Yeast cells die (thermal death point).
120° F130° F (49° C55° C)
Water temperature for activating yeast designed to be mixed
with the dry ingredients in a recipe.
105° F115° F (41° C46° C)
Temperature of water for dry yeast reconstituted with water
100° F (38° C)
or lower When yeast is mixed with water at too low a temperature,
an amino acid called glutathione leaks from the cell
walls, making doughs sticky and hard to handle.
95° F (35° C)
Temperature for liquids used to dissolve compressed yeasts.
80° F90° F (27° C32° C)
Optimum temperature range for yeast to grow and reproduce at
dough fermentation stage.
70° F80° F (21° C27°C)
Recommended water temperature for bread machines.
40° F (4° C)
Recommended refrigerator temperature. Used directly from the
fridge, yeast is too cold to work properly.
