I am going to try to harvest yeast for the first time new week.
1) I have a batch of Pale ale that has been in the primary fermentor 3 weeks and I just wanted to confirm that there should still be dormant viable yeast after that length of time. The yeast is the Wyeast 1968 London ESB.
2) I plan on brewing 2 different beers, a high gravity IIPA and then a low gravity session beer. I was reading Palmer's chapter on pitch rates and calculating yeast cell counts of starters. How do I determine the original yeast cell count of my harvested/washed yeast so I can prepare the correct starters for each of the beers?
