Great question!
I would say that I get an even bubbly flow, not so that the surface is churning,
and I do move my wand in a circular motion while oxygenating. I would call it a medium flow. Maybe I should get some type of flow gauge so that I can measure the rate of flow. Does such a gauge exist? hummmmm......

After doing this, I removed the same volume that I tested earlier and then measured the ppm. I recorded a reading of 4.6ppm of O2. Not too good for all that shaking.
Bottom line? I'm going back to injecting pure O2 for 45 seconds and save myself some work. All that shaking for practically nothing.
Hope this helps!

Going from 1.5 to 4.6 is a pretty nice increase considering you increase oxygen by 300% without any investment other than an upper body without. Yes it pales in comparison vs pure O2 but your yeasties will appreciate a 300% increase.
Also thanks for posting data. Actual measurements are always welcome.

I have since corrected the op. The sample that was tested before the shaking today came in at 2.3 ppm. Sorry for omitting that piece of info.  |

This is a really cool thread to follow. What is the orifice size of the stone your using?

What are you using to measure and where did you get it? I thought the equipment to check it was like $1000¿

Think you could post up a video next time you aerate some wort? I have an 02 setup, but often wondered how much to goose it. The last couple batches I've done i just set it at a mediumish rate and swirl the wand like you, for about a minute. Sounds like I'm close. |

I'm using a 2 micron stone affixed to an acrylic racking cane. The next time I oxygenate a wort, I'll provide some pics. |
