Tea has a shelf life like all food and like all foods, each tea varieties shelf life will vary.
Teas natural enemies are air, light exposure and moisture or humidity.
The best place to store you tea is in a cool dry place such as the pantry and in an air tight container or re-sealable bag.
If using a re-sealable bag it is wise to expel the air prior to re-sealing.
You may not be aware that tea can absorb strong odours from foods, so once again keeping them in an air tight container can assist in keeping your tea as pure as the day you purchased it.
It is not a good idea to store you tea in the fridge or freezer as it will deteriorate the tea very quickly.
If you don’t have a suitable container or are unsure of how best to store your tea if you live in a high humidity area, it is best to ask the store you purchased your tea from or email email@example.com for further advise.
