+1 The IN side might be a good idea. The quick disconects IN and out are different sizes. It could get stuck and be difficult to get off if you put it on the wrong post.

A big factor in determining how fast beer will carbonate is the amount of surface area in contact with the beer. That is why beer will carbonate faster with the CO2 bubbling through it. This is what shaking the keg will do for you. If you want the keg to carbonate faster without doing all that shaking, put the keg on it's side with the gas hooked up. This will pretty much double the surface area.

The other night I carbed a keg of beer at room temperature while sitting at the computer. I cranked the CO2 pressure up to about 30 PSI ( I checked the temperature/pressure chart for the correct pressure) and hooked it up to the keg. I put the keg on the floor under the desk and rocked it with my foot ever couple minutes. With my bare foot I could feel the vibration of the gas going into the keg. When I no longer felt the gas going in after rocking the keg I knew it was fully carbonated. I stuck it in the kegerator to cool down before hooking gas up at serving pressure. Sure enough the carbonation was perfect.

I am new to kegging and didn't know that the two posts were different sizes, they looked the same. Since this is a dark strong Belgian, and needs to age anyways, a week on gas won't be much extra. I do like some of the other ideas for faster carbonation on some of my other brews. The whole task has been to move away from bottle conditioning and carbonation control. It still takes time. I'll say this, even undercarbed, the beer was damn good :aaron

Not only the posts different sizes, they are even different from keg to keg depending on the model. This will give you an idea of the sizes.

It won't carb any faster going in the out or out the in unless you are shaking it. It takes a week or there abouts either way.


+1... it takes about a half of a second for a 3/8" bubble to rise up through the beer before it becomes one with the headspace. I seriously doubt there is that much additional absorbsion happening during that trip. All of the rest of the carbonation will come from the surface area in contact with the headspace. I suppose you could carb it up with the keg on its side for a little additional headspace (provided that you don't overfill your kegs (like I do... :D ) - but again - I doubt there is much difference if you are not going to shake it.
