I set a warm keg to 40 psi with temp controller at 40F and leave it for 36 hours.  No shaking.  Then set it to serving pressure.  If the beer is already chilled, or if its a style that needs lees carbonation then I do 40psi of 24 hours.

Patience is almost always rewarded in homebrew.

Patience I learned a long time ago;) 3 kids and Homebrewing will do that to you!

You can get faster carbonation if you bubble up through the dip tube.

I gotta tell ya, I tried that a number of times and didn't see any difference.

Thinking about it, question, how? My gas connect will not couple to the liquid post and vice versa or are you switching the valves?

Yep.  I use the flare fittings, which screw on.  It's simple to swap them around.  Another advantage is that if someone shows up with a pinlock keg, I can just screw on the proper fitting.

Well, I think yer crazy! No offense!

And _I_ think you didn't do the experiment carefully!  No offense!

Tell you what. I have a gizmo that reads co2 volumes. This will be an easy test. Let you know soon.

Please do!  I hooked up two kegs, one each way, and hit them with the same pressure for the same time.  But all I had to evaluate them was my own impressions.  This may be the ONE time I was wrong!

 Denny wrong?!?!  Nah, I don't believe it.

Did you shake them or just give them time? Here's the thing, if you have top pressure on the beer and are bubbling Co2 up from the bottom it's going to stay in the liquid more readily as opposed to trying to force it down from the top. But if you do it over, say, a week, it may not make as much difference.

I think I shook them.  It's been so long since I did the in through the out thing that I don't recall, but that's always been my SOP.  These days I just let them sit at about 30 psi at room temp for a few days.  Shaking was too much work!  Believe me, I understand the theory.  It's just that reality didn't bear it out for me.

You "think" you shook them. Boy, doesn't get more scientific than that!

[denny]

I'm pretty sure I did.  Whatever I did, it was the same for both other than the poppet I used to introduce CO2.

The thing is, if you pick up the keg and old it horizontally and shake it, it doesn't make any difference which port the gas is going into.  They're both below the surface of the liquid.

When I did the shaking, I would lay the keg on the floor and roll it back and forth.

So you didn't actually shake it, you rolled it.  You're in the music business, what if you had rattled it? 
Would the gas and liquid ports still be below the surface?
