To preserve the quality and taste, tea requires special storage and matcha is no exception given it can be vulnerable to changes in the environment such as light, humidity, odor and temperature. Particularly, matcha can be affected by high temperature and humidity levels. If not stored properly the unique scent from matcha, often referred to as Ōiga, can become distorted. The deep green color of the matcha may also redden due to oxidation.

How To Properly Store Matcha

Matcha needs to be sealed and stored away from high temperatures. The best places to store it are in the refrigerator, freezer or in a cool dark place. Lower temperatures help maintain to quality of the matcha. Un-opened matcha is best stored in the freezer, once you take it out from the freezer or refrigerator it is important for it to adjust to room temperature. Once it adjusts to room temperature it is recommended that you drink it as soon as possible in order for the matcha quality not to deteriorate. After use, make sure you tightly seal the pack or container and store it back in the refrigerator or in a cool dark place.

Precautions

Clumping

Matcha is a fine green tea powder that can measure anywhere between 5-10 microns and may clump due to static electricity and pressure of its own weight during storage.  If you come across clumps in your matcha it is recommended that you use a fine sieve or strainer to sift the powder. Be careful of handling the matcha with wet hands or utensils, as the faintest drop of moisture or water can cause the matcha in your container to form hard lumps that cannot be broken down or sifted.

Fading (Due to light)

The unique green color of matcha can fade to due light exposure. It is recommended that you seal the matcha in a UV shielding container/package and store it in a dark place.
