that's the risk with over pressure plus agitation for burst carbing. A safer way of burst carbing is to put 30 psi on a cold keg for 36 hrs (no more), and no agitation. Then vent the headspace, and set to serving pressure.

That works, as long as you have more beer[emoji1]
I just lean the keg over ~45° and back repeatedly. No need to get overly aggressive about it

You can put a gas QD on a liquid post, but they are a little loose, and don't seal well. You could potentially lose a lot of CO2 in a hurry doing this. If you want to carbonate thru the liquid post, put a liquid QD on the CO2 line.
thank you ! DougYou can put a gas QD on a liquid post, but they are a little loose, and don't seal well. You could potentially lose a lot of CO2 in a hurry doing this. If you want to carbonate thru the liquid post, put a liquid QD on the CO2 line.
The other risk of feeding CO2 into the liquid post is: beer blow back into your regulator. You have to have check valves, and trust them completely, if you are going to do this.
Bubbling the CO2 thru the beer (by feeding gas into the liquid post) should carbonate a little faster, but I haven't seen any hard data on this. If time is an issue that using the 30 psi for 36 hrs, then drop to chart pressure works in about 3 days. It's what I do.

You get big bubbles without the stone, so the effectiveness is greatly reduced. Proper use of a stone starts at low pressure, then gradually raising the pressure as the flow slows down. Some experimentation is required to determine the proper CO2 flow rate such that the CO2 bubbles dissolve before they reach the surface. If the bubbles break the surface, then that CO2 just adds to the headspace pressure, and only slowly absorbs into the beer.
Assuming you don't have foaming problems with beers that have been on tap for a while, you probably just need to chill for 2-3 days in order for the CO2 in the headspace to dissolve into the beer, and to make sure the beer has actually gotten down to 37°F.
My calculations put 38 psi @ 74°F equal to 13.25 psi @ 37°F (2.75 volumes.) 10 psi @ 37°F gives 2.43 volumes.

This part of your process seems unnecessary and is probably counter productive. At this point agitating the keg creates cavitation which provides the CO2 an easy way to come out of solution. You can test this with a simple experiment. Next time you have a can or bottle of beer, vigorously shake it prior to opening. Just like that can or bottle it'll take time for the settle back to equilibrium.
Interesting! Just a Chugger pump, huh?
Beer troll giving big thank you to thread starter,bobby is the one who helped me with this.Yes it is a pump.Inline carb steps. I do like it as i can use my gear instead of buying more for this..There are steps to do this ,you can see my pumps all have priming valves ...The main step to get the hoses primed ,stone turn on,then purge the keg..I will purge a few times in the begining...Before i even do any of this i will do the same thing with pbw ,but without the stone ,rinse,then starsan...it is keg washing ,,kegerator line cleaningWell. I hope that you CAN help! I'm about to brew a Bass clone and thought it would be a nice touch for the holidays to infuse it with "helium". Now I've combed thru you tube for forced carbonation methods using helium but the only vids. that I find is folks sampling one. My thoughts were to bottle half of it in bottles and the other half keg it in one of my 2 1/2 gallon kegs. I believe the keg would work best under forced carbonation in leu of Co2 I would use Helium! Being that this is a different gas I realize it will have a different saturation rate and requires unique pressures. Any help here would be appreciated gang! I hope to begin brewing very soon!
Actually, Helium is ~1900 times less soluble than CO2 at 0°C (32°F), ~1500 times less soluble at 10°C (50°F), and ~1100 times less soluble at 20°C (68°F), but the fact that you can't dissolve much He in water (or beer) is indisputable.
Bobby would be able to explain it better than me.
Great! Im aware that its a gimmicy thing to do but several breweries have tried it and it also wish to try it. Without engaging into deep debate on the subject I gather from what you have said that attempting to carbonate at similar pressures and temps as co2 would not work due to less solubility? perhaps you might suggest something that may work?Actually, Helium is ~1900 times less soluble than CO2 at 0°C (32°F), ~1500 times less soluble at 10°C (50°F), and ~1100 times less soluble at 20°C (68°F), but the fact that you can't dissolve much He in water (or beer) is indisputable.
Also a "volume" of CO2 is a bit less than 2 g/L (2 g/kg, 1.977 g/L for the truly nerdy), so a beer with 2.5 volumes of carbonation has just under 5 g/L of CO2.

OK,I was the one that began this thread and Im interested in a hands on reply. With all this talk of how insoluble helium is vs. carbon dioxide it sounds as if a mix of the two gasses is needed to achieve the desired result. I have spoken to a few pro brewers currently making a living at brewing beer. and when they actually approach the idea with an open mind some have suggested to carb. w/ Co2 and dispense with helium. Yet this idea I believe would result in the helium evaporating as soon as its exposed to open air. This gives way to carbonating with Co2 and then "adding" the helium on top of that at the lowest temp. possible. Or feeding both gasses into a splitter and leave it all in the fridge for a day or two. Its my thought that the two gasses would be absorbed at their own rate and be closer to achieving the desired effect.
