is FG the best indication of proper wort aeration?

Is attenuation and lag time a better indication of proper aeration as opposed to flavor?

Aren't attenuation and FG two measures of the same thing?
 
But I think the answer is yes, no, maybe - because wort aeration is just part of overall yeast health which includes healthy cells, pitch rate, fermentation temperature, and aeration. Together, yeast health will affect attenuation, lag time, fermentation flavors and off-flavors, head retention, and more. You can't really decouple one outcome and link it to one cause.
 
Also, I'd guess that pitch rate and cell health can hide aeration problems.

Proper areation leads to yeast health which leads to better, faster attenuation, less lag time, and healthier repitch.

I think its not quite as easy as picking one or the other. Like asking if 4 is a good indication that the problem was 2 plus 2. It could have been 1 plus 3, or 2 x 2, or 100 minus 96, but if the goal was 4 and you got 4 I would keep doing what you did.

It would be a pretty easy experiment to set up. Split a batch into two fermenters, pitch the same amount of yeast, aerate one but not the other. Keep notes on fermentation and finished product. Report back to the group.  :)

Lag time is significantly affected by pitch temp and pitch volume, and presumably yeast strain.  I think attenuation and flavor are better indicators than lag time.

For The Win?

And For The Record and For What It's Worth (FTR & FWIW), I'm with Denny and Jim on this one.  Do whatever works.

In the end, flavor is the only thing that matters.  A brewer who makes up all his own rules and doesn't use any of the majority rules of thumb, and can still manage to make excellent tasting beer, to me, is the friggin winner.  It all comes down to flavor.  If differences in process have zero flavor effects, then it is important to note that those differences are not, in fact, important.

Read it in your head with Marv Albert's voice. Makes perfect sense.
