What is the minimum temperature yeast will be active?
We all know that warmer temperatures mean more yeast activity (provided a food source), and that yeast survives freezing, but what is the minimum temperature yeast can perform fermentation?
As I gently warm a dough from freezing, what temperature will it start to rise? 10°? 15°?
Another way of asking this is, how cold does my dough have to be to stop rising?
Best Answer
It will even rise (very, very slowly) at refrigeration temperatures (4C, 39F). For it to completely stop rising you need to freeze it (or very close). A lot of recipes call for the dough to rise overnight in the refrigerator. Depending on the dough, it may it may in fact completely rise in the refrigerator overnight. Long rises create more flavor than short ones, often speed is not of the essence. Frozen dough will start (slowly) to rise as soon as it starts to thaw.
Never judge readiness by time. Temperature is only one of many factors that will vary from loaf to loaf.
Volume is the main indicator of readiness (usually double the "pre-rise" size). Also, there's the poke test. Stick a couple of fingertips a centimeter or so into the dough. If the indentations remain after your fingers are removed, that's an indication that the dough has risen enough.

Quick Answer about "What is the minimum temperature yeast will be active?"
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 lowest temperature yeast can survive?
As a general rule, yeasts will die between 105 and 108 F. During fermentation this terminal temperature will lower as a result of alcohol presence. As a wine approaches 10% alcohol content, the terminal temp for yeasts can be as low as 90F.What temperature does yeast become active?
100\xb0\u2013110\xb0F is the ideal temperature for Active Dry Yeast. 120\xb0\u2013130\xb0F is the ideal temperature for RapidRise\xae and Bread Machine Yeast. Liquids help bloom the yeast, and the right moisture levels can dictate a bread's final texture.Does yeast work at low temperatures?
Yeast cells are naturally cryo-resistant and therefore able to withstand cold temperatures. They possess an incredible ability to adapt to the cold.BASIC FOR BEGINNERS: HOW TO ACTIVATE YEAST | RIGHT WAY TO ACTIVATE THE DRY YEAST
