The average shelf life for tea bags is about 18 months. There is a two-year shelf life for instant tea and loose tea that is packaged properly.
When it comes to the shelf life of tea bags, it only counts for the taste of the tea. Tea bags don't generally have health concerns or dangers if consumed after the shelf life recommendation. Tea bags store best when kept in air-tight containers.
Label the containers to make it easier to remember when to throw them out and purchase fresh ones for the best-tasting tea. Store them in the pantry to keep them cool and dry. It is best to store tea bags away from other foods that cause an odor.
