Yeast Starter Calculators/Models
Posted: Wed Nov 02, 2022 11:10 am
I am aware of two calculations for yeast starters. There is the Chris White/Jamil Zainasheff model and the Kai Troester models (https://braukaiser.com).
I'll will not get into the details of each model, I'll leave that for you to research. I did read about both and I agreed with Kai's conclusions.
Empirically I would run my own test with yeast starters and count yeast cells. Maybe that could be a club project.
Beersmith only has the White/Zainasheff calculator. I use these two online calculators that both have the W/Z and Braukaiser models: What are your thoughts on yeast starters? Which model do you use?
- The White/Zainasheff model is based on a diminishing return where adding more starter wort ultimately gives you no more yeast growth.
- The Braukaiser model produces more yeast with the more wort available in a linear fashion. (Blog post: http://braukaiser.com/blog/blog/2012/11 ... st-growth/)
