How Long Does Yeast In A Jar Last?
The longevity of yeast in a jar depends on the storage conditions and the type of yeast. Generally, dry active yeast can last for up to two years if stored in a cool, dry place, while instant yeast can last for up to three years. However, once the jar is opened, it is recommended to use the yeast within six months and store it in an airtight container in the refrigerator or freezer to prolong its shelf life.
