Yeast Cake Viability

[NoVaBrewer]

I've recently brewed a double IPA using SanDiego Super Yeast I've racked out of the Primary leaving behind about 6" of beer on the Trub.

I've left this in the Carboy for about 3 weeks at 35-45F.

How long could this be viable, given that i pitch to a new starter and nourish for a day or two before I reuse it.

Thanks All

It depends on the ABV level of the beer.

The final beer is around 8% ABV
