Matcha green tea is very sensitive to heat, humidity, and light.
You must be careful with how you store your Matcha since it loses its color and quality very quickly when exposed to any of the above elements.
Our Matcha is safe in its airtight bag or tin before it is opened and protected except against heat. Therefore, it is recommended to keep your matcha tea refrigerated. Once the tin is opened, it should be consumed within 1-2 months. After opening your matcha, please close the lid or bag tight after each use and keep it in a refrigerator. If you move it to a different container, avoid glass jars that would let the light in. Please note that if you do not seal your matcha container, the flavor may be influenced by what you have in your fridge!
If Matcha has to be kept for a long time, it may be stored in a freezer. To prevent frozen Matcha from becoming wet when exposed to air it should be thawed up to room temperature before the package is opened. The same for your refrigerated matcha. Ideally, it should be returned to room temperature before being opened for use.
