So I was catching up on old NB videos and came across one I had yet to see:
At about 25:30 the Wyeast rep talks about aeration. I found it interesting because he says that yeast need 12-15 ppm of O2, but using an oxygen pump only gets you to 8 ppm after 5 minutes. He recommends 45 seconds of vigorous shaking, because that also gets you to 8 ppm (what we breath). He also says it takes 80 seconds with an oxygen stone.
I was considering getting a stone, but if 45 seconds of shaking (what I've been doing) gets me to the same place as a stone, is it worth it?
Any thoughts from those much more experienced than I?
[Sorry if this has been covered, but my two searches yielded no relevant posts]
