If the quality of a tea product is not up to standard at first, or it is improperly stored in the later period, then the quality of the tea product will not be good no matter how long it is kept, and some unscrupulous vendors in the Pu 'er tea market will make a lot of fakes.
The main means of counterfeiting is to accelerate the aging of raw tea through wet storage, make so-called "aged old tea" or make the packaging of tea obsolete to show the sense of obsolescence. It is difficult for ordinary consumers to identify the authenticity and pros and cons of aged Pu 'er tea.
Storage mode
1, which must be dried and aged. Dry warehouse will not be moldy and slow to transform, but it can keep the authenticity of Pu 'er tea. Dry storage refers to the storage of tea leaves after fermentation in an environment with moderate temperature and humidity and good ventilation; Wet warehouse means that tea merchants put tea leaves in an environment with poor ventilation and high humidity to accelerate aging and sell old tea at a high price in the market for profit.
The temperature should not change suddenly. If the temperature in the warehouse is too high and the temperature difference changes too suddenly, it will affect the liveliness of the water-based tea soup.
3. Avoid odor infection. Tea is the best way to absorb odor. Sprinkling a handful of dry tea leaves will remove the odor in the air, and efforts should be made to keep the storage environment clean and odorless.
4. Avoid the sun and wind. In the sun, phenols and chlorophyll are more easily oxidized, which makes tea discolored and deteriorated. The increase in temperature will also accelerate the fermentation of tea and make it sour. In the air, there is more oxygen in the circulating air, which is beneficial to the reproduction of microorganisms in tea, thus accelerating the changes of tea. But tea can't be hung in the air outlet, otherwise the tea will be blown away, the tea taste will be blown away, and it will be indifferent and tasteless to drink.
5. Pack with bamboo poles. This traditional packaging material and method can help Pu 'er tea to filter off the odor in the post-fermentation process, thus ensuring its purity.
6. Pay attention to tea age life. The age life of Pu 'er tea is 60 years, or 100 years, or hundreds of years. Without conclusive data, the aging degree of Pu 'er tea is often judged only by the intuition of tea tasters. For example, Fuyuan Chang and Tongqing Lao Pu 'er round tea have reached the highest point of aging, and must be sealed and preserved to avoid continuous rapid post-fermentation, resulting in the gradual disappearance of tea properties and poor taste. The Jinguagong tea in the Forbidden City has been aged for one or two hundred years, and its taste is: "The soup color is old and the tea taste is weak."
7. The humidity should not be too high or too dry. Too high humidity is easy to make tea go bad and moldy; If it is too dry, the transformation of tea will be too slow.
