I have yeast in a growler from a previous 5 gallon batch (pale ale). Brewing a porter now and want to reuse this yeast. I poured the trub and yeast into the growler (wasn't that much hop residue).

Should I pour all of the contents in evenly between my two 5 gallon batch of porter? I believe I heard from Palmer that 1/3 cup of slurry would be enough.

Take a look at the yeast washing sticky, that would be the way I would go to get the best yeast in.

Yeast rinsing is a waste of time. Pitch the correct amount (see and it will work great even with the hop flavored trub in it. Washing is done with phosphoric acid and only worthwhile for irreplaceable yeast.

For normal gravity beers (under 1.060) I just use a half cup of fresh slurry. If my slurry is a few weeks old I'd use twice that much. Pitching correct amount will add no noticeable color or flavors from the slurry. The dead yeast and trub fall to the bottom. The live yeast get busy multiplying. You end up with a nice heathy generation of yeast doing the work.
Everything is better with a beer.
