I usually use liquid yeast so this is process is new to me. Both How to Brew and the Fermentis website say to rehydrate in warm water (95-100F in HtB, 77-84F for ale and 69-77F for lager on Fermentis). Okay, got that. Both sources say wait 30 min then pitch. So the question is, do I pitch the still warm yeast into a much cooler wort? If I just pitch as is, it's going experience a roughly 30F drop in temp. Will this not shock the yeast and cause more harm than good? Or, should I wait the prescribed 30 minutes then cool the yeast down closer to the temp of the wort?
