This year I am looking to expand my knowledge on yeast. I am looking to start counting cells and test for viability. My current project is to determine growth in a starter to be sure I have the required pitch amount.
I am planning on brewing an Marzen with a OG of 1.055. Yeastcalc states I need 423B cells. According to the calculator I should end up with 455B cells at the end of my starters for a total of 455B cells in a final 2.5 liter starter.
So for my dilution schedule:
I have 455B cells in 2.5 liters
I need a dilution to be ~150 cells per ml to count the cells
So to check my math here is what I have for my dilutions:
455B/2500ml = 1.82B per ml
10:1 dilution = 182M per ml
1000:1 dilution = 182K per ml
1000:1 dilution = 182 per ml
Does this look right?
