Storing un-opened packaged tea in the refrigerator is a good idea. Before use, however, please allow enough time for the tea to return to room temperature before you open the bag, this avoids temperature shocking the tea. A sudden change in temperature can cause condensation in the bag, potentially degrading the tea through moisture. We recommend, therefore, that you store your unopened tea package in the refrigerator but once it is opened, store it in an airtight container in a cool, dry, and dark location.
