Aerating Starter?

[IgorRVA]

Recently got myself a little O2 system, other than aerating your wort, how about aerating my starter yeast? I would think it only makes sense, but any thoughts are appreciated. Thanks

Simple shaking of the starter is enough ever so often if you don't have a stir plate. If you do have a plate then the aeration is done for you while the yeast do their thing.

Aerating with an aquarium pump would work better. To much pure O2 can be detrimental to the yeast.

I think a stirplate for $50 is a bargain when it comes to propagating yeast. I just turned 2 vials in a 1G starter into a huge amount of slurry, can't wait to pitch them into my DIPA.

A reasonable O2 injection in a starter, if you aren't stirring, is a good option, though. I personally do starter / stirplate, then O2 injection pitched into proper temp wort. I get wonderful fermentations.
