[Storage method] Matcha / Green tea is fine for one or two years if kept in the refrigerator. If kept in the freezer, its freshness will be preserved indefinitely. However, if left in a cool, dark place, the color and taste will change in 3-4 months, especially in the summer. Also, even if kept in the refrigerator, Matcha / Green tea easily absorbs scents, so please be careful not to store it with strong-smelling items as the smell may transfer. Therefore, the expiration date is just a “guide” when stored in a cool, dark place.
