Will Carbonation Level Drop if left at Serving Pressure?

[Sippin37]

I normally carb my beers up at 11-13 PSI in my kegerator. Then I turn my serving pressure down to 6-7 PSI when serving to reduce the amount of foam (only really do this when people are coming over and consuming consistently from the kegs, not when I grab a pint or two on a weeknight).

So my question is if the beer is carbed to 12 PSI and then I leave it at 6 PSI for a week or so, will the beer slowly go down to 6 PSI as well?

Thanks

Yes it will.

This is what I use to do. The carb level will drop slowly. But just make your serving line longer. Problem solved.

Personally, I have found it takes a very long time for me to notice a drop in carbonation when I do what you are describing. Whether that means I'm just not detecting the difference, or it really does take a long time (I mean 2-3 weeks), I'm not sure...

It's a slippery slope to even acknowledge the term "serving pressure", never mind practice same. No good will come of it...

Cheers!

I'm with the "Buy longer lines...problem solved" group where you set the pressure based on temp and volume levels and leave it alone. I have 10ft lines and pour perfect pints each time.

Thanks for all the replies. I think I will eventually get some longer lines. It's not that annoying currently but it is on my list to do.

It has virtually nothing to do with time, but rather how many times you pour a beer. If you never pour a beer, the carbonation won't drop at all. Each time you pour a beer the headspace pressure drops, allowing a little CO2 to come out of solution until it reaches equilibrium again. Do this enough times, and the carbonation eventually drops enough to match the lower serving pressure.

If your not careful or have check valves you can back beer up in your gas line or regulator
