We all know the vibrant green is everything when it comes to matcha. But the moment you store it wrong, oxidation kicks in, and just like that, your vibrant green turns dull.

Think of matcha like fresh produce: the way you store it affects its flavor and benefits. If you've ever opened a tin only to find dull, flavorless powder, you're not alone. Proper storage makes all the difference in preserving your matcha’s vibrant color, fresh taste, and nutritional value.

Why Matcha Goes Stale

Matcha is finely ground green tea powder, and it's more sensitive to air, light, heat, and moisture than regular tea leaves. Exposure to these elements causes oxidation, leading to a loss in flavor, color, and aroma. That’s why your matcha may start looking yellowish or tasting bitter over time.

How to Store Matcha Correctly

Keep it airtight: Always store matcha in an airtight container to minimize oxygen exposure.
Avoid sunlight: Store your tin in a cool, dark cabinet — not by the stove or a sunny window.
Keep it dry: Matcha absorbs moisture easily. Never scoop with a wet spoon.
Refrigeration optional: If you live in a hot climate or don’t use matcha often, storing it in the fridge (inside an airtight container) can help — just make sure to bring it to room temp before opening.

How Long Does Matcha Last?

Unopened, high-quality matcha can stay fresh for up to a year. Once opened, it's best to use it within 1 month for ceremonial grade and 1–2 months for culinary grade. The fresher, the better!
