Dark tea is also a type of tea that can be stored for a long time. Some people like to wrap black tea in bamboo shells,

but they should be aware that bamboo shells are prone to moths. You can use odorless kraft paper, rice paper, etc.

to wrap the tea, put it in a clay pot, and seal it well. Make sure the jars are placed high and not too close to the floor or ceiling to prevent insects and moisture.
