Do people aerate with dry yeast? In theory you don't need to, but regardless of how the beer turns out it could change the lag time.
I don’t understand - why would aeration NOT be necessary with a dry yeast over a liquid yeast? I aerate my wort regardless of the type of yeast I use. Is it not necessary to aerate with dry yeast?
Because when dry yeast is produced, it's growth is stopped during sterols production, so it's loaded with sterols. The purpose of aeration is to allow the yeast to produce sterols. If they're already there, there's no need for aeration.
