Why not pitch dry directly out of the refridgerator like Tubercle does.
Ummm, selection?
I was refering to the OP's delimma of hydrating yeast and concerrn of yeast slurry temp vs. wort temp.
I select the yeast I'm going to use out of the refrigerator and sprinkle on the cooled and aerated wort.
I don't understand your comment/question.
