Expiration & Storage Tips
When does spice rub expire?
Unopened, a store-bought spice rub can last between 2-3 years. Just remember to check the printed date on the package. For homemade spice rubs, it's best to use the rub within 6 months while the spices are still potent. Once a spice rub has been opened, it's best used within 6 months to a year, depending on the freshness and quality of the individual spices in the rub. If it's been frozen, once defrosted it should be used within few weeks.
How do you tell if spice rub is bad?
You'll know that your spice rub has gone bad when the color fades and the aroma weakens. Fresh spice rubs are vibrant in color and have a strong, hearty smell. The key to recognizing when a spice rub has past its prime is in the aroma. If you give it a whiff and there's hardly any scent, or if it smells off, it's probably best to toss it. Also, if your spice rub has clumps or visible signs of moisture, it's probably gone bad.
Tips for storing spice rub to extend shelf life
• Always store your spice rubs in a cool, dry place. The pantry is perfect. On the counter under direct sunlight or near a heat source like the stove or oven is not ideal.
• Use airtight containers for storage. This can be the container it came in if it's store-bought, or your own airtight containers if it's homemade. When storing, ensure the lid is always on tight to keep moisture and air out.
• Consider purchasing smaller quantities of spice rubs, or making smaller batches of homemade rubs. This way, the spices will be fresher and more flavorful when you use them.
• If you don’t think you’ll use the rub in a while, you can freeze it in an airtight container or freezer bag. Just remember to label it with the freeze date!
