Hello, picture below is a 32oz jar which contains the results of washed 1388 yeast: one image is a side angle, the other is of the bottom.

Question....then backstory, in case of curiosity / interest:

Question....Is it possible that all of this light shade solid matter is yeast, or is this a combination of useless lees matter with some yeast sprinkled in? The bottom angle demonstrates that some darker matter is on the bottom of the jar, albeit a small amount.


Backstory …. 5 gallon BOMM made with four pouches of 1388 (I used four because I forgot to make a starter with one pouch, so I simply purchased four 1388 pouches). Once FG was 1.000, 5 gallon bucket was cold-crashed in temp controlled freezer (liquid temp 33F). After one week cold-crash, racked off to new vessel, then collected the bottom solids to harvest yeast for washing and reuse.

I followed the protocol with boiled (then cooled) water into 5 gallon jug on it's side, let sit, then separate liquid from solids into jars....wash rinse repeat. After seven days in fridge....this is the only jar that has separation. All the other jars are shaded water. I didn't discard anything, rather opted to simply use more water and jars to minimize mistakes. The background jar in first photo is one of those 'water not discarded jars'.....but that jar has no separation of any kind, not even a thin layer on bottom. I've got several of those and they all look the same....no separation in those 'water not discarded jars'.

So maybe all this is yeast, or is it all lees and I got it all wrong? Thoughts? I've been looking at this jar under different light, angles.....trying to detect two layers within the solid matter. It just all looks the same except for the extreme bottom which does illustrate darker shaded matter.

You cannot wash yeast and you cannot remove dead yeast or separate it from the living in any way at home.

What you can do is strip the yeast off it's natural barrier against competitors or aggressors which is either the beer or the mead it lives in. Which you did.

Don't do that again. You can replace the liquid with beer, that should keep it alive for longer.
