Can matcha powder be stored long-term?

Matcha powder cannot be stored indefinitely. Unopened, it maintains good quality within the expiration date (typically 6-12 months). Once opened, due to easy oxidation and moisture absorption, its flavor and nutrients degrade rapidly. It's recommended to use it within 1-3 months after opening.

Best Storage Methods

To extend shelf life and preserve freshness, follow these methods:

• Light Protection: Store in an opaque container away from direct sunlight or strong light.
• Airtight Sealing: Use a sealed container or vacuum packaging to minimize air exposure and prevent oxidation.
• Refrigeration or Freezing: After opening, store in the refrigerator (around 4°C) or freezer (-18°C). Ensure the container is completely sealed to avoid condensation from temperature fluctuations.
• Dry Environment: Keep in a cool, dry place with humidity below 60% to prevent moisture absorption and clumping.
• Avoid Strong Odors: Store away from strongly scented items like spices or coffee to prevent odor absorption.
• Use Promptly: Prioritize using opened matcha and regularly check for discoloration or unusual odors.
