Closed up the fermentor shortly after 11PM las night. This morning I saw the air pump on my counter and realized the wort didn’t get the 60-second aeration recommended by BrewCipher. Yeast activity has commenced in the bucket. I don’t have pure oxygen, but do have an inline filter for the pump. The stone has been sanitized, as has the tubing downstream from the filter. Would you pop the lid and aerate or just let it ride? Thanks in advance.
Yeah, let it ride. Anecdotal, but I never ever do any more aeration than letting the wort pour into the fermenter from ~3ft up via my Robobrew's ball-lock spigot. Even on a 1.121 stout I did. Never had a stuck fermentation.
+# whatever. The point of aeration is to help the yeast in its growth phase. If it's already fermenting it's not going to stop to grow so the oxygen is probably harmful (although it should just get scrubbed out). As an aside, if you pitch enough yeast it won't need to grow and should start fermenting almost immediately. Most believe that over-pitching is a bad thing because it can lead to diacetyl but I have never seen that happen in 24 years of professional brewing.
I agree with this. But I'll add that to pitch enough yeast so that there's virtually no growth, you'd have pitch a whole lot of yeast. Like pitching on a whole yeast cake at least.
Yes, for a home brewer it would be hard to do, which in my opinion makes the fear of over-pitching and getting diacetyl even that much more of a fallacy. It's almost impossible to do.
Jeezus, @riptorn jinxed me. I brewed a Bo Pils today, 1.059 OG. F*cking O2 regulator failed. Oh well. Splash O2 lager it is.
