1, plastic bag, aluminum foil bag storage method

It is best to choose a plastic bag that has a seal and is used for food. The material is thicker and denser. Do not use smelly or remanufactured plastic bags. The air in the bag should be squeezed out as much as possible after putting it into the tea bag. The principle of packaging tea in aluminum foil bags is similar to that of plastic bags. In addition, the purchased tea is packaged in bags, sealed and placed in the refrigerator, and then brewed in batches, so as to reduce the chance of the tea coming into contact with the air after opening, and delay the occurrence of quality deterioration.

You can choose tin cans, stainless steel cans or tin cans with a dense texture. If it is a newly purchased jar, or a jar that has stored other items in the past, you can put a little tea powder in the jar first, cover the lid, and move it up and down, left and right.

The metal cans containing tea should be placed in a cool place, not in a place with direct sunlight, peculiar smell, humidity, or heat source. In this way, the iron can is not easy to rust, and it can also slow down the aging and deterioration of the tea.
