Pu'er tea is very popular with tea friends. The characteristic of Pu'er tea is that the longer the tea is stored, the more fragrant the tea itself will be. Despite the merciless time, Pu'er has been fragrant for a long time. So when it comes to the shelf life of Pu'er tea, as long as you keep Pu'er tea in the right way, its shelf life is very long.
The unique quality and aged fragrance of Pu'er tea are formed by fermentation during storage. After a certain period of time, the main chemical components of raw Pu'er tea, such as tea polyphenols, amino acids, sugars and other substances, change between each other, making the soup color and fragrance tend to be idealized. However, if the storage conditions are improper or do not speak of scientific indefinite storage, it will inevitably reduce its quality. If the quality of Pu'er tea reaches the highest level, it will be stored blindly for an indefinite period, which will inevitably make the beneficial components in the tea gradually decompose and oxidize, and then lose the special flavor of Pu'er tea. Therefore, the storage process of Pu'er tea should be determined according to the situation. Generally, the new raw tea can be stored for about 10 years, and then the quality can be satisfied. However, it doesn't need several decades for the fermented tea. Generally, the quality and flavor of the tea can be improved after 2-3 years storage.
Tea has a shelf life, but it is related to the variety of tea, and the shelf life of different tea is also different. For example, Yunnan Pu'er tea and ethnic brick tea are better aged, with a shelf life of 10 to 20 years. Another example is Wuyi rock tea, which is aged every other year, but has a rich fragrance and mellow taste; black tea in Hunan, Fu brick tea in Hubei, Liubao tea in Guangxi, etc. will not deteriorate or even improve the quality of tea as long as stored properly. Ordinary tea is better fresh. For example, green tea has a shelf life of about one year at room temperature. However, the main factors affecting the quality of tea are temperature, light and humidity. If the storage method is proper, and these factors are reduced or eliminated, the tea can be kept for a long time.
To judge whether the tea is expired, there are mainly the following aspects: to see whether it is moldy or stale; whether the green tea is red and the soup is brown and dark; the concentration, convergence and freshness of the taste are reduced; in addition, to see the shelf life on its packaging; in addition, if it is bulk tea, it is better not to drink for more than 18 months. After the expiration of the tea can be put into a flowerpot when the nutrition of flowers. Can also be dried to make pillows, instead of buckwheat, tea pillow is good for sleep.
