Matcha is a natural product – it contains no preservatives or artificial additives. This means that over time, it may lose its properties, flavor, and intense green color. But does this mean it goes bad?

The answer is yes, but not in the traditional way . Matcha won't go moldy like bread or sour like milk, but it will age —and that's when it's worth knowing when its quality is no longer at its best.

How long can you store matcha?

• Unopened matcha stays fresh for approximately 6–12 months from the production date (check the date on the packaging).

• After opening, it is best to use it within 30–60 days , especially if you care about the intense taste, smell and nutritional value.

How do you know if matcha is old?

Here are some signs that your matcha may have lost its freshness:

• Color: instead of intense, bright green, it is matte, yellow-green or olive.

• Smell: weaker, less fresh, slightly "papery".

• Taste: more bitter, tart, without the sweet note of umami.

• Consistency: less loose, slightly moist or lumpy.

Can you drink expired matcha?

If matcha has been stored well (in an airtight container, away from light and moisture), it will not harm your health – but it will not be as tasty or nutritious.

In case of major changes in color, smell or taste, it is better to replace it.

How to store matcha to keep it fresh longer?

• Store in an airtight, opaque container.

• Keep in a cool, dry place

• Avoid exposure to light and air

• You can keep it in the fridge (tightly closed)

Summary

Matcha has an expiration date – it doesn't spoil like food, but over time it loses its best qualities: freshness, flavor, color, and health benefits. If your matcha seems faded, bitter, or flavorless, it's time for a new batch.

Well-stored matcha = better taste, more energy and daily pleasure.
