We are gearing up to brew our first batches and I plan on using dry yeast as a house strain.
Running calculations on dry yeast pitch rates is very frustrating, as no one seems to know what true cell counts are for dry yeast. It seems to run anywhere from 6 bil cells/g to 20 bil cells/g depending on where you look. The 6 billion cells is the guaranteed cell count from Fermentis, while 20 billion comes from Jamil's "Mr. Malty" pitch rate calculator, without clear documentation. My calculations led me to plan on a 500g brick (of US-05) for each of our 5BBL batches, but now I see other brewers pitching that amount for 10BBLs, and half that for 3BBLs.
Assuming 14*P (1.060).... any advice?
