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.
