We recently received a question from one of our customers on how to store matcha.
Unopened matcha should be stored in a cool place with no direct sunlight, and for opened matcha, it is best to use an airtight container.
If you live in a place with a hot or humid atmosphere, store the matcha in the fridge.
We suggest putting the whole tin or package in a plastic ziplock bag (with minimal air inside)
and store it in the fridge.
Be sure to let it return to room temperature before opening the container. This is because of condensation–moisture from warmer air would damage the tea inside.
We recommend using matcha within two months after opening.
