I. Circulating air.　　Circulating air has more oxygen, which is conducive to the reproduction of some microorganisms in the tea, thus accelerating the change of tea.　　Therefore, there should be a moderate circulation of air, but not in the wind.　　In addition, pay attention to the surrounding environment do not have a bad smell, otherwise the tea will be tasteless. Can not be placed in the kitchen.　　Second, constant temperature.　　Normal indoor temperature, not too high or too low.　　Relatively speaking spring, summer and fall seasons Puerh tea will change faster than winter.　　It should not be exposed to the sun, and it is better to keep it in the shade.　　Third, moderate humidity.　　Nowadays, good Pu-erh tea is stored in a "dry warehouse", which means that it is stored in a dry environment, avoiding humidity.　　An environment that is too humid will lead to rapid changes in Pu-erh tea, but such changes are often "moldy", making the tea undrinkable.　　However, too dry an environment will slow down the aging of Puerh tea, so it is important to have a certain amount of humidity. I have a method: put a small cup of water next to the stored tea leaves to slightly increase the humidity in the air.　　How to save Pu-erh tea in the north Author: From: Life Encyclopedia Time:2005-11-8 I, the circulation of the air Simao City, Yunnan Province, Pu-erh Tea Culture Research Society, vice president of the He Shihua said that the circulation of the air there is more oxygen, is conducive to the tea in some of the microorganisms in the tea reproduction, and thus accelerate the change of the tea, but can not be Pu-erh tea hanging in the balcony, so that the placement of the tea, tea gas are blown, the tea flavor are blown away, drinking feel faint, and the tea will be a little bit of a little bit of a little bit of a little bit of a little bit of a lot of a lot of tea. Blow away, drink up feeling dull and tasteless. Therefore, there should be moderate circulation of air, but not put in the wind. In addition, we should pay attention to the surroundings do not have a bad smell, otherwise the tea will be tasteless. Therefore, it should not be placed in the kitchen or in other environments that have odors of life or industrial odors.　　Second, constant temperature Puerh tea placed in the temperature should not be too high or too low, the temperature should be based on the local environment, do not have to deliberately create the temperature artificially, the normal indoor temperature is good, it is best to keep between 20-30 degrees Celsius year-round, too high a temperature will make the tea accelerate fermentation and become acidic. Relatively speaking, spring, summer and fall seasons Pu'er tea will change faster than winter changes, no matter when, Pu'er tea must not be sunlight, in the shade is good.　　Third, moderate humidity "Nowadays, good Pu-erh tea is all about to be stored in a 'dry warehouse', 'dry warehouse' means to be stored in a dry environment, avoiding humidity." He Shihua said that too dry an environment will make the aging of Pu-erh tea become slow, so there should be a certain amount of humidity. In drier environments, a small cup of water can be placed next to the stored tea to slightly increase the humidity in the air. However, too much humidity will lead to rapid changes in Puerh tea, which is often called "mold", making the tea undrinkable. Humidity should be artificially controlled accordingly, the average annual humidity should not be higher than 75%, due to the warm oceanic climate along the coast, the humidity in the rainy season will be higher than 75%, so more attention should be paid to timely opening of windows to ventilate the air and disseminate water.
