This is my first post, I just registered after reading about 50 pages of yeast starter threads because I wanted to join the conversation. It seems Mark is gone now?
When propagating a starter, do we assume a well-oxygenated (dare I say SNS) starter will always reach maximum cell density of 200b cells/L if the inoculation rate is reasonable?
I've got a 100-day-old pack of 1764 that I'm going to start with 2L of 1.040 wort for an 11 gallon CDA (two 1-L starters each with half a pack of yeast). Assuming a high-end estimate of 20% loss of viability per month, I figure I can reasonably expect 50b live cells total, or 25b per starter jar. Is it safe to also expect that I'll reach that max cell density of 200b cells in each starter after 3 doubling times of 90 minutes, plus a little while to get rolling after inoculation?
