We can’t control how fast you’ll go through your seasonings, but the shelf life of Dash of Dacy seasonings if opened is typically up to 18 months. Unopened seasonings can last up to 2 years.  All seasonings opened and unopened should be stored in a dry, cool, and dark place, preferably a cupboard.To ensure the Dash of Dacy blend is still fresh, give it a smell. If the aroma is potent, then your dish will be full of flavor. If you can barely smell the goodness then the blend is still okay to use but may not flavor you food entirely - it may be time for a replacement.
