I’ve been using pure O2 “injection” for a while as my method of aerating/oxygenating my wort prior to pitching yeast, and I wanted to check to see how everyone else does it, to make sure my methods are optimal. I appreciate any feedback:
I use a 2 micron stone (it’s permanently attached to a wand) and will turn the simple regulator on just enough to push air through it, and swirl the stone in the carboy for about 60 seconds.
Should I be using a higher flow rate? Should I be opening up the regulator as high as it goes? Is 60 seconds an acceptable amount of time for low-flow through a 2 micron stone? Is there anything else I should consider?
