Thirdly, plastic bags should be strong and thick. Fourth, plastic bags should be free of holes and smells.

3. Pot storage method, the most popular and commonly used tea storage method at home at present, as long as the bought black tea leaves are put into clean tin cans. If it's a new tin can or a tin can where other foods have been spared, you can put a small amount of tea powder in it first, then cover it and store it for a few days so that the odor can be completely absorbed. At the same time, scrubbing tin cans with tea powder can also remove odor. Tea cans should be placed in a cool place, not in direct sunlight or in a humid place with a heat source, which can not only prevent the tin cans from oxidation and rust, but also inhibit the aging and deterioration of tea in the tin cans, killing two birds with one stone.
