How Long Can Matcha Stay Fresh in the Fridge?
Preserving the vibrant color and earthy notes of your matcha powder.
Matcha remains high quality for up to 2 weeks when stored in an airtight container in the refrigerator.
Matcha is a delicate powdered tea that is highly sensitive to environmental factors like light, heat, and moisture. When exposed to air, it begins to oxidize, causing its vibrant green color to fade into a dull olive or brown hue. To maintain its signature umami flavor and smooth texture, proper storage is essential. While matcha can stay safe for much longer, its culinary peak is relatively short once the seal is broken. Keeping your powder in an airtight container within a cool, dark environment like a refrigerator helps slow down this degradation process significantly.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
Is old matcha safe to drink?
Yes, matcha remains safe to consume even after it loses its vibrant color. Sage's Verdict: While it won't hurt you, the flavor profile will be significantly flatter and less vibrant as it ages.
Why does my matcha turn brown or lose its color?
Oxidation caused by exposure to air and light breaks down the chlorophyll in the leaves. To preserve its vibrant green color and flavor, always store your matcha in a dark, airtight container.
How should I store matcha to keep it fresh?
To maintain peak quality, store your matcha in an airtight container kept in the refrigerator. This method keeps the powder fresh for up to 2 weeks.
Can I freeze my matcha?
While you can freeze matcha, it is not necessary if stored correctly in the refrigerator. If you choose to freeze it, ensure it is in an airtight container to prevent moisture and air from degrading the quality.
To keep that vibrant green glow, treat your matcha like a precious gem: keep it cool, dry, and tucked away from the light!
