Generally, Pu 'er tea cakes can be stored for more than 10 years, if the storage conditions are good or even longer. As Pu 'er tea belongs to post-fermentation tea, the active enzymes in it will change continuously during storage, and the taste will become more mellow with continuous fermentation.

Preservation methods of Pu 'er tea:

1, constant temperature: the storage temperature of Pu 'er tea is also exquisite, and of course it does not need to be changed deliberately, but the temperature of 20-30 degrees Celsius is the best. If the temperature is too high, Pu 'er tea may turn sour. You can put the tea in a cool place without the sun.

2, circulating wind: circulating wind can make tea faster, but be careful not to circulate too much, such as on the balcony, so that the taste of tea will be much lighter, just circulate moderately, don't put it in a place with heavy taste.

3、? Moderate humidity: Pu 'er tea can be placed in a relatively dry place, but a certain humidity is also essential. If it is too dry, it can be placed next to tea leaves to make the air more humid. Of course not too wet. Tea leaves that are too wet may become moldy and stale.
