For bakers, yeast is one of the most important ingredients. That’s why proper storage is essential to prevent it from degeneration.
Most people store yeast in transparent packages and leave it exposed to sunlight or in a hot storage room without knowing these conditions can kill the yeast. Even when left at room temperature, it’s still very risky. The right way to store yeast is to keep it in an opaque container and in cool places like a refrigerator.
Now that you know how to properly store yeast, how do you test if it’s still working?
It’s actually really simple. All you have to do is mix warm water with a small amount of sugar and add your yeast to it. If your yeast is alive and still working, it will become fluffy. If it’s dead, it will dissolve in the water and stay still.
