?

Here's the Brewers Association Draught Beer Manual that has more info than you'll ever need.

Regular beer faucets in keggerator door, long shanks, nice and cool.

OK, here's the MO......

I chill the keg to 42º ish, then force carbonate at 30 psi for a few minutes, then I put a gauge on the keg and let it settle, repeat as necessary 'till it balances at 10psi.

I think my lines are too short. I will get a really long line (like 12 feet) and see what that does.

OK, I read this on my phone while waiting for my kids and before heading to the hardware store to get line for a picnic tap.  I got 3/16 ID vinyl line but I don't know what constitutes "Beer Line".  This is pretty thin stuff.  Probably 5/16 OD.  The line I took off seems to be a lot thicker walled.  Not sure where I'd find beer hose if there's a difference.  Just wasn't sure since all I have is picnic tap.
BTW, I have 10 feet of this on the tap right now and it pours great.

Reading the subject title, I thought you guys were talking about the concession stand at the ballgame.   :-[

Which is usually proportional to the line at the urinals.

Don't waste your money.

Here's a great resource.

Drag on 3/16 tubing is 3 psi / ft (that is what I heard).
If you have 5 ft tubing it should be 5 X 3 = 15 or 5 ft of tubing should handle 15 psi in your keg.
