Yeast Sediment

Is there (enough) live yeast cells in the sediment in the bottom of the
primary fermenter?  If so, could a portion be collected and maybe put in
with some of the leftover wort and stored in the refrigerator for use in
subsequent batches?  Then when ready for them, could they be made into a
yeast starter in preparation for pitching?

In my opinion, you are better off taking your yeast from the secondary - it
will be more free of trub.

Don't add it to left over wort - you'll wind up starting another brew.

Empty out your secondary into a sanitised container,
and put the batch into the fridge.

On your next brew, let your yeast slurry warm up to room temp, and just
pitch it into your wort.

It'll take off in a couple hours. Very impressive !

When you siphon your beer from primary to secondary, you are taking it
off the trub, which is yeast, proteins, hops, and other vital
nutrients to your yeast. While it will be free from the trub, that is
the only benefit. Yeast from the primary contains cells that are still
alive and have significant flavors you desire. There is more yeast and
more active cells in the secodary.

One final point... the original message mentioned leftover wort from
the primary fermenter. That is beer, not wort. Wort is unfermented
beer, and even though beer in a primary for a week or two is not
finished, that is still considered beer.

Re: Yeast Sediment

I reuse yeast all the time. From the primary! After I rack it off to
the secondary I scoop the the nasty stuff off the bottom of the
primary and and put it in a quart jar. Make sure you get some beer to
cover the yeast. Cover with saran wrap tightly, and refrigerate until
I make another batch. All I work with is sanitised. 1 quart can easily
be used to start two 5 gal batches and I reuse yeast up to four times.
I do not however reuse dry pack yeast.
