Basic Yeast Questions

Go for it. I'm just trying to understand the details but then use a simple method that does the job. I might fiddle with it in certain styles to boost esters but if I do it will be from understanding rather than lack of or accident

I hear ya, but the white labs lady says 1000ml is waste of time

For what it's worth, the numbers from the NHC presentation are *much* lower than what I see in 1 L starters. I've found that 100 billion cells per liter of 8°P wort (stirred) gets me within 30% every time.

Now I wish I'd gone to that seminar instead of whichever one I picked instead... It would be nice to have all the parameters of Neva Parker's experiments.

She's not the only one.  My understanding is that if you make the starter too small there's not enough food for the yeast to rebuild their glycogen reserves  DISCLAIMER:  I am not a biochemist!

Sean, just to clarify, you're saying 100 billion cells in an 8p 1 liter starter is getting you within 30 percent of desired pitching rate?

[a10t2]

Yeah, that wasn't at all clear... 100 of growth, ~200 billion total from a pack in a 1 L starter.
