Tea is one of the most favorite drinks in the daily life of many people. Some people love to drink new tea, while others love to drink Chen tea. So, does the tea have a shelf life? What is the shelf life of tea? Here to answer everyone: tea has a shelf life, but related to the variety of tea, the shelf life of different tea is not the same. Like Pu'er tea in Yunnan, brick tea of ​​ethnic minorities, Chenhua is better, with a shelf life of 10 to 20 years. Another example is Wuyi Rock Tea. In the next year, Chencha is rich in aroma and rich in flavor ; black tea in Hunan, brick tea in Hubei, Liubao tea in Guangxi, etc., as long as they are properly stored, will not only deteriorate, but even improve the quality of tea. The country has established tea standards based on food hygiene standards, and has also defined the shelf life. However, it is worth noting that the state does not set standards for Pu'er tea because it is a fully fermented product and it is more difficult to set a shelf life standard. Other types of tea should be operated in strict accordance with national standards. Otherwise, after the shelf life, the tea will lose its own quality and charm. If it is wet, it will be harmful to the human body. The average tea is still fresher. Such as green tea, the shelf life is usually 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 appropriate to reduce or eliminate these factors, the tea can be preserved for a long time. The more fresh the tea, the better. In fact, it mainly refers to green tea. Because green tea is difficult to keep fresh in the past, often after the summer, the tea will slowly turn yellow and the taste will be relatively poor. Nowadays, the fresh-keeping technology of tea has been relatively advanced. In particular, some large tea houses often have fresh-keeping conditions such as cold storage, which can improve the fresh-keeping period of new tea. Therefore, it is better to buy with the drink, but to ensure " freshness " . For those teas that are now being sold, the suggestion here is not to buy. Because usually after the tea is fried, it has to undergo post-processing, such as the high-end " Longjing " . In the frying process, it is generally divided into two processes: " green pot " and " hot pot " . " Green pot " has the effect of killing, but The tea that is fried in the " green pot " will have moisture, so it is necessary to " energy pot " , wrap the tea, put white ash to absorb the water inside, generally it should be sealed for about a week, and the tea after the ash is soaked. It is delicious and can be stored for one year at a constant temperature. There is no such effect on the scene. Moreover, the shopping malls are crowded and the tea hygiene on the spot may not be able to keep up. The identification of new tea and Chen tea is mainly to see its color, fragrance and taste. Color refers to the role of tea in the process of storage, by the role of oxygen and light in the air, green tea gradually faded from the verdure green of new tea. Black tea is turned into grayish brown from the black tea of ​​the new tea. In terms of taste, the new tea is fresh and refreshing. The taste of Chencha is light and bitter, slightly bitter, and the aroma is also turbid by the fragrance. However, this difference is specific to each tea, and if the storage conditions are good, the difference will be relatively small. Judging whether the tea is out of date, there are mainly the following aspects: see if it is moldy, or smelling ; whether green tea is red, the color of the soup is brown and dark ; the concentration, astringency and freshness of the taste are decreased, in addition to seeing it The shelf life on the package, and if it is bulk tea, it is best not to drink more than 18 months. The above is a related introduction about the shelf life of tea.
