The best way to store the tea is to place it in a spot avoiding direct contact with the sun, hot temperatures, humidity, and strong smells. Room temperature is fine.
For best results, in between uses roll up the bag holding the tea, clip it closed, and store it on its own or in its can.
For matcha cans, if you are a frequent matcha drinker (roughly, someone who usually finishes their matcha can within 2 weeks), you can pour the powder from the bag into the can for convenience. Otherwise, we recommend rolling the bag shut and storing it inside the can.
