As BIAB brewers we often hear about how BIAB should suffer from massive HSA staling effects...
Of course, the empirical evidence that we have gathered is that HSA seems to be a myth.
I've just finished listening to a BrewStrong podcast on HSA, where Charlie Bamforth, Professor of Beer at UC Davis, basically comprehensively dispells all the myths of HSA, and leaves John Palmer virtually speechless...
Brief Summary,
HSA, if anything, is an irrelevant effect, the yeast treats it as oxygen, will clean it up and turn it into alcohol, and it is far far far more important to be careful of Cold Side Aeration and post-packaging storage conditions.
So, yes, avoid splashing your hot wort around, but don't worry about it...
but DO worry about splashing your fermented wort around!
And, yes, you should store your beer in a fridge.
"In the episode of Brew Strong, Jamil and John welcome head of the Brewing Science program at UC Davis, Dr. Charles Bamforth to the show to help explain and cover hot side aeration. Dr Bamforth explains some of the myths and legends surrounding the controversial topic and instructs brewers on how to deal with HSA based on his own extensive research. This show should not be missed by homebrewers and professionals alike!"
