Default Force Carbing - Upside down?

If I go to force carb, but turn the keg upside down when I pressurize the keg to 30 psi, won't the gas be forced to bubble up through the beer to get to the headspace?

Won't that help speed up the process?

I was thinking that myself actually... curious of the answer. From what I've read, if you can turn it on it's side, it will have more surface are/CO2 contact which would be even better. Of course, unless you have a fill size fridge to do this in (carbs better under cooling) it's hard to have a keg on it's side under pressure while being chilled.

If you are willing to try that, you might as well connect the CO2 to the liquid disconnect and carbonate that way. Either way risks getting beer in your co2 line, but turning it upside down almost assuredly will.

As far as being a speedier process? Let us know.

Wouldn't 30 PSI of CO2 keep the beer out of the line?

I was thinking of hitting it with CO2 outside the fridge, upside down, then unhooking it, shake, repeat.

Until the pp of CO2 hits equilibrium and then you just have an open system - the beer will most assuredly pour back down the line.
If you threaded fittings on your disconnects its easier just to put the CO2 on the beer line and bubble it up from the bottom.

You will get far better levels of carbonation by laying the keg on its side than you ever will by bubbling the CO2 through the beer. And I certainly wouldn't want to risk the chance of beer making its way into my regulator!

Until it hits equilibrium there will be more pp coming from the tank side- keeping the beer out of the line.

After they equal out, the beer will be able to flow back.

It will help, slightly. The bubbles will be large & won't provide much extra surface area. You can buy diffuser stones for kegs that produce very small bubbles, but you need one for each keg.

Shaking helps much more. If you can't shake a full keg, you can lay it across a piece of closet rod and rock it.

I was shaking my keg last night to help it carb and I got beer in my gas line. Is that a big problem? Do I need to do anything about it?

It's a problem if it gets into your regulator. You may need to tear it apart and clean it out. Do you have a check valve?

Not directing this at you Coastarine- If you go through the trouble of brewing and properly aging a beer, what's one more week going to hurt? Please people, quit shaking, rolling and otherwise molesting your cornies. It's not worth it.
