I'm brewing 2 different batches a week apart that both call for the same yeast. I dont know the target OG for either, but I do know the projected ABV for one is ~7 and the other is prob ~9.5-10. My plan was to pitch vial of whitelabs to a 1L starter (~1.040) a week before and ferment out completely on stir plate and once complete remove from stirplate and immediately divide in two sanitized mason jars. For the lower grav I was gonna make another 1L starter from slurry from one jar and for the higher I was gonna pitch slurry to a 2L starter. Would this be under-pitching? I'm reading all the washing threads so after these batches I'll have plenty of yeast from here on out.

Why not just make a 2L starter for the first beer with the vial. Pitch that, then use your wine thief to get a cup off the top of beer one a few days before Beer 2 brew day, and make a 2L starter with that for beer two. When Beer 1 is done (moved to secondary or bottled), then get your mason jars and yeast washing instructions, and use the slurry to harvest the yeast for future batches.

Thought John Palmer and most threads I read on washing/saving/ranching says to wash from secondary.

I'd make a two liter starter and keep 10-20% of the starter in a sterilized mason jar. Then use this to make your second starter. Seems simpler than taking the yeast from a carboy or ale pail

I split off starters too, but not washing yeast is like poring money down the drain.
