Wort Oxygenation

[Chris Banks]

What methods are you guys using for getting a bit of o2 into your chilled wort?
Im over trying to shake ~23l of wort around in vain!

[JoKing]

I shake it... works for me!

[Reviled]

Same, just shake the shit out of the fermenter with the wort in it, either prior to pitching, or after ive dumped onto a cake, never had any problems with aeration...

[James P]

I tried pushing O2 in from a scuba tank.... ended up with wort all over the place. I now shake.

[denimglen]

Shaker here too.

I've done a few lagers and a couple highish gravity beers and never had any dramas, I reckon as long as your pitching rate is good you're aeration doesn't need to be perfect.

I just siphon from kettle to fermenter, the drop is far enough for it to aerate nicely, there's a few around that do it

[Pilgrim]

Drop from the brew kettle into the fermenter and stirring like a whirling dirvish with a slotted stainless steel spoon gets a good head on it :-)

Cheers Fullas looks like im doing what most of us are doing so maybe i will stick with it!
Shake it baby shake it!

Basic Brewing Radio (excellent podcast, and not just "basic" either) covered this a while back with some very in depth research. The result is here, but the summary was that shaking is actually *better* than an oxygen stone in comparitive amounts of time, up to (I think, too lazy to read it again) about half an hour of oxygenation. Anyway, read for yourself and decide. :) The podcast episode itself is here.

[Chris Banks]

Cheers for that Greig some very interesting info there!

[JR]

Definately a different podcast experience from the Jamil show - good though and well worth a listen.

I don't think that it was that study but I recall reading something a while ago that claimed that shaking your fermenter was MORE efficient than using pure oxygen through a stone. I don't know if I dreamt, it but I think it also claimed that shaking with ambient air was MORE effective than shaking with pure oxygen... don't make no sense! I cant remember where I read it but it was somewhere I trusted, might have been from white Labs maybe...

Yep, just had a read through that PDF again, and that was indeed the conclusion. The graph at the end says it all. I think there are a couple of flaws in the testing methodology, but it's good enough for me. Still, not that easy to shake a 2000L batch I guess! ;)
