Yes. I have seen cakes of fresh yeast become moldy. Fresh yeast has a very short shelf life.
Yeast need warm temperatures in order to grow. The perfect temperature for yeast is about 110 degrees F. Yeast will not start to reproduce and rise without warm temperatures to activate it.
The shelf life of yeast is typically around 1-2 years if stored in a cool, dry place. Once opened, yeast can be stored in the refrigerator for up to 4 months before it expires.
Directly regulated by sugar and salt. Sugar cuases yeast growth, salt slows. Environmental factors such as moisture, heat and acidity also affect yeast growth.
Letting a water, sugar, and yeast mixture ferment for a long time does not affect the quantity of ethanol produced.
