To keep your matcha fresh and flavorful:
- Store it in an airtight container
- Keep it in a cool, dry, dark place
- Avoid heat, humidity, and direct sunlight
For best flavor, use within 4–6 weeks of opening—especially if you’re using it for sipping (culinary uses are more forgiving).
Pro tip: you can refrigerate matcha if you're in a humid climate—just make sure the container is tightly sealed!
