Yeast starter chart

[gopher_brewmeister]

I’ve been unsuccessfully looking online for the yeast starter chart that shows how many hundred billion yeast cells in a certain volume of starter propagates a certain amount of yeast after 24 hours. I’ve seen the chart, I just can’t find it anywhere. I’m doing a 1.060 American Pilsner and need to do a step starter to propagate the correct amount of yeast to pitch. I just can’t find how much volume I should use for my 2 steps with a 2L flask and 2 smack packs of yeast. I’m guessing it’s around 1600ML with 2 smack packs for the first step, decant and then add another liter or so fresh starter to the flask to get my 450 bil. cells.

Anyone out there know what I’m talking about?

Thanks.

FWIW, I ran it through MrMalty and with a stir plate it’s recommending a 2.2 L single-stage starter. You should be fine with just filling the flask as much as you’re comfortable. 3.4 L with “intermittent shaking”, so you could also just use a gallon jug. I wouldn’t want to do two stages when I only needed to slightly more than double the cell count.

You should also be prepared for some blow-off with this scenario (as has been my experience), so a little fermcap might be helpful.
