After 10 days in my keg, pressurized at 10lbs, my beer comes out with a nice head, nice lacing, but still tastes like it is flat. What's up with that? Do I need more pressure? Or does it just need more time to carbonate properly?

What temperature is the beer at?

[weithman5]

salt
seriously, i do this on occasion.

What temperature is the beer at?

+1

Is the system balanced?  Check the attached chart.  Determine which volumes (vv.) of co2 you want, what temperature you want, then set the psi accordingly.  If you have done this, then it is just time, OR you are telling yourself you want more vv. co2.

or you got beer gas instead of straight co2

it is at 37 degrees. 5 feet of 3/16 inside diameter line, faucet is 2 feet above the keg.

Try dropping you pressure to 5-6lbs and then pour.  How is the carbonation?

As I said in the original post, it pours with a nice head, has nice lacing, but tastes flat.

Got a pH tester?

I'm still learning this stuff, but it does sound rather like beergas or something similar.  pH should tell you if you've got sufficient carbonic in there, though you'll have to dig or test commercial examples to get a comparison. Water profile being weird for the style seems plausible, but I expect you'd notice it every time you brew the style.

My bottled beer carbs just fine.

I can carbonate a beer in about a day with enough chill and CO2 pressure, but it won't be right.  I feel that it has something to do with the 'hydration' of the CO2.  You can get the CO2 into solution, but it then has to hydrate.  That hydration is a slow process.  In my experience, about 2 weeks is needed for the carbonation to become 'normal'.  That beer should be getting close.

Thankyou! Maybe I shouldnt have turned the pressure up 2 more pounds.

[topher.bartos]

Yeah, carbonating in a keg takes awhile to get it into solution depending on the amount of pressure and temperature and other stuff...

Maybe put it back under pressure for a few more days if you're not okay with it.
