Matcha is delicate. Its color, aroma and flavor can change when it is exposed to light, heat, humidity or oxygen. Storing it well helps every cup taste fresher and more balanced.
Keep it tightly closed
After each use, close the container properly. Contact with air can speed up oxidation and make matcha lose freshness. An airtight container is the best option.
Avoid direct light
Light can dull matcha's green color and affect its aroma. Store it in an opaque container or inside a cupboard, away from windows and direct sunlight.
Keep it away from heat
Do not store matcha near the oven, hob, coffee machine or any warm area. Heat can change its flavor and bring out more bitterness.
Protect it from humidity
Humidity can create clumps and damage the texture. Always use a dry spoon and avoid opening the tin near steam or hot water.
When to use it
Once opened, matcha is best enjoyed within the following weeks. It does not spoil immediately, but its brightest color, fresh aroma and smoothest flavor are strongest when it is fresh.
Conclusion
Storing matcha well is part of the ritual. A little care helps preserve its vibrant color, vegetal aroma and fine texture for your daily cup.
