Store your Matcha Powder in an airtight, opaque container in a cool, dark place like the fridge or freezer to preserve its vibrant color, fresh flavor, and nutrients. Avoid direct sunlight, heat, humidity, and odors—oxygen, light, and moisture are its main enemies.

• After opening, use within 30–60 days for best quality; let refrigerated matcha reach room temperature before scooping to prevent condensation.
  

• Do not leave it unsealed or in clear jars on the counter, as this speeds up oxidation and dulls its taste.
