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. In addition to Simao and Xishuangbanna in southern Yunnan, Pu 'er tea is also produced in Lincang, Dali, Baoshan, Dehong, Kunming and Honghe. Different producing areas, different varieties, different processing techniques and different storage methods make the quality of Pu 'er tea vary widely. Pu 'er tea can be divided into raw tea and cooked tea, loose tea and pressed tea. Therefore, how to select and collect Pu 'er tea is particularly important. 1. Origin selection: Pu 'er tea originated in the dense forests on both sides of Lincang, and its historical origin is Guliucha Mountain in Xishuangbanna. Pu 'er tea produced in Simao, Xishuangbanna, Lincang and other cities and counties in Yunnan is of good quality. As far as the origin is concerned, the six ancient tea mountains in Xishuangbanna, Nannuo Mountain, Brown Mountain, Hekaishan Mountain and Banzhang Mountain in Menghai, Jingmai Mountain in Lincang, Xiaojinggu in Jinggu, Mengku, Lincang, Zhenkang Maanshan and Yongde in Shuangjiang County of Lincang City are good raw materials for processing Pu 'er tea. Generally speaking, the quality of Pu 'er tea produced in these places is very good. 2. Choose Pu 'er tea with high-quality tea production bases and excellent varieties of tea balls: Yunnan Academy of Tea Sciences, Yunnan Longsheng Group and Simao Tea Farm, all of which have large-scale 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. After professional training, the employees of the enterprise 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 famous brands: The famous Pu 'er tea brands in Yunnan include China Tea brand. "China Tea Brand" is the trademark of China Tea Company. 199 1 year later, Yunnan has stopped using the trademark "China Tea Brand". Moreover, after 199 1 year, "China Native Animal Products Import Company Yunnan Tea Branch" has been renamed as "China Native Animal Products Yunnan Tea Import and Export Company". However, 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". Most of these teas, except a small amount of old Pu 'er tea 199 1 years ago, are counterfeit, so consumers should be reminded. At present, the well-known Pu 'er tea in Yunnan is: Jixing brand of Yunnan Tea Import and Export Company, 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 Liuchashan Tea Company. 6. Evaluate the appearance and quality of tea: When purchasing Pu 'er tea, you must carefully evaluate the quality of tea. For loose tea, we mainly look at four factors: rope, color, crushing and cleanliness. Pressing Pu 'er tea mainly depends on whether the cake shape and brick shape are uniform, whether the edges and corners are neat, whether the mold lines are clear, whether the layers do not fall off, whether the sprinkling surface is uniform and whether the tightness is moderate. Re-weigh whether it is enough. 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 appropriate. 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 30% every year. It will double every year after 6~ 10 years, and several times after 10 years. Tea preserved for more than 30 years can be expressed by "sky-high price". Generally, good raw cakes should be stored for ten years, and good cooked cakes should 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 collected Pu 'er tea reaches the best color and fragrance, there is no need to store it again. To collect Pu 'er tea, you must collect valuable Pu 'er tea. For example, Pu 'er tea, several well-known brands of Pu 'er tea, various commemorative cakes and commemorative bricks. Pu 'er tea is generally collected by pressing Pu 'er tea, because Pu 'er tea is small in size and area and easy to collect. Pu 'er tea collection is better to collect raw cakes, bricks, melons and melons. Pu 'er tea, handicrafts, mainly for viewing, has no collection value. Among the raw teas, the wild ancient teas from several ancient tea mountains are the best. The wild ancient tea mentioned here mainly refers to the artificially 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 avoid direct sunlight, be clean and ventilated, and have no peculiar smell. If the storage capacity is large, a special warehouse can be set up for storage; If the quantity is small, individuals can store it at home or in ceramic jars. Take out all kinds of bamboo shoots from Pu 'er loose tea and pressed tea, put them directly into the jar and seal the jar mouth.
