Does Tea Expire?
YES, but it depends.
The Zen's Tea House position on tea expiration is: "it depends. If the tea is stored in a cool, dry place then it will last for at least a couple years." One of the reasons that Zen's Tea House tea is recognized as having higher quality tea is that we sell our tea within a few weeks of receiving our shipments. Time is a factor. Our advice is trying to infuse your tea with newer fresher teas. Tea blending is a great way to utilize tea that is below standard.
