The flavor experts at McCormick recommend the following tips for checking your spices freshness:

• Check to see that the color of your spices and herbs is vibrant. If the color has faded, chances are so has the flavor.
• Rub or crush the spice or herb in your hand. If the aroma is weak and flavor is not apparent, it’s time to replace it.
• Store herbs and spices in tightly capped containers, and keep away from heat, moisture and direct sunlight. Replace bottle lids tightly immediately after use.

If you have McCormick spice in rectangular tins, except for black pepper, the spices are at least 15 years old!
