Matcha, a green tea variety, is well-liked for its distinct taste and health advantages. It is made from shade-grown tea leaves that are stone-ground into a fine powder. The powder is then used to make tea, smoothies, and other foods and drinks. 

But, like all food products, matcha does have a shelf life and can expire.

Does Matcha Go Bad?

Yes, matcha powder can go bad over time. Oxidation of tea leaves leads to the degradation of powder and loss of flavor and strength. The oxidation process can be accelerated by exposure to air, light, and moisture, so it is crucial to store matcha properly.

How Long Does Matcha Last?

Matcha’s shelf life depends on its original quality, storage methods, and production date. Typically, properly-stored, high-quality matcha lasts up to 2 years after manufacture. On the other hand, low-quality matcha might last only several months.

  3. Clumps or lumps: If the powder has clumped together or has formed lumps, it may have gone bad.
