You need to calculate the total number of cells needed which corresponds to a volume of slurry at a given thickness and viability. There is a bit of estimation involved but mrmalty.com will help guide you on this.

OK, so here is what I have. I saved all the slurry from the Becks in a container. From there I washed it several times until there was a clear separation of water, yeast and trub. Now I just decanted the water, yeast and a little trub in a separate container. The plan was to see how much yeast I have and make a starter from there. If I saved all of it from my last batch and it's at 60% viability, I figure I'm either right where I need to be or should make a small starter.

Should I now just estimate how much yeast I have, figuring the yeast concentration is on the high side and the non-yeast percentage is on the low side? Seems right but please chime in if I'm missing something. I want to learn how to calculate this properly. Thanks.

Ron, hook me up. I voted for you!
