Geographical indication

Pu'er tea is an agricultural product, and theoretically, all agricultural products have an expiration date. After the expiration date, the internal components of the tea are oxidized, losing their taste and aroma. There isn't a definitive time limit for the specific expiration date of Pu'er tea. Does Pu'er Raw Tea Have an Expiration Date? Pu'er raw tea: The expiration date and optimal tasting period are generally 10 to 20 years. Pu'er raw tea has rich internal qualities, so it transforms during storage and can be preserved for a long time. Pu'er ripe tea: The expiration date is typically 8 to 15 years. Ripe tea has more stable properties compared to raw tea and can still be stored for a long time, albeit for a shorter duration. For personal or household storage of Pu'er tea, basic requirements include "avoiding light," keeping in a cool place, ensuring there is no odor or pollution, proper ventilation, and avoiding excessive humidity. If possible, individuals or households should have a dedicated "tea storage room" or "tea cabinet." Avoiding light includes not only direct sunlight but also artificial lighting. Pu'er tea should be stored under "natural light." The tea should not be directly exposed to sunlight…

In recent years, Yunnan Province has continuously transformed its resource advantages into strengths for green development, driving the growth of the Yun tea industry. These tiny leaves clearly embody the concept of "lucid waters and lush mountains are invaluable assets." How can we continue to consolidate the advantages of Yun tea? In my opinion, we should focus on quality and safety, brand cultivation, and industrial integration to enable "small tea leaves" to make a "big splash." To enhance quality, we must ensure product safety. Green is the foundation of Yun tea's development, and we need to adhere to a green development path without compromising on quality and safety. Firstly, we should promote green supply. We should improve tea garden infrastructure, support the improvement of low-efficiency tea gardens, comprehensively implement green production in tea gardens, and promote a transformation towards green and low-carbon production methods to create an "ecological tea." Secondly, we should standardize production. We should guide tea enterprises to adopt clean and standardized production practices, strengthen supervision of the quality and safety of tea products during production, processing, and sales, and create a "reassuring tea." Thirdly, we should implement digital traceability. We should actively develop and utilize anti-counterfeiting label…

Puer tea is a geographical indication product of Yunnan Province, and as the provincial capital, Kunming serves as the distribution center for Puer tea across China and worldwide, playing an irreplaceable role in its development. Located at a low latitude (25°N, 103°E) and high altitude (1892m), Kunming experiences a spring-like climate year-round, influenced by atmospheric circulation, geographic location, and altitude. The seven-son cake tea is one of the main representative shapes of Yunnan Puer tea. A single cake often represents the smallest sales unit, and the weight of a single cake (commonly known as the cake weight) should comply with the requirements of JJF1070-2005, "Rules for Metrological Inspection of Net Content of Quantitatively Packaged Commodities." The researchers conducted experiments in Kunming, storing 10 cakes each of raw and ripe Puer tea. They recorded the daily cake weights and temperature and humidity values over a period of 12 months. During the 12-month storage period, the monthly average cake weights of both raw and ripe Puer teas fluctuated. From the seventh month (February 2019) to the tenth month (May 2019), there was a dry and hot climate with temperature values exceeding humidity values for four consecutive months. During this time, the monthly…

Xu Yahé: The premise for 'aging to richer flavor' is to get the initial setup right for Pu'er tea The tea expert Xu Yahé once introduced a new concept of Pu'er tea storage called "Nurture, Guide, Influence, Control." Based on this concept, with his rich experience in making tea and participating in numerous Pu'er tea evaluations, he will explain how to achieve the initial setup for Pu'er tea's 'aging to richer flavor' before its production, following national standards. He hopes to provide readers with useful information and insights. Want 'aging to richer flavor'? First, check if it’s the right 'material' According to Xu Yahé, from the perspective of raw materials, the results for 'aging to richer flavor' differ for first-grade, second-grade, and third-grade teas. "I believe that the concept of 'aging to richer flavor' is targeted at specific teas, guiding and controlling their quality in a particular direction. Only good-quality teas are worth storing; otherwise, they should be consumed sooner." To Xu Yahé, Pu'er tea storage is like a school where only the best students with solid foundations can enter. What constitutes a good foundation? First, select the right material Which type of tea has the initial conditions to reach…
