In general, tea that is properly stored has a long shelf life. Some teas are definitely better when freshest, however others may taste better with age (black teas in particular). We put best by dates on our packaging for each tea. In general, pure teas usually have a shelf life of 2-3 years. Blended teas (depending on the ingredients) are also usually good for 2 years. Flavored teas have a little less shelf life, but in general they will be good for up to 1 year. Make sure to store your teas in a cool, dark, dry place for best shelf life. Properly stored teas will be good for a very long time.
