What's the proper technique for force carbonating? I've tried to carbonate with the recommended volumes of Co2 and the beers flat. Next I crank up the pressure to 20-30psi and shake the keg. Sometimes it will carbonate and sometimes it won't. I always place the kegs in the frig to get them nice and cold first. What am I doing wrong? How long should it take to carbonate? Thanks, Mike
 
Generally speaking, I keep my kegs at about 11-12 psi and 39 degrees. It takes about 10 days to 2 weeks to carbonate them like that.

Sometimes, if I'm in a hurry, I set it for 30 psi for a couple of days and then purge the keg and reset at 12 psi. It's carbed up in 4-5 days like that.

I've heard that some people shake the keg to get it to absorb the co2 faster, but I've also read about a lot of people who have foamy beer that way. It would work, though, if you really wanted the beer carbed up fast.
 
i have the same problem. i have two kegs that have been sitting at 12psi for almost 8 weeks. i only have a few bubbles and they disappear too quickly, and the beer tastes mostly flat. i don't believe i have any leaks.
 
i keep my kegs at 39 degrees and 10-12 psi. When carbing, I just set them at 10-12 psi and give them a quick shake whenever i walk by. it takes maybe a week to carb them, and i haven't had any foaming issues yet.. at least, not like i did when boosting the psi to 30+ trying to carb.
 
Hmmm... perhaps that's why I've always had a problem with serious foam / head... someone I bought my keg equipment told me to run it at 30 psi, rock the keg back and forth on your knee like a baby, until gas stops chumming up into the tank, then come back 1 hr later, repeat and you're set. But like I said, I have some serious foam issues for the first 20 or so pours because of this. I keep my keg at around 35 degrees btw...
 
I set mine in the fridge at 30psi for 2 1/2 days, then re-set to serving pressure. This usually gets me close enough to the carbonation level that I want to drink immedeatly (if I need to :D) but it will even out to where I want in about a week.
 
I carb at 30psi for 2-3 days, then drop the pressure to about 18 for the rest of the week. The beer is drinkable then, but gets better a week or two later. The beer carbonates fairly quickly, but it takes a while for the carbonic acid to build up. I like that "bite".

+1, but I have my system balanced at 8-12 PSI depending on the beer. Make sure you bleed the excess pressure when you drop it to your serving PSI.
 
PSI is dependent on temperature.

For a kolschy ale, you want around 2.4-2.7 Volumes of CO2.

Try this calculator... and be sure to use the pop-up to find your style. Enter it into the calc and click the radio button you want to know the answer to.

+1, good advice! Also I have a carbonation chart in my sig that may be easier to use
