I've recently harvested yeast from a Rogue Brutal Bitter using the cool new stir plate that I made via the help of this forum. Now I'm wondering how I can tell how much yeast I've got.
I started with 1 cup of water and an ounce of DME. I added to that, the last couple ounces of the beer after shaking it enough to free the yeast from the bottom of the bottle. A couple days later, it was pretty obvious that the yeast was doing it's thing and multiplying.
What I want to know, is how to tell what the cell count is after the fermentation is complete. Since the first addition of wort, I've twice added the same water/DME combo to the yeast. How can I tell when I have enough to pitch in to a batch of brew?
Also, I want to start a yeast bank, and build starters from smaller vials of yeast. How will I know when I have enough?
TIA,
Scott
