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.
For thousands of years tea connoisseurs have sought to prevent their tea from going bad. Often prolonged exposure to light, excessive amounts of heat & air are the most common factors leading to expired tea. Teas like Puerh & Golden Milk have a much longer life span the traditional Green teas. Would you like more information?
