Title: Yeast Starter
Post by: tom_hampton on November 22, 2011, 10:33:31 PM
There are two things I care about when creating a starter:

1.  How much starter do I need to grow. ---already provided by beersmith
2.  What is my starting starter size.

According to Chris White yeast starters should have an initial concentration between 50-100 mil/ml.  So, that drives my initial starter size...based on my yeast slurry amount and viability.

Since I use a stir plate, with each step, I can triple the starter size until I reach my target volume.  I think the formula is really 2*stir-plate-factor.  I use 1.5 for the stir-plate factor since that most closely follows all of the available data.

The starter calculation needs the ability to allow multiple steps.
