It can typically last for about 1 to 3 years when stored in a cool, dark, and dry place in an airtight container. However, its shelf life can vary depending on the freshness of the individual spices and the quality of the storage conditions. To ensure the longest shelf life and best flavor, it's a good practice to label the container with the date it was made and to store it away from heat, light, and moisture. If you notice any changes in aroma, color, or flavor, it's best to replace it with a fresh batch.
