I'm freezing some 1 liter water bottles to add to it to chill it down, but they aren't frozen yet. (I wish I had thought of them earlier) I'll be pitching K-97 yeast. Pitch it warm and add the sanitized ice bottles in the morning, or wait until tomorrow to pitch? It's in a sanitized brew bucket right now with a sanitized lid snapped on tight. I moved it to my basement utility room where it's cool.
