I used US-05 in my last batch and pitched into what I thought was a trifle high due to the ambient temp reading the range of pitching temperature put my mind at ease. I still do aerate my wort, maybe I should do a test which petru suggests aerate one batch and not another.Here is the latest US-05 spec sheet.
It doesn't mention wort aeration at all, I'm far from sure whether that means that they expect that
1/ any sensible brewer will have aerated their wort as a matter of course.
2/ It isn't necessary
They still recommend 50-80g/hl, at 23l, 50g/hl is 11.5g. No information is given on the effect of wort gravity so its pretty fair to assume that they are talking about "standard beer" (12oP and 25IBU (1.048)).
I suspect that if you aren't aerating you would want a bigger pitch rate to compensate, say up near the 80g/hl (~18.4g/23l). Good idea to pay very close attention to the recommended pitching temperatures to.
This is where I read about Fermentis suggesting not to aerate the wort.
