What temp is too high for yeast?
Water at 81° to 100°F is the optimum temperature range for the fermentation process. Water at 95°F is the fermentation temperature that yields the best result. Water at 140°F or higher is the kill zone for yeast. At temps like this or higher, you will have no viable live yeast left.
What is the correct temperature for fermenting yeast?
The optimum temperature range for yeast fermentation is between 90˚F-95˚F (32˚C-35˚C). Every degree above this range depresses fermentation. While elevated temperature is problematic in all phases of ethanol production, it is specifically hazardous during the later stages of fermentation.
What happens if I pitch my yeast too cold?

What temperature kills yeast in dough?
Water below 70°F may not be warm enough to activate the yeast, but rising the dough in a warm room will activate it-it just might take several hours. Water that's too hot can damage or kill yeast.
