Call the yeast coming out of the fermenter Generation 1.
I’ve never concerned myself with ‘viability’. I store the yeast in a mason jar. When I want to use it again I make a starter and spoon 2-4 scoops out of the jar. Works for me.

So the first harvest is generation 1 then when I pitch that and harvest I’ve harvested generation 2?
I am so new at this it is pathetic, but am trying new things, so here is my 2 pennies;
The dry pack is Gen 0.
The first harvest from gen 0 is gen 1.
And so on…
I have about a liter of Danstar Windsor in the fridge that I just harvested and washed from the 1 gallon Whitehouse honey ale I did. Looks god, but I am short on glassware, so i have it in two laboratory jars I have. The second one I filled from my wash vessel looks like I may have got a little of the hoppy trub in there, and I am thinking of dumping it out.
Let’s say I have a 2nd gen in a mason jar that is going on a few months old, so I freshen it up with a starter. Do you now call it 3rd gen or keep it at 2nd gen?
My 2¢ not that it matters the vial is 1st generation. The starter is then 2nd so what you harvest from your beer is 3rd. Unless you do a two step starter then it’s 4th. I go many generations without any problems. I hardly ever do starters. Don’t see any advantage of making a starter from saved yeast .
My 2¢ not that it matters. To me a generation is how many times the yeast went through the stress to ferment a beer. Fermentation stresses and subsequent harvesting method may have more of an affect, if any, on the yeast more than fermenting a starter wort.
The yeast propagated with a new pack of yeast and the over build harvested from the starter is generation 1. Yeast harvested from a fermented beer is generation 2. When this yeast is harvested from another fermented beer it is generation 3.
I have so much harvested yeast that I’ve given up trying to track generations. I’ll rebuild a 4 month, or so, old yeast If I have only one container of that yeast strain. I’ll then store this yeast from the fresh starter in two containers in case one shows infection.
