Bingdao Village is located between 23°34' and 24°38' north latitude, with an altitude of 1600-2200 meters, an annual rainfall of 1800 mm, and red soil rich in organic matter4. This "high altitude, high humidity, high organic matter" environment has created the unique "rock sugar sweetness" of Bingdao Tea. What's even more amazing is that Bingdao Village is divided into the east and west half of the mountain by the Nanmeng River:
- West half of the mountain (Iceland Old Village, Nanpo, Dijie): weak sunshine, mellow and strong tea soup, overbearing tea aroma;
- East half of the mountain (Bawai, Nuowu): sufficient sunshine, soft and elegant tea soup, long-lasting sweetness.
Iceland Old Village combines the strengths of both mountains and has become the "culmination of taste" in Pu'er tea1 。
Bingdao Village was originally named Bingdao (which means "a place with bamboo fences as a village gate" in Dai language). Its tea-growing history can be traced back to the Chenghua period of the Ming Dynasty (1485). According to the Shuangjiang County Annals, the Dai chieftain once presented Bingdao tea as tribute tea to the imperial court, and it was named Bingdao because of its "sweet soup like honey and fragrant like orchids”12 。In the 1980s, Iceland tea was listed as a national fine variety (Mengku large-leaf variety) due to its excellent quality and became the core raw material for the standardized production of Pu'er tea.2
The production process of Iceland Pu'er tea can be called "the art of time":
- Raw tea process:
- Picking: Only one bud and two leaves are picked to ensure the fresh leaves remain tender;
- Sun drying: Sun drying preserves active enzymes and forms the "rock sugar flavor";
- Pressure: Press the cakes with a stone mill, and the tightness is controlled at 65%, which is conducive to later aging.
- Ripe tea process:
- Pile fermentation: Fermentation at a constant temperature of 45-65℃, where the microbial community stimulates the production of theabrownin;
- Storage transformation: After being stored in a dry warehouse for more than 5 years, the tea soup changes from golden yellow to red and has a mellower taste.9 。
Icelandic tea companies such as Bama Tea have adopted a "one tree one code" traceability system to ensure that every piece of tea comes from a century-old tree.8 。
The taste of Icelandic tea is as rich as a symphony:
- Top note: The soft tea soup melts in your mouth, with the fragrance of wild orchids and the sweetness of honey;
- Middle note: The tea soup gradually enters the throat, and the slight astringency quickly turns into sweetness, which makes your body gushing;
- Base note: The fragrance at the bottom of the cup lasts for a long time, and the aroma of rock sugar lingers between your teeth, and the aftertaste lasts for several hours11 。
Professional tea expert Deng Shihai once summarized the charm of Icelandic tea with eight characters: "fragrant, sweet, sweet, bitter, astringent, refreshing, fragrant, and aged". Its tea polyphenol content is as high as 33.8% and caffeine is 4.1%, which is worth drinking and collecting.2 。
- Price trend:
- Ancient tree spring tea: 3500-4500 yuan/kg (up 15% year-on-year in 2024);
- Big tree tea: 1500-2500 yuan/kg, outstanding cost performance5 。
- Collection Trends:
- In 2014, the transaction price of Iceland ancient tree tea exceeded 100,000 yuan per cake, with an annual appreciation rate of 20%;
- In 2020, the first spring tea became the "hard currency" in the market due to its excellent quality13 。
- Risk Warning:
- The counterfeit rate in the market exceeds 60%. It is recommended to choose brands with geographical indication certification;
- Storage conditions are crucial, and dry storage can avoid "wet warehouse smell"14 。
The health benefits of Icelandic Pu'er tea have been confirmed by many studies:
- Lipid reduction and weight loss: A study by the Saint-Antoine Medical School in Paris, France, showed that tea polyphenols can reduce cholesterol by 20%;
- Regulate blood sugar: Theabrownin activates insulin receptors and improves glucose tolerance;
- Anti-aging: Catechins have 20 times the ability to scavenge free radicals as vitamin C.16 。
The latest research in 2024 found that tea polysaccharides in Icelandic tea can regulate intestinal flora and alleviate obesity-related metabolic syndrome16 。
从From the Dai language "Bingdao" to the world's tea king, Iceland Pu'er tea has witnessed the wisdom of Yunnan's ethnic minorities and the gift of nature. In 2024, with the implementation of the "Yunnan Ancient Tea Tree Protection Regulations"7 ，This land is continuing its legend with "protective picking". Whether for drinking, collecting or investment, Iceland tea is the "golden key" to open the world of Pu'er tea.
