Oxygenation: What does 1 Liter per minute look like?

[Chupa LaHomebrew]

I was listening to the Brewstrong Q&A show and Mylo asked a question about how much O2 to oxygenate beer with and for how long.

Jamil mentioned using an O2 regulator to oxygenate wort at the rate of 1 liter per minute for 1 minute. I'm assuming that's for 5 gallons of wort. But a lot of us use a setup like this, which has no pressure gauge: http://morebeer.com/view_product/16603//Oxygenation_Partial_System_-_No_Filter

So...what does 1 liter per minute look like coming out of a sintered stone? I used my O2 setup for the first time yesterday, and I just tried to dial in the stone to where it was producing a steady stream of bubbles which showed on the surface. I tried not to let the stream become too vigorous or kick off big bubbles. The fermentation looked great when I checked it first thing this morning!

That's what I do. 2 minutes of pure O2 with the surface barely moving. I try to land the stone in the middle of the carboy. Someday I'll make a fancy wand for it, so I can move it around like Doc claims to. I'm just too much of a tard to figure out how to hook up the stone to the wand.

Me too. But they also sell it attached to the wand. This is the one I use and I sanitize it by boiling in the 5L ehlermeyer.

Well, that's easy. Thanks, Bill.

I just cut the top if a dip tube off and use some tubing between the stone and your new wand.
