How to Store Matcha Properly to Preserve Its Quality

Matcha is a very delicate ingredient. Even small changes in its environment can affect its flavor, color, and aroma.

By keeping the following four tips in mind, you can enjoy your matcha at its best for a longer time.

1. Protect from Oxidation

Matcha easily loses its flavor, aroma, and vibrant color when exposed to oxygen in the air.

To prevent this, store your matcha in an airtight container. A well-sealed container helps minimize oxidation and keeps your matcha fresh for longer.

2. Keep Away from Moisture

Matcha is highly sensitive to humidity. In damp environments, the powder can quickly clump, making it difficult to whisk properly.

Storing matcha in a moisture-proof container helps maintain its fine, silky texture.

3. Protect from Light

The vibrant green color of matcha comes from chlorophyll—a compound that is highly sensitive to light. Exposure to direct sunlight or even fluorescent light can cause the color to fade and affect the flavor.

Using a light-blocking container helps preserve both the appearance and taste of your matcha.

4. Prevent Absorption of Odors

Matcha easily absorbs surrounding smells, which can compromise its natural flavor.

Be especially cautious with plastic containers or zip-lock bags, as they tend to retain and transfer odors. A metal tin is ideal.

Storing Matcha in the Refrigerator: Be Careful of “Condensation”

While it's commonly believed that matcha should be kept in the refrigerator, one important thing to watch out for is condensation.
If you open a cold container straight from the fridge, moisture from the air can form on the inside, causing the matcha to absorb humidity and lose its quality. To avoid this, always let the container return to room temperature before opening it.
