Tea has a loose structure and contains a variety of "hydrophilic" substances, which are very hygroscopic, and the moisture content in tea exceeds 12%, which is easy to mold and deteriorate. Therefore, tea must be stored in a dry and ventilated place.
The aroma of tea is easy to volatilize, chlorophyll and tannin are easy to be oxidized. If the tea is stored for a long time, the fragrance will be reduced and the soup color will become dark or turbid. So when buying tea, buy less at a time and drink it as soon as possible.
If you buy tea packaged in paper or carton, move it into the bottle in time, and pay attention to sealing and avoiding light. Tea contains terpenoids, porous structure, easy to absorb peculiar smell, to be strictly isolated from peculiar smell items, especially with strong smell items, such as pepper, mothballs, soap, kerosene, wine, dried fish and other items.

Green tea is easy to absorb moisture and will deteriorate when the moisture reaches more than 5%. Green tea stored for a long time will lose its flavor even if it is not opened. Therefore, it should be drunk when fresh, and the storage period at room temperature is about one year. After opening, it should be poured into a closed container and drunk within one month.
Jasmine tea: It is a reprocessed tea of green tea with high water content and easy deterioration. Keep should pay attention to moisture, try to store in a cool and dry, no smell environment.

Tea bags packed in paper bags are about two years. If they are placed for more than three years, the fragrance will disappear and the original flavor will be lost.
Oolong tea: relative to green tea, aging deterioration slower, easier storage. Avoid light, high temperature and odor items, can be stored for a long time.
