                                Yeast is a living organism that is particularly sensitive to its environment, and water is a key component for its activity. But does water deactivate yeast, or is it more complex than that? The temperature of the water is the single most critical factor, determining whether the yeast thrives, enters dormancy, or is killed completely.
