Harvesting yeast from blow off?

[241]

On my most recent pale ale, which was very clean and mostly trub free going into the fermenter, I had a very active fermentation which blew off lots of yeast into my star san jug.

In looking at the bottom of the jug I'm seeing clean, white yeast. About an inch of it in a 1 gal container under the star san. I'm wondering, is it possible to decant and harvest the yeast out of star san?

Any reason not to?

I wouldn't think so. As long as the blow off hose was sanitized. Whip up a starter or a 1 gallon batch with the yeast and test it out. I would think it's fine.

Thanks. Will give it a try

Burton Union system worked that way. The blow off was piped to fresh wort.

Interesting concept.

So I have a starter whirring with this yeast in it. I decanted all of the star san, poured some wort in, swirled it around and poured it into a flask. It's right at about high krausen. Will be separating it out to use in separate batches, but looks to be 100% normal.

Will update once I've fermented with it.

For reference it is WLP002

I do it all the time - sanitize everything and it's $ in the bank...
