If this has already been addressed elsewhere, I apologize. I'm curious if yeast choice makes a difference when brewing low O2? Especially, can a Kölsch be made using 029 fermented at 62F and turned around a little quicker than a cool fermented lager?

Seems to me the process is yeast and style independent, just want to make sure. Thanks!

If you are asking can a kolsch be made with kolsch yeast,sure.  If you are asking if you can use kolsch yeast to make a tradional lager say a helles... then sure. But it won't be a helles,  it would be a kolsch. The esters from the yeast make it not like tradional Bavarian lager strains.. along with that you won't get the sulfur and the yeast derived sulfites to help protect and achieve the proper flavor profiles.
Low oxygen brewing is an overarching technique, it's not yeast and style dependent.

Thanks, it's for a Kölsch.

I'm considering this.  Think it would work with a siphon instead of a dip tube and bulkhead?

The first glance made think it was an air filter from a carbureted car back when. Maybe a vendor had excess tooling to make these?

I had the same thought!

If one uses an immersion chiller, wouldn't it get in the way of that?

Whirlpool should be performed after chilling and removal of the immersion chiller.

I don't understand how it works. Whirlpools push the break out to the sides where gravity pulls them down and to the center. If that things gasket is on the bottom, how is break getting in the middle?

I suppose I can see it working, if I squint really hard...

Thanks for sharing all this great information. Most, if not all of it, just makes sense to me and I'm going to incorporate it slowly into my system. So far, I've tried spunding on an AIPA and I've had encouraging results. However, my wife gets bad headaches from sulfites in wine and, since stopping the use of SMB in my homemade wines, her wine-related headaches have ceased. She enjoys my beer as well and so I'd prefer to not add sulfates to it. Are you aware of any possible substitute to SMB in the mash for scavenging oxygen?

For sure!
Well you are in luck cause we get to boil beer, which does help get rid of some of those sulfites. I would recommend you cut you SMB dosage with Ascorbic acid 50/50 and give it a whirl!

I'll try that. Worse case scenario, more beer for me! At least short term anyway. Any all natural solutions? Would using the antioxidant properties of say, hops in the mash have any potential benefits?

Mash hopping is certainly a thing. So is first wort hopping. Both likely have some antioxidant power.

Another option, especially if you are an ale brewer, is to try ascorbic on its own or cut ascorbic with a bare minimum of SMB.

Right. And perhaps lodo could give some legitimacy to mash hopping!

All those things are all natural

Mash hopping is a thing, but it's not the magic bullet. You can always purge everything with nitrogen, and mash under a nitrogen blanket.

SMB/AA it is,then! Although I fully expect further innovation as this LODO thing gains traction! Thanks again!

I spent a year working with ascorbic acid and found that it did nothing for me.

Did you use a DO-meter?

Hops contain antioxidants. So does malt naturally as well.

Not preboiling/deoxygenating the water before you use it in the mash (like your SMB trials from long ago) use up all the antioxidant properties immediately trying to get rid of the oxygen in the water. So you will see absolutely zero benefit from it.
