High-grade Yunnan red, where the tea soup and the teacup are in contact, often show a golden circle, and the creamy turbidity will appear immediately after cooling (the tea soup will appear light brown or orange milky turbidity after cooling, which is one of the symbols of high-quality black tea).

Keep in a tightly sealed tin can

　　Tea products are very easy to absorb peculiar smell and get damp. If Dian black tea is damp, not only will the tea quality overflow in large quantities and affect the drinking experience, but it will also become moldy and deteriorate and lose its drinking value. Therefore, when preserving Yunnan black tea, a container with better airtightness should be selected, such as an iron can. Iron cans are available everywhere and are affordable, but iron cans also need to be selected. First, they are clean and odorless, and secondly, they have better sealing properties.
　　Packed in iron cans can not only prevent the tea taste from odor, and better retain the aroma of Yunnan black tea; it can also put the opened tea products back into the tin can for storage.

　　 Note: For the opened tea, first roll the bag inside the opening twice, clamp the opening with a convenient clip, and then put it into the tin can. Keep tin cans away from the kitchen or bathroom where there is no peculiar smell.

Keep in a clean ceramic jar

　　 When choosing a clean, well-sealed ceramic pot to store Yunnan black tea, you need to pack the tea in a sealed bag first, and then put it in the ceramic pot. Dian black tea is roasted at a high temperature and its aroma has been fully stimulated. After contact with air, it is easily oxidized, and the aroma is lost with the air.

　　Dian black tea that has been placed in the air for a long time, the aroma will gradually fade, which will affect the taste of drinking. This is why the best drinking period of Yunnan black tea is usually only about three years. It is not like Pu'er tea that can be stored for a long time in time and transform itself.

　　 Note: Do not use ceramic pots that are cracked, or have been filled with other pots that have a strong smell and are not exhausted, to store tea products. The place should be kept away from humidity and peculiar smell.

Store in a sealed bag and refrigerator fresh-keeping layer

The tea can be packed in a waterproof and airtight bag and placed on the fresh-keeping layer of the refrigerator. Take it out when drinking, and seal it back when not drinking it in the fresh-keeping layer of the refrigerator.

　　 Note: When storing Yunnan black tea in the refrigerator, the sealed bag must be sealed, and the sealed bag must not be damaged, otherwise the tea will not only get damp, but also absorb the peculiar smell in the refrigerator.
