Putting this out there as I am not able to find any definite direction so far. I have evolved my brewing technique from making lots of splashing into my fermenter as I cooled my wort to collecting all cooled wort in the fermenter then inserting an air stone with pure O2 for a minute to make happier yeast. now I am looking at an inline setup as my wort passes from the chiller to the fermenter but I am thinking that using pure O2 would over oxygenate and a fish pump with a heppa filter would be best with a flow meter regulating anywhere from half to 1 litre per minute of air. Can anyone offer their experiences please and thank you.
