I just bottled off the keg for the first time. I used a section of racking cane jammed in the picnic faucet. I turned psi down to about 3. I had a rubber stoppper on the cane as I had read about using this to control the pressure and flow rate going into the bottle. The stopper was not necessary for me. My beer, which was a bit overcarbed in anticipation of loosing some carb during bottling, barely foamed with this set up. In order to get some foam to fill the neck as opposed to just having the bottles completely filled, i would pulse the picnic faucet on and off a few times when the beer reached the neck, and then shut it off and let the beer in the racking cane drip vigorously into the bottle, overflowing it with foam. Then I capped on the foam immediately. I was doing 4 bottles at a time. My bottles were room temperature. I've sampled them a few days after bottling and found that I didn't even need to overcarb the beer. They lost no carbonation whatsoever.
