Ah, good!
Here's what I get, using 01/29/23 as the yeast packaging date, but with only
6% decline in vitality per month (PurePitch yeast), for a total of 18% over the past 3 months. I therefore manually entered 82 (100-18) into the [Viability %] box.
So I do not think you grew enough to pitch three different batches. You might have enough for two ok pitches or one solid pitch.
Exactly!
Since most of the yeast is now freshly made, you can probably pitch half (one and a half jar) of your newly made starter, and save the other half for next time of better, to make another starter and pitch some of that. And so on.
Or make a 24-48 hrs
vitality starter with one of the jars plus 1 liter starter wort. Pitch as is, do not cold crash/decant.
Therefore, if you can, making
1.6-2 liter starters would be more productive. For example, here's the 2 liter version:
That's enough for 2 solid 5 gallon pitches of 1.060 wort. And always save some out to make a next starter round from. Especially in these days where a sleeve of yeast now runs around $12. Plus shipping if you can't get it locally.
