What’s the big deal about checking water temperature?
A. Yeast is a living organism. If the water is too hot, the yeast will be killed . If too cool, more time is required to develop best flavor and texture. The ideal temperature is 120° to 130°F. (Most home faucets will get water this hot after running it for a minute or two.) Because the kill point for yeast occurs at 140°F, we recommend using a thermometer for best results.
