Herbs and Spices do not expire in-the literal sense of it: herbs do not truly expire or go bad in the traditional sense.
When a spice is said to have gone bad, it simply means that it has lost most of its flavor, potency, and color.
Dried herbs typically last 1 to 3 years.
Ground, or powdered, spices typically have a shelf life of 2 to 3 years.
Common examples include:
- powdered ginger
- garlic powder
- ground cinnamon
- chili powder
- ground turmeric
Fortunately, consuming a spice that has gone bad is unlikely to make you sick.
It is still generally safe to consume dried herbs and spices that are past their prime, although they wont add nearly as much flavor as their fresh counterparts.
The degradation rate of herbs depends also on storage conditions
Dried herbs and spices will last the longest when stored away from air, light, heat, and moisture.
If there is an odd smell coming from your herb, musty, moldy or presence of bugs- Its time to throw it out even if its still flavorful.
Kick-off your sustainability effort and compost herbs way past their best before dates.
