While calculating what size starter I need for an upcoming Baltic Porter, I ran into some confusion as to how I should classify the WLP810 "San Fracisco Lager" yeast considering its warmer fermentation temperature range compared to other lager strains. I emailed the folks at White Labs and received the following information:
I was a bit surprised, I was going to cool to lager temps BEFORE pitching.
We recommend pitching lager strains at 70 deg F and then dropping the temperature down once the fermentation gets going.
In this case, you can treat it like an ale strain and do the same size starter.
