Thank, will use the yeast calculator next time. The White Labs yeast package had an expiration date of Dec 4, 2014. Don't know when the yeast was made or the viability. The yeast calculator looked a bit daunting but can see how knowing the viability will help you reach the yeast cells you need for the beer you are making.
As I said before, White Labs said to use a 1000 ml ( 1 quart ) starter. Beer Smith said to use a 2 qt ( about 2000 ml ). What I missed in the BS yeast volume, not viability, calculator was the following:
The beer I am making needs 383 billion cells. With a 1000 ml starter you get 226 billion cells. With a 2000 ml starter you get 360 billion cells. I have a 2000 ml flask so will use the yeast calculator next time
