How old is too old

[Dr Jacoby]

I hate pitching all the liquid from a starter into wort (especially if it's into pale wort). But I also don't like the idea that by decanting away most of the liquid I might be wasting lots of healthy yeast still in suspension. One option to help address this concern is to crash cool the starter the night before brew day to help the yeast settle out. Does this method pose any risks in terms of shocking the yeast? If so, is there an alternative method available? Is this even something to be worried about (i.e. maybe the yeast sludge in a starter is more than enough to pitch on its own without the liquid portion?)

I heard him talk in this one. Very interesting.

I was about to ask where could I track this down but sure I'll hopefully get to ask him in person next weekend

It's an interesting answers and one I certainly hadn't thought of...but I'm not a doctor.

If it's not too late to add something...

I'd like to hear the man talk about ways in which to combine yeast strains in order to get interesting and unique beers.
