At present, there are many varieties of Pu 'er tea in the market, and there are also many manufacturers, tea shops and tea shops that produce Pu 'er tea. Besides Simao and Xishuangbanna in southern Yunnan, other cities and states are also producing Pu 'er tea. Different producing areas, varieties, processing techniques and storage methods make the quality of Pu 'er tea vary greatly. Pu 'er tea can be divided into raw and cooked tea, loose tea and pressed tea. Therefore, how to choose and collect Pu 'er tea is particularly important. 1. Selection of origin: Pu 'er tea originated in the dense forests on both sides of Lincang, and its historical origin is in the ancient six tea mountains in Xishuangbanna. The quality of Pu 'er tea produced in Simao, Xishuangbanna, Lincang and other cities and counties in Yunnan is good. As far as the origin is concerned, the six ancient tea mountains in Xishuangbanna, Nannuo Mountain in Menghai, Bulang Mountain, Hekaishan Mountain and Banzhang Mountain, Jingmai Mountain in Lincang, Xiaojinggu in Jinggu, Mengku, Lincang, Zhenkang Maanshan and Yongde in Shuangjiang County, Lincang City have excellent quality and are good raw materials for processing Pu 'er tea. Generally speaking, Pu 'er tea produced in these places is of good quality. 2. Choose Pu 'er tea with high-quality tea production bases and excellent varieties of tea balls: Yunnan Tea Institute, Yunnan Longsheng Group and Simao Tea Seed Farm, all of which have large areas of high-quality tea production bases and excellent tea varieties. 4. Choose enterprises with commercial integrity to buy: enterprises with commercial integrity generally have business licenses, health permits, tax registration certificates and clearly marked prices. The employees of the enterprise have received professional training, and have rich basic knowledge of tea and good professional ethics. There are signs such as company name, trademark, bar code and net content on the package, which will not mislead consumers. 5. Choose a well-known brand: The well-known Pu 'er tea brand in Yunnan has a Chinese tea brand. "China Tea Brand" is the trademark of China Tea Company. After 1991, Yunnan stopped using the trademark "Chinese Tea Brand". Moreover, since 1991, "Yunnan Tea Branch of China Native Animal Products Import Company" has been renamed as "Yunnan Tea Import and Export Company of China Origin Animal Products". However, at present, there are still many tea shops selling Qizi cake tea and brick tea with the words "Yunnan Tea Branch of China Native Products and Animal Products Import Company" and the trademark "China Tea Brand". Except for a small amount of old Pu 'er tea before 1991, most of these teas are counterfeit, so consumers should be reminded. At present, the well-known Pu 'er tea in Yunnan includes: Jixing brand of Yunnan Tea Import and Export Corporation, a native product and livestock company in China; Dayi brand of Menghai Tea Factory; Songhe brand and Baoyan brand of Xiaguan Tea Factory; Longsheng brand of Yunnan Longsheng Group; Puxiu brand of Pu 'er tea group; and six Chashan brands of Yunnan six Chashan tea companies. 6. Evaluate the appearance and quality of tea: When purchasing Pu 'er tea, we must carefully evaluate the quality of tea. For loose Pu 'er tea, we mainly look at four factors: cord, color, crushing and cleanliness. Pressing Pu 'er tea mainly depends on whether the cake shape and brick shape are even, whether the edges and corners are neat, whether the mold lines are clear, whether the layers are not falling off, whether the sprinkling surface is even and whether the tightness is moderate. Re-weigh whether it is sufficient. On the basis of looking at the appearance, it is necessary to open the soup to evaluate whether the aroma is normal and the soup color is good. Also weigh whether the price is suitable. The older Pu 'er tea is, the more fragrant it is, which makes Pu 'er tea have great collection value. Some collectors have calculated that Pu 'er tea preserved five years ago will appreciate by 3% every year. After 6-1 years, its value will double every year, and after 1 years, it will be worth several times. Tea over 3 years can be expressed by "sky-high price". Generally, good raw cakes should be stored for ten years, while good cooked cakes should also be stored for four or five years. Every year, a large amount of raw tea needs to be collected and aged to become aged Pu 'er tea. When the color and fragrance of the collected Pu 'er tea reach the best level, there is no need to store it any more. To collect Pu 'er tea, you must collect valuable Pu 'er tea. For example, Pu 'er tea, several famous brands of Pu 'er tea, various commemorative cakes and bricks. Pu 'er tea is generally collected by pressing Pu 'er tea, which is easy to collect because of its small size and small area. It is better to collect raw cakes, bricks, melons and melons in the collection of Pu 'er tea. Pu 'er tea, a handicraft, is mainly for viewing and has little collection value. Among the raw teas, the wild ancient teas from several ancient tea mountains are better. The wild ancient tea mentioned here mainly refers to the cultivated ancient tea that has been abandoned for many years and grown in the virgin forest, rather than the pure wild tea that has not been domesticated. 2. The collection environment should be kept away from direct sunlight, clean and ventilated, and there is no smell. If the storage quantity is large, a special warehouse can be set up for storage; If the quantity is small, individuals can store it at home, and ceramic crocks can be used for storage. Unpack all kinds of bamboo shoots from Pu 'er loose tea and pressed tea, put them directly in the jar and seal the jar mouth.
