How to Store Yeast?
Yeast is known as a microorganism that becomes less active with time. So, you should take great care of it.
If you bake things regularly, then you may use yeast regularly. But if you bake things after intervals, you need to store the yeast to remain fresh when you use it another time. The shelf-life of yeast will be increased if you store it in good conditions.
If you have bought too much yeast for baking purposes and are planning to store it for a longer period, you need to take care of its storage conditions. Some important storage guidelines for yeast are given below.
Place in a cool and dry place
You should store an unopened package of yeast in a cool and dry place. The best place for storing the unopened package of yeast in the cupboard of your kitchen.

Once you have opened the dry yeast package, always keep in mind that you should not keep it at room temperature for too long. It should be stored in the refrigerator so that it can retain its quality for a long period.
It will be best to keep it in an airtight container to store it in the refrigerator or freezer. The same is the case with the cake yeast. It should be wrapped tightly and should be stored in the refrigerator.
