In other words, what is the maximum temperature of water I can use in yeast bread dough? I don't proof the yeast, I use active dry yeast and I just add it to the other ingredients and knead it in.

There are multiple temperature points per yeast family might be of Interest:

  • The growth limit temperature, see this paper. It indicates as high as 45°C for some and 20°C for others.
  • 'Injury' temperature (for bread and brew generally thought be around 120°F)
  • Death temperature.

Keep in mind for bread: Bread Yeast at higher temperatures produces off-flavours that may be undesirable to your goal. If you are trying to speed up your dough, you may want to add the yeast to water with some food and let develop for a while before mixing in the flour.

Although I intentionally didn't include this in my question, I am experimenting with how fast I can make a standard loaf. My goal right now isn't quality, but speed. Your info is helpful towards that. –  Jolenealaska Jan 20 at 18:12

@Jolenealaska the fastest yeast growth doesn't occur at the highest temperature, yeast has an inverted-U-shaped growing curve. Use 35 Celsius, soft dough and added sugar for highest speed. –  rumtscho Jan 20 at 20:04
    
    
@Jefromi It's not really the same thing, I wanted the answer to the question because I am experimenting with the issue. That's why I didn't include the "why" in the question, or ask how I can get the fastest possible rise. The question was written to help me set up parameters for experimentation. –  Jolenealaska Jan 20 at 22:10

Different strains of yeast have varying tolerance temperature, on both the high side and the low end. As a 'general rule' 110°F is a safe high temperature.

Yeast is happiest at around body temperature - 37°C. The higher you get, the more damaging it will be to the yeast. 30 or 40°C would be fine, but 50°C probably won't (though some yeast might survive). 60 or 70 would definitely kill the yeast.

But for bread dough there's no reason to use a high temperature. I'd mix the water from the hot and cold taps to get something that feels comfortably warm when you put your hand in it, and you should be fine.
