Tanyang Gongfu is one of the three major black teas in Fujian Province. It was passed down from Qing Xianfeng and Tongzhi years (1851 to 1874). It was successfully trial-produced by Tanyang Village in Fu'an City. It has been more than 100 years. The shape is tight and straight, with white, black and black, the inner aroma is fresh and fresh, the soup is golden yellow, the taste is mellow, and the leaves are red and bright.

Tanyang Gongfu originated from Tanyang Village in Baiyun Mountain, Fu'an. It was said that Qing Xianfeng and Tongzhi years (AD 1851 - 1874), and Tan Fu Village had Hu Fusi (also known as Hu Jinsi), and the trial of black tea succeeded. Guangzhou sells to Western Europe. It was very popular. Since then, tea merchants have come to the mountains to seek the market, and they have come and set up foreign banks. After the change of tea layout, they changed from "red" to "green", and there are still few Tanyang efforts. In recent years, through the efforts of relevant departments, Tanyang has recovered and developed. The efficacy of tea 1. Refreshing and refreshing: The caffeine in black tea stimulates the nerve center by stimulating the cerebral cortex, which promotes refreshing and concentration of thinking, which makes the thinking reaction more sensitive and memory enhanced. It can also accelerate the excretion of lactic acid (to make the muscle feel tired). The substance and other old waste materials in the body to achieve the effect of eliminating fatigue. 2, Shengjin Qingre: drinking black tea in summer can quench the thirst, because the polyphenols, sugars, amino acids, pectin in tea and other chemical reactions with the mouth, and stimulate the secretion of saliva, causing the mouth to feel moist, and produce cool sense. 4, diuretic: in the combination of caffeine and aromatic substances in black tea, increase the blood flow of the kidneys. Increased glomerular filtration rate can alleviate edema caused by heart disease or nephritis. 5, anti-inflammatory sterilization: polyphenols in black tea have anti-inflammatory results, so bacterial dysentery and food poisoning patients drink black tea is quite beneficial. 6. Detoxification: According to experiments, tea polyalcohol in black tea can absorb heavy metals and alkaloids and precipitate and decompose. This is a boon for modern people who suffer from industrial pollution of drinking water and food. 7. Nourishing the stomach and protecting the stomach: After the black tea is fermented and baked, the polyphenols undergo an enzymatic oxidation reaction under the action of oxidase, and the content is reduced, and the irritation to the stomach is reduced. 8. Strong bones: The study pointed out that people who drink Tanyang Gongfu black tea have strong bones, and the polyphenols (also in green tea) in Tanyang Gongfu black tea have the ability to inhibit the destruction of bone cell material. In order to prevent and treat common osteoporosis in women, it is recommended to take a small cup of Tanyang Gongfu black tea every day for a few years. For example, adding lemon to Tanyang Gongfu black tea, strong bones, the effect is stronger, can also add a variety of fruits in Tanyang Gongfu black tea, can play a synergistic role. 9. Antioxidant and anti-aging: The results show that antioxidants in green tea and Tanyang Gongfu black tea can completely destroy the path of chemical substances in cancer cells. Dr. Murray Mitterman, director of cardiovascular epidemiology at the Boston Beth Israel Deaconess Medical School, said: "The efficacy of Tanyang Gongfu Black Tea is roughly the same as that of green tea, but the antioxidants of Tanyang Gongfu Black Tea are much more complicated than green tea, especially It is more beneficial to the heart." The American magazine reported that Tanyang Gongfu black tea has stronger anti-aging effects than garlic head, broccoli and carrot. 10, diastolic blood vessels, beneficial heart: The study found that heart disease patients drink 4 cups of Tanyang Gongfu black tea every day, vasodilatation can be increased from 6% to 10%. When the average person is stimulated, the diastolicity will increase by 13%.

Tanyang Gongfu quality technical requirements (a) tea tree varieties. Local vegetable tea is an excellent strain. (2) Site conditions. Altitude 200 meters to 700 meters; soil type: red soil, yellow soil; soil organic matter content ≥ 2.0%; pH value of 4.5 to 6.0; slope u003c25 degrees. (3) Tea planting. 1. Mode of reproduction: sexual reproduction and asexual reproduction. (1) Sexual reproduction: The mature tea seeds in the local tea garden are harvested before and after the frost, and soaked in water for 5 to 7 days in December or January of the following year. (2) Asexual reproduction: In October each year, tea branches with excellent tea garden traits are selected, and seedlings are planted by short-stem cutting technique. From October of the following year to January of the next year, the field is transplanted. 2. Specifications: Planting is divided into two ways, one is cluster type, and the other is single line type. The cluster tea plantation density is about 600 clusters per 667 square meters (mu). The single-row strip planting density is about 3,000 per 667 square meters (mu). (4) Tea garden management. Tea garden fertilization is based on organic fertilizer. The adult tea garden is applied with base fertilizer from September to October, and can be applied to farmyard manure or piled rapeseed cake in combination with autumn deep tillage. Topdressing combined with spring cultivating sorghum for cake. The young tea tree is cultivated by stereotypes to cultivate a high-yielding tree. (5) Fresh leaves are picked. The picking criteria are from one bud to one leaf. Picking is required to be collected in batches in time, with the same shape, size and color. Insect buds, frost buds and purple buds are not taken. (6) Processing. 1. Processing procedure: fresh leaves → withered → 揉捻 → fermentation → dry. 2. Processing equipment: tea machine, withered tank, deblocking machine, fermentation equipment, dryer, air sorting machine, packaging machine. 3. Withering: The weight loss rate is 35% to 42% of the fresh leaf weight, the leaf color turns dark green, the leaf is soft, the tender stem is broken, the green gas disappears, and there is fragrance. 4. 揉捻: The withered leaves are required to curl into more than 90%. 5. Fermentation: The fermentation chamber temperature is 26 ° C to 30 ° C, and the humidity is 90% to 95%. Fermentation time, spring tea 3 to 6 hours, autumn tea 1 to 2 hours. More than 90% of the leaves are copper red, giving off a tea fragrance. 6. Drying: According to the principle of “high temperature, fast and short time”, it is divided into two dryings, and the middle is cool. After initial baking, the water content of tea leaves is about 25%. After full fire, the water content of tea leaves is 5% to 6%. . . (7) Quality characteristics. 1. Sensory index: The rope is tight and straight, the color is black and oily, the soup color is red and golden, the taste is fresh and sweet, the leaf bottom is red and smooth, and the quality of sweet-scented osmanthus is characteristic. Grade appearance, inner quality, rope, cleanness, purity, color, aroma, taste, soup, color, leaf, bottom, super fat, tight, clean, oily, golden, revealing, fresh, rich, fresh, mellow, red, golden, bud, fat, even, red, bright, first-class, tender Tight multi-peak seedlings are evenly cleaned, black, tender and fragrant, rich and fresh, rich, mellow, red, soft, tender, multi-bud, red, bright, second-grade, fat, firm, firm, and even, relatively smooth, relatively clean, bright, fresh, rich, fresh, rich, red, bright and tender. There are buds red bright three-grade fat tight and fine even and still slightly slightly tender stems Wu Shangrun concentrated pure alcohol still thick red bright and tender red is still bright 2. Physical and chemical indicators: project indicators special grade 1-2 grade 3 moisture /% (quality score ≤ 7 total ash /% (mass fraction) ≤ 6.5 powder /% (mass fraction) ≤ 0.5 ≤ 1.0 ≤ 1.5 water extract% ≥ 32 ≥ 30
