How should I store matcha?Updated a year ago

Once the package is opened, we strongly recommend that you use it up as soon as possible. An opened package of matcha will keep ideal freshness for about 6 months. We also recommend storing it in a cool dry place, away from moisture, sunlight and odors. If you would like to keep your matcha fresh for a longer time, we recommend that you store an unopened package in the refrigerator. If you would like to store it long-term (beyond 6 months), we recommend storing it in the freezer.
