Default Serving pressure question.

Ok, I have a keg of an ipa sitting on 10 psi of co2 for about four days now, If I turn down the pressure to say 3 psi would my beer eventually loose some carbonation?

It would once you started dispensing the beer - and thus increasing the head space. CO2 would come out of solution to balance the head space pressure with the dissolved CO2 partial pressure. So the more beer you dispense, the lower the carbonation level (given time to equalize).

This is one reason to balance a system: so the dispensing pressure is also the ideal carbonation pressure...

Chers!

Ok, so here's the problem. At 10 psi the beer comes out too fast. I'm guessing the line is to short. Would getting a longer line let the beer come out slower with out having to lower the pressure.?

Yes it would. Longer line equals more resistance to flow.

Thanks for the confirmation. Picking up longer line this weekend. How long can I expect it to take my beer to carb at 10 psi? I'm shooting for 2.3 vols at 40 degrees.

7-14 days. I think two weeks is a good rule of thumb if you carb at serving pressure. If you're hard up you can start in on it whenever you want, but you'll be happier if you wait.

Five gallons of cold beer in a corny keg at constant carbing pressure will take a bit over two weeks to fully carbonate. See this thread.

When you go for longer beer lines, get 10' or more of 3/16" ID beer tubing per faucet...

Cheers!

This^^^^^^^. Upgrading from 5ft lines to 12ft (all 3/16") balanced my 3-faucet keezer very nicely. I leave the reg set at 12psi and enjoy consistently good pours of beer/cider that I'd estimate is at around 2.4-2.5 volumes. It's great being able to adjust the amount of foam simply by the tilt of the glass.
