Seems to be getting a little better........I guess it's that patience thing again..... ;D

How long has it been kegged?  The longer you give the CO2 to go into solution in the beer, the better the foam will be.

I think the rock and roll procedure gets a bad rap because people think that their beer will be perfect in just 5 or 10 minutes and that's just not the case. Yes, it helps speed up the process, but you still need some time to allow things to settle and stabilize, if that word can be used for beer.

Keith, I too shake kegs to force carb and haven't noticed that having a negative effect on foam.  But that doesn't mean I don't believe there are foam positive proteins that can get used up.  I take it to mean that I have enough of them that I can Use some up and still have plenty.

This is something I think is in need of discussion of itself I think. Like I mentioned before above: have you ever shaken a beer with a carbonater cap on under pressure? You get no foam. I assume that the foaming under pressure i very minimal under pressure in a corny keg as well. If the foam is not being formed under pressure, are the "foam positive proteins" still getting used up?

In addition to what else has been said, letting the beer cold condition can help improve foam stability. Also, as was mentioned, the "quick carbing" process works better after a couple days of sitting to allow the co2 to absorb into solution.

That's a very interesting thought that hadn't occurred to me.  You may be on to something!

Also, per the weyerman presentation in the pH forum that Ron just posted, high pH in finished beer seems to have a negative effect on foam (per that document, I have not tested that but think I might in the future).

Yup. Kegged on Friday......perfect now. Nice head, retention and lacing. I'm a happy brewer. Now for the REALLY bad news...
I added a regulator and bottle pressure gauge for kegs 3 and 4 and when I moved the keg it was very light........... ::) :o

OH NO...... my beer has gone light.......

Thursday I'm brewing another APA and a Belgian IPA.

Seriously thinking about 50lb bags and 10g batches here......
