The shelf life of matcha can depend on various factors, including how it is stored. Generally, matcha retains its best quality when stored in a cool, dry place, away from light.
Here are some guidelines regarding the shelf life of matcha:
1. Unopened packaging: Unopened matcha can generally be stored for up to a year or longer, depending on how it is stored. It is important to observe the best-before date printed on the packaging.
2. Opened Packaging: Once opened, matcha should ideally be consumed within 3-5 months to ensure optimal quality and freshness. It is important to reseal the packaging tightly after use and protect the matcha from moisture, air, and light.
3. Quality and Taste: Over time, the quality and taste of matcha can deteriorate. Aging matcha may lose its vibrant green color and fresh flavor, and may develop a bitter taste. If the matcha starts to lose its freshness or develop unpleasant flavors, it is probably best to discard it.
