Why is Pu 'er tea packed in paper?

Compared with the sealing requirements of other teas, Pu 'er tea does not need to be isolated from the air. On the contrary, a certain amount of contact with air can promote the late transformation of Pu 'er tea. Therefore, the cotton paper with strong air permeability can meet the requirements of Pu 'er tea, without direct contact with air in a large area, and can also reach the state of unsealing, which can be said to be the best choice for Pu 'er tea packaging.

2, can absorb odor

Tea is very absorbent and particularly sensitive to miscellaneous tastes. It tastes bad if you are not careful. At this time, a good piece of tea is wasted. Cotton paper has a good smell absorption function, which can isolate odor to a certain extent and keep the inside of tea cake clean.

3, it is beneficial to long-term preservation

Unlike other teas, Pu 'er tea may go bad if you don't drink it for a while. On the contrary, Pu 'er tea has the characteristics of getting more fragrant with age. Many people will keep it for a period of time after buying it, and some collectors will even keep a cake of tea for several years or even more than ten years.

At this time, metal cans and the like are not suitable. But cotton paper has the characteristics of long-term durability. Only when properly preserved, cotton paper can preserve tea well, even for three to five years.

Paper has no peculiar smell, good air permeability, can absorb moisture in the air, but it is also easy to dry, which is very suitable for Pu 'er tea packaging. Bamboo shoot shells used in the early days are also breathable, but if they are difficult to dry after soaking in water, it is not conducive to the storage of Pu 'er. Vacuum plastic packaging will definitely kill the activity of Pu 'er tea, resulting in Pu 'er tea not aging and becoming "dead tea".

Extended data:

The preservation of Pu 'er tea also needs to pay attention to the following factors:

1, temperature

The temperature of Pu 'er tea storage environment is between 20-30℃. Too high or too low temperature is not conducive to the aging of Pu 'er tea. At the same time, air conditioning and internal light should be avoided to change the tea quality of Pu 'er.

2. Humidity

The relative humidity is kept between 65% and 75%. Too high or too low humidity is not conducive to the aging of Pu 'er tea. When the climate is dry, Pu 'er tea (especially raw tea) will enter a dormant state, which is not conducive to aging. You can use a humidifier to increase the air humidity properly or often wipe the floor with a wet towel, which can not only humidify but also clean the floor.

Pay attention to proper humidity maintenance in dry rooms. You can buy thermometers in some home squares, and you will have a good grasp of humidity changes. In very hot and humid places, tea leaves come into contact with a lot of water, which will lead to rapid aging and deterioration of tea leaves and easy mildew, so pay attention to ventilation and drainage.

3. Ventilation equipment

Pu 'er tea also needs "breathing", and its transformation needs oxygen and moisture. If you store Pu 'er tea at home, you must put it in a dry and ventilated place, because the oxygen content in the circulating air is conducive to the reproduction of microorganisms in tea.

Conducive to the transformation of the contents of Pu 'er tea and accelerate the aging of Pu 'er tea. Under the dual effects of enzymatic and non-enzymatic oxidation reactions, the benign aging of Pu 'er tea can be promoted and accelerated.

However, it should be noted that Pu 'er tea cannot be directly blown by the wind, nor can it be hung on the balcony, so that the Pu 'er tea placed in this way will be blown away, the tea taste will be blown away, and it will feel dull and tasteless to drink. Therefore, the storage of Pu 'er tea should have moderate air circulation, but it should not be placed in the air outlet. Although the transformation is slow, it can maintain the authenticity of Pu 'er tea.

4. Cool

The so-called "cool" means to put Pu 'er tea in a place where it is not exposed to the sun, to minimize the influence of strong light on Pu 'er tea, and not to put Pu 'er tea in a high temperature environment for a long time, especially in the climate of high temperature and high humidity in the south.

High temperature not only makes Pu 'er tea lose its activity, but also is not conducive to the aging of Pu 'er tea itself. Over time, Pu 'er tea will "die out", that is, it has no value of storage and transformation.
