Another reusing dry yeast question.....

Post by gobuchul » Wed Apr 15, 2020 10:38 am

So, I have a little lockdown production line running.

Planning the next few batches, it will be easy to be kegging a batch on the same day as brewing another.

After kegging, can I simply take a couple of hundred ML of the yeast cake and remaining wort and pitch it into the next batch?

Will that work?

I've done it that way with a lager yeast, it definitely works.

The only thing to watch is that dry yeast don't really need aerating, whereas if you're pitching "wet" yeast (regardless of where it came from originally) then you'll need to aerate it to allow it to build up the sterols it needs to multiply.

Done much the same this week and it's fermenting happily :)

There are a few things to look out for :-

Reusing yeast from a very hoppy brew might not go well.
Obviously contamination.
You need to oxygenate / airate the wort I do it with all yeasts.

Well that went like a rocket!

Yeast from a London Pride clone onto a hoppy single malt ale and over night the krausen is very thick, wavy and high.

I'll be doing it again in the next couple of weeks.

Excellent. Instant protection for the wort from any airborne or otherwise introduced nasties. Should finish it's fermentation very quickly as well.
