I have a few vials of white labs yeast that are 10-11 months old. I plan on making a starter to see if they're still viable, and then stepping them up if so. My question is what size starter should I use for the first step? There seems to be a lot of conflicting and unsure information about long term yeast viability, and I want to make sure the inoculation rate isn't too low for the first step. Or does it even matter for the first step?
