Yeast Washing Issues

Postby Malt_Man_John » Mon Jun 26, 2017 8:06 am

I tried yeast washing for the first time last week. Let the yeast, trub and water settle out in a large jar in fridge. Next day decanted into sanitized jars, leaving trub behind. When I went to make a starter I assumed whatever had settle out in the new jars was more trub, so I used only the top portion, leaving the settled out part behind. Now I'm questioning that decision. Since yeast doesn't stay in suspension indefinitely, perhaps what I left behind was not so much remaining trub, but perfectly good yeast that had simply flocculated out. The starter itself was active immediately, is still bubbling two days later, but the yeast looks looser and grainier than I'm used to seeing. IOW, I'm wondering if by decanting only the top portion into the starter flask, I may have ended up with the less flocculant spectrum of the yeast. Perhaps I should have used the bottom portion as well, instead of assuming it was trub.

What do you think?

It's possible. I gave up yeast washing years ago because I found it to be a PITA with no payback. My beers didn't get better by rinsing yeast, and I decided it was just one more thing I could potentially screw up.

It's pretty easy to just save the slurry in sanitized containers. That way I don't have to make a starter like I would for fresh yeast.

Problem is the brew shops around here are phasing out WYeast. Takes up too much room I guess. Maybe they should revise their packaging. WL did, by switching to small pouches from the vials.

I just discovered what the problem was. Too little yeast for the 1 liter starter. It's hard to know how much yeast there is in those jars. Now that it's been a little more than 48 hours it's looking better. Probably be able to use it tomorrow.
