Yeast slurry from 5g. 3 Pints of slurry

So I collected the yeast cake last night. Pretty much took all the beer out when racking to bottling bucket, maybe 10 oz remaining. Poured the remaining cake into 3 pint mason jars, from dishwasher left to cool then sprayed with star san. Couldn't get some of the yeast cake to pour, probably didn't leave enough liquid to agitate the entire cake. Sprayed it with my starsan bottle (lol) to get it moving.

Put in fridge for about 20 hours, the jars are now about 85% full of very thick creamy slurry with like a cm of beer on top. I did not expect this much slurry from the threads/pics/posts on here. What gives?
For what it's worth, I poured the entire pot of wort through my biab bag to filter out the hops. Should just be yeast and break material.

Bump. Anyone have a clarification on this?

it's likely not all yeast. more likely trub with a small layer of a nice creamy color. that cream is your yeast. that's why people wash there yeast. to get rid of the trub, but there are people who pitch the whole works.

Attached pics, I don't see a third creamy white layer in any of them. Only the leftover beer and a homogeneous thick trub/yeast mixture.

not sure. i've only washed yeast once and never got nearly that much yeast. hopefully someone else will chime in.

If you wash yeast you only get a little yeast on the bottom, with beer/liquid in the rest of the jar. When you just dump the slurry, you get mostly slurry, and only a bit of beer/liquid.

What you have in the photos looks like what I got when I did the same thing. I left mine in the fridge for 3-4 days, and it was about 60% trub, 40% liquid by the end.

so how much yeast did you get then?

When I save a whole yeast cake from a 5 gallon batch, I get about two full quart mason jars or even a bit more. Some of it is yeast, most is trub, but you don't see the yeast since it's mixed in with the rest of the trub and not separated out.

It looks fine to me. Use mrmalty.com's yeast pitching calculator, under the "slurry" option to know how much to pitch in the next batch.

I save mine in quart jars, because I do 10 gallon batches from a jar of yeast (and often, that's too much and I don't need a whole quart jar).

that's good to know Yooper because i plan to do the same.

Thanks

Thanks for the input yooper, when doing this what settings do you use for mrmalty?

I should have said 'slurry' instead of yeast. I have no idea how much yeast is in there. I just guestimate and dump about 1/3 of a yeast cake (maybe 1 to 1.5 cups) of slurry into my new wort.

I should also add I've only done this twice and both beers are in the secondary, so I don't really know that much what I'm talking about. They fermented fine at least.

No biggy. Looking at the pics i should have known what you meant!!

Just played with mrmalty for a second, setting batch size to 10g, og to 1.06, concentraction all the way to the left and % trub all the way to the right I get a maximum suggested volume as about 0.6 Quarts...
Do you not trust mrmalty exactly, or am I reading this wrong? Maybe you do a multiplicative factor of the suggested amount?

That seems about right. I let it sit until the next brewday, decant the spent beer right before pitching, and I calculate mine as "thick" slurry.
