Matcha Storage

Matcha is sensitive to light, heat, air, and moisture. Proper storage is important because matcha can quickly lose its bright green color, aroma, and freshness.

How to store matcha properly

Keep it airtight

Store matcha in a tightly sealed container to limit oxygen exposure.

Protect it from light

Use opaque tins or dark containers. Sunlight can speed up oxidation.

Avoid heat

Store in a cool place away from ovens, windows, or warm areas.

Keep away from moisture

Do not use a wet spoon and avoid humid environments.

Refrigerator guidance

Unopened matcha: Can be kept in the refrigerator to preserve freshness.

Opened matcha: If refrigerated, keep it in a fully sealed container and let it reach room temperature before opening to avoid condensation.

Approximate freshness timeline

• Unopened: 6–12 months
• After opening: best within 1–2 months for peak flavor and color

Signs your matcha is aging:

• Duller green or yellowish color
• Loss of fresh grassy aroma
• More bitterness
• Flat taste

Treat matcha like a fresh ingredient, not a pantry powder — seal it, protect it, and keep its vibrant character alive.
