Reusing and storing yeast ??

[Sdtastentune]

I want to start reusing yeast. I have 5 gallons with wlp001 in it, started from a liter starter about a week ago. Looking to transfer that to a secondary and harvest the yest for two upcoming ipa's in the next week or so. Should I just scoop it up into two separate jars and into the fridge, and pitch normally? Add water? Thanks!

If you are going to store it for more than a day or two, then read up on yeast washing: Washing yeast - Home Brewing Wiki

If you are going to use it right away, then you can dump it right into the next batch.

If you store it or it has been sitting as a cake for a while after primary the yeast will go dormant. Make a starter again with it the day before pitching.

mrmalty.com has a calculation for pitching slurry amounts.

IMO keeping it in the fridge will be OK as long as everything touching the yeast cake is sanitary. I have made starters from yeast cake almost 2 months in mason jars from the fridge.
