For optimum flavor, store herbs and spices in clean, airtight containers away from heat, light and moisture.
As a general rule, herbs and ground spices will retain their best flavors for two years.
The back panel on our square jar has a "date opened" panel for your convenience in managing your spices. Our all-natural soup bowls and reduced sodium soup cups are best when used within one year. Proper storage will help maintain freshness.
