keg carbonation

[enderjones]

I am pretty new to brewing, but had a question. Has anyone tried to carbonate the keg using the out port of the keg to allow the gas to go up through the beer? Does this help speed up the carbonation process?

Some do it that way, doesn't seem to help much more than minimal due to bubble size.

If using a 0.5 micron carbonation 'stone' that's actually held low in the keg/beer by a length of rigid John Guest 3/8 tubing, yes, it can speed up carbonation. Otherwise, simply forcing CO2 down the liquid-out dip tube won't make much difference. Surface area being one of the factors influencing the rate of carbonation. Even better, exploit the billions of active yeast cells suspended in the green beer by naturally carbonating in the keg, ideally with a spunding valve.
