Good broadcast. It backs up info I just came across recently at:
http://blog.flaminio.net/blogs/index.php/beer/oxygen/081408-wort-aeration
This guy Mike has done a number of experiments on wort oxygenation with a dissolved O2 meter, and has come to the conclusion that the best way to achieve consistent oxygenation of 12 ppm is to give the fermenter's headspace a 1-2 second shot of 5 PSI oxygen, and stir for 30 seconds using a paint stirrer.
This not only looks to be a super efficient usage of oxygen, but also very fast. He also claims that using an oxygen stone yields very inconsistent results for the amount of dissolved oxygen. All in all a very interesting read.
The Brewstrong guys also mention that the whole point is to put O2 in the headspace and mix thoroughly, and the blog provides the numbers of exactly how much O2, and how long to mix to get 12 ppm. Nice. :rockin:
