I don't know whether to believe MrMalty. Does he account for yeast growth in the beginning stages of fermentation when the yeast consumes the oxygen and propagates?
I always try to follow his advice but even when i under pitch based on his calculation i have complete clean vigorous fermentation.
Let's assume i have 50 ml of yeast slurry with 2 billion cells per ml at 100% viability.
I want to make 5.7 gallons of lager beer at on OG of 1.055
He says i need 437 billion cells. If i use a wyeast smack pack or white labs vial i would have to have a 4.34 litre starter.
If i use my 50 ml yeast slurry which should be the equivalent in yeast cells as a wyeast pack or white labs vial then I would be short 168 ml of yeast slurry.
So based on my very shabby logic does that mean my 50 ml slurry should be able to grow into a 218 ml slurry with a 4.34 litre starter?
Pardon my language but that seems f'in impossible.
