yeast dies at what temperature
The minimal alcohol product burns off during the baking process, and the yeast dies also with the heat. The ideal temperature for yeast growth is 100 to 115 degrees F., but for leavening purposes, the ideal temperature is 80 to 95 degrees F. If the yeast grows too quickly, it will produce large bubble pockets in the end product. Yeast begins to die at 120 degrees F. So, it is important to let your yeast dough rise in a spot where the temperature is regulated. One-half an ounce of yeast will raise 4 cups of flour in about 1-1/2 to 2 hours, under ideal conditions. You should also proof your yeast to be sure it is viable before using in a recipe.
