Yeast recycle, how many yeast to use

[chavatj]

I have a question, i collected all the yeast from my previous batch, how many of that yeast do i have to use for my next batch?

Check Mr. Malty's online pitching rate calculator. It'll tell you how much slurry to use.

Best bet is to make a starter from your slurry if it's more than a couple days old. Mr. Malty will tell you how big of a starter to make.

Around 180,000,000,000 for a 5.25 gallon and 50 GU :cross:
