Repitch Oxidized Yeast

[dangove]

So, I recently pulled two Mason jars of yeast to repitch for another brew day coming up

I made two separate starters and repitched the yeast into each

After, I noticed that the yeast (and beer) from one of the Mason jars was definitely oxidized.

If I decant the starter, will the yeast be ok to use?

I would just make sure not to pitch the old oxidized beer into the new

Yeast don't "oxidize". The beer may be oxidized, but a small amount of oxidize beer generally shouldn't be a problem.
In other words, yes, decant and it will be ok.

I harvest yeast to reuse and the beer always goes from light to dark and oxidizes as the yeast waits for me

Have you tried closing the lid?
