Found them listed at Lowes.

Do you have a simple "rule of thumb" volume to put in a cornie keg? I read your thread, didn't understand much, but I read it. Should I use half a cylinder, more, less...?

Way, way, way less than half a cylinder.

For a five gallon batch, you need about a quarter of a gram of oxygen dissolved. I fill up my corny to about 19 liters and then fill the headspace to 3-4 psi. It's hard to track exactly how much of a cylinder that is, but we're talking dozens of batches per can.

Ok so I doubt I'll want to use 1/2 a bottle of O2 per batch. I think I'll just seal up the fermentor and run O2 through a stone for a minute or so. This should raise the internal pressure a bit which should work well. I usually wait a few days to "close" up the fermentor but it seems that those who have used the closed O2 process seal it up from the very beginning. Anyone see any adverse effects on fermentation because of this?

Ok...sounds like a simple process then.


I will be using a second cornie for blow-off, so it may take a little extra, but I'm still figuring it to be a nominal amount.

Will be instituting this into my process with my next round of brews between semesters.

If you're using a 5 gallon corny for blow-off, you'll require vastly more oxygen.

When counter-pressure filling several kegs, how do you know the keg is full and beer is at safety distance form gas dip tube?
(My batches are 10 gal so I should use 3 corny's for fermentation and transfer them into 2 serving kegs)

if teh source keg is cold you'll see condensation form on the receiving kegs. if you setup an octopus to fill multiples, you'll get even amounts in each at the same time.

Nice setup, but I am thinking on keg2keg transfer... although it would be nice have sankey keg for this.
I'm not sure how well will condensation show level at normal flow rate, especially in winter.

I ferment in 2 and transfer to 2.

Your way, maybe by weight.

If you don't need razor precision, You could always use an analog bathroom scale.
