Can storage method: Using iron cans to store tea is simple and convenient, and you can drink it at will. It is the most popular and commonly used method for storing tea at home. Just put the tea leaves you bought into a clean iron can. If it is a newly bought iron can, or an iron can that has been used to store other foods, you can first put a small amount of tea leaves in it, then cover it and store it for a few days to absorb the odor. Scrubbing the iron can with tea leaves can also remove the odor. The iron can containing tea leaves should be placed in a cool place, not in direct sunlight or in a humid or heat-sourced place. This can prevent the iron can from oxidation and rusting, and can also inhibit the aging and deterioration of the tea leaves in the can.
