Adding DME To Washed Yeast Before Storing

[riverbeer]

Once you have jarred your washed yeast, is there any reason you can't add
DME and ferment out to increase the yeast count before you put them to sleep?

What's your yeast slurry volume? When I wash yeast I find that I always get so much yeast I've never needed to increase cell count. In fact, I end up filling the jar and pouring the rest down the drain.

The jar can explode if it is sealed and still fermenting. You can make starters, then store it, but that's kind of a bother. You'd still most likely need to make a starter before use, anyway.

IMO, the best way to harvest healthy yeast is to just make a starter that is larger than you need, and save some.

What I would like to do is to store enough yeast in a baby food jar to be able to pull it out of cold storage and acclimate and add to fermenter.

There'll be more than enough yeast to do that from any yeast cake. No need to make more. Get about 300ml or so of washed slurry and you'll be good to go as long as you reuse it within a few weeks.

During the typical ale fermentation the biomass increases to roughly ten times the initial cell count. So from one fermentation you'll have enough for about ten batches of beer. Washing yeast, from my research and experimentation, seems to do more harm than good.

I just store the slurry.

You can expect yeast stored anywhere from a week to 3 months to perform about the same:
