Tea absorbs moisture and other aromas very easily, so it's important that tea is stored in an airtight container, away from strong-smelling items. Most tea stores well up to a year, but it depends on many factors.
Loose tea should be stored in a cool, dry, airtight, opaque container. Tea tins with tight-fitting lids are ideal. Do not store loose teas in the freezer or refrigerator.
The lifespan or shelf life of tea is always different depending on how the tea is stored, what kind of tea it is and other factors — however, most teas should store well for up to 1 year.
