How much dead yeast

[superstock]

For the sake of the thread let's say we have fermented a straight K&K. (so no discernable trub)
After the yeast has flocced out, how much of the yeast cake is dead yeast ?
Also would there be a difference between an ale and a lager ?

Depends on how long it has been sitting there. I don't make a habit of it, but I checked a two week old ale yeast cake that had been kept cold - that one was 70% dead. Time, temperature, and alc % would be the main factors I reckon. Lager yeasts are more delicate than ale yeast I find.

Dunno how much physical volume proportion is yeast in your case.

Presuming you have just decanted the beer.
