Yeast cake life span

[Madmannvan]

I have a batch of beer fermenting in a corny and plan to transfer to a secondary keg on a Thursday, then use the yeast cake for a brew on Saturday. If I leave the cake sealed in the keg for a couple days will it be useable? I will be be transferring the beer with a sealed transfer keg to keg.

Sure it will be fine. Are you using the full cake or harvesting and repitching?

I figured when I push the beer to the secondary keg the first bit will be yeast at trub so I was going to collect that in a jar until it runs clear then transfer the rest of the beer off to secondary and use what yeast is left below the dip tube for the next batch.

Sounds like a good plan. I meant to ask if they were similar beers? If so, all good

Same beer, second batch has a couple tweaks. Going to do a side by side, one with nothing added to the water and one with cacl/gypsum added
