Is aeration while sparging OK or will it have detrimental effects ? (Hot wort aeration)
What about just prior to pitching the yeast ? I assume that is OK, but is it possible to contaminate the wort with bacteria or mold doing this and if so, how does one prevent it ?
What about after pitching the yeast ? For how long is it OK to aerate ?
While not aeration, is it ever advantageous to stir a fermenting brew ?
How bad is aeration when racking ? Is a little air OK or should the goal be absolutely none ? I've noticed that otherwise stable beers will start fermenting after racking. Is that due to aeration and is that a good or bad thing ?
Generally I am paranoid about aeration and oxidation. I am wondering if am over doing it.
Thanks.
