How should I store the matcha powder?

Hello from Maru Take Ebisu in Japan!

Have you noticed how extreme the summers have become lately? In Japan, the scorching heat has become a regular occurrence, and I have to tell you:this heat is the #1 enemy of your Matcha.

In the past, people said, "If it's unopened, storing it in a cool, dark place at room temperature is fine." But with today’s rising temperatures, that is no longer safe. Even inside an unopened tin, Matcha slowly deteriorates if left in a room over 30°C (86°F). You might open it only to find the vibrant green has turned a dull, disappointing color.

Even in winter, is your Matcha sitting near a stove or in a heated room above 20°C (68°F)? Today, I’ll share the "Pro-Recommended Modern Storage Manual" adapted to our changing climate.

The Verdict: The Fridge is the Only Place for Your Matcha

What about the Freezer?

Beware of the "Condensation" Trap!

Before you rush to the fridge, there is one golden rule you must never break:Never open the lid immediately after taking it out of the fridge.

Just like eyeglasses fog up when you enter a warm room, water droplets (condensation) will instantly form on the cold tin. If this happens inside the tin, the Matcha absorbs the moisture, clumps up, oxidizes, and the aroma dies...

In Uji, master tea blenders store the raw tea leaves (Tencha) in massive, temperature-controlled refrigeration units. They only grind the leaves into powder using stone mills right before an order is shipped. Even the grinding rooms are strictly temperature-regulated to prevent heat damage.

The "Pro Tip": Use Small Portions

If waiting every time is too much trouble, try the "Portioning Technique":

• Transfer about one week's worth of Matcha into a small tin. You can keep this in a cool spot in your kitchen at room temperature for quick use.
• Keep the rest of the main supply sealed tightly in the back of the fridge.
• Note: One bowl of Usucha or a Matcha Latte uses about 1.5g to 2g. If you drink one cup a day, move about 14g to your small tin.

Summary: Great Matcha Requires Temperature Control

• Modern summers (and heated kitchens) are too hot for Matcha.
• The Fridge is a must, even for unopened tins.
• The Freezer is for long-term storage or cooking grade.
• Always let it reach room temperature before opening.

At Maru Take Ebisu, we ship our Matcha in light-shielded, airtight tins or aluminum packs. You can simply re-seal them and pop them in the fridge!

One Last Thing: Choose Your Shop Wisely

Even if your storage at home is perfect, it means nothing if the shop’s storage was poor. Think of Matcha like fresh spinach or greens ? it's a leaf. Many giant online marketplaces store products in massive warehouses that get incredibly hot in the summer. Can quality be maintained in that environment? Likely not.

"But wait, doesn't Maru Take Ebisu sell on Amazon?" Yes, we do! However, we do not use Amazon’s warehouses.Every single order is shipped directly from our own temperature-controlled facility. We never let our tea sit in a hot, third-party warehouse.

We want you to enjoy the true, vibrant taste of Kyoto Matcha down to the very last scoop.

A Final Word to Matcha Lovers and Shop Owners

If there are matcha latte shops in your country, I truly pray that they store their matcha safely in the refrigerator after closing.

From my professional perspective, it is simply unthinkable to leave matcha sitting on a counter overnight in a shop where temperatures might exceed 30°C (86°F). If a shop manages their precious tea that way, their quality control is nonexistent. At ; Maru Take Ebisu , we consider such neglect a "sin" against the hard work of the tea masters in Uji.
