Matcha is an exceptional Japanese green tea, renowned for its rich aroma, intense green colour, and numerous health benefits. If you’d like to learn more about its origins, production, and properties, check out our comprehensive guide to matcha below. However, its delicate nature also makes it particularly sensitive to its environment: air, light, heat, and humidity.

Our tins are designed to preserve your matcha

Proper storage of matcha is essential to preserve:

• its delicate, plant-based aromas,
• its bright green colour,
• its nutritional properties,
• its delicate texture and rich flavour.

Learn how to store your matcha properly and avoid the most common mistakes.

Why is matcha such a delicate tea?

Unlike teas that are brewed from leaves, matcha is an ultra-fine powder obtained by grinding green tea leaves. This texture significantly increases its surface area in contact with the air and exposes it more to external factors such as air, light, heat, and humidity. These factors naturally accelerate its oxidation and can affect its quality.

A delicate powder

Unlike a whole tea leaf, matcha powder has a much larger surface area exposed to air, light, and moisture, which naturally accelerates its oxidation if it is not properly protected.

Matcha that is not stored properly can quickly lose its vibrant green colour, become more bitter, lose its aroma, and eventually see its nutritional value decline. Proper storage of matcha therefore plays a key role in its taste.

Common mistakes to avoid

The main mistakes to avoid are leaving matcha in a non-airtight package or a container that isn’t sealed properly, which allows air and moisture to enter and accelerates the oxidation of the matcha. You should also avoid exposing it to light or heat, as direct light and high temperatures degrade the tea’s natural pigments and aromas.

Another mistake would be to store it in the refrigerator without proper protection. This is because temperature changes in the refrigerator can cause condensation, and this moisture can damage the powder and cause the matcha to clump.

You should avoid frequent temperature fluctuations as much as possible. Temperature fluctuations make the product more fragile and accelerate its deterioration.

The best way to store matcha

An airtight, opaque container

The key to proper storage lies first and foremost in the container. Matcha must be protected from air and light.

Our tins were specially designed with this in mind:

• 100% Japanese technology, widely recognized and difficult to replicate.
• Printed directly onto the metal, without a label, for greater durability.
• Airtight seal that minimizes oxidation.

Why is metal ideal for matcha?

Metal—and stainless steel in particular—is widely used in Japan throughout the matcha production chain: the storage of leaves and powder, as well as handling and transportation. This material also ensures compliance with the strictest hygiene standards.

In fact, this material is rust-resistant, neutral, has no effect on the taste or properties of the tea, is durable, and provides protection. It ensures optimal preservation without altering the product.

Should you store matcha in the refrigerator?

Contrary to popular belief, high-quality matcha packaged in an airtight tin does not need to be stored in the refrigerator.

Our tins are designed to:

• Store them simply in a cupboard at room temperature.
• Effectively protect against air, light, and moisture.
• Avoid risks associated with temperature fluctuations and condensation.

A dry environment with a stable room temperature is ideal.

How long can matcha be stored?

For best results, we recommend consuming the matcha shortly after opening.

Choosing the Right Matcha for Better Storage

The quality of the packaging plays a key role. To preserve your matcha:

• Choose airtight, opaque containers.
• Avoid bags that don't provide much protection.
• Choose sizes that suit your needs.

Our Japanese tins are designed to offer convenience, hygiene, and optimal freshness, right in your home.

How can you tell if matcha has been stored improperly?

There are several signs that may indicate a loss of freshness, such as a more yellow or dull colour, a less vegetal aroma, a more pronounced bitterness, or a coarser or clumpy texture.

These changes are generally caused by excessive exposure to air, light, or moisture.
