I just ordered the Williams Brewing O2 system. (2 micron stone)
The person I spoke to said the suggested rate is 20 seconds at a moderately high rate.
In Jamil Zainashefs book (Yeast) he mentions 60 seconds, but I don't think he specifies a flow rate.
The regulator doesn't have a gauge, but supposedly you can open/close the valve to regulate flow.
1. How long (in seconds) do you Oxygenate the wort?
2. What flow rate do you use?
3. After aerating, some (a lot) of the O2 bubbles break the surface and are released into the atmosphere. Do you use a lower flow rate, and then seal up the fermentor and shake it for 45 seconds, trying to dissolve the O2 in the head space back into the wort?
4. Anything to look out for? Mistakes to avoid?
