Production Techniques of Black Tea

brief introduction

Qimen Black Tea is the only black tea among the top ten famous teas in China. It is produced in Qimen County, Anhui Province. Tea production in Qimen has a long history, which can be traced back to the Northern and Southern Dynasties. In the early years of Guangxu in the Qing Dynasty, green tea was not sold well in the international tea market. Hu Yuanlong, a knowledgeable man from Guixi, Nanxiang, was the representative of Qimen Tea District. In the second year of Guangxu (1876), black tea was successfully created. Once Qihong came out, it became famous both at home and abroad for its outstanding quality. In 1915, Qihong participated in Panama International Exposition and won the highest gold medal. In 1987, Qihong won the Gold Prize of the 26th World Quality Food Selection Conference. Two of them won the highest international prize, standing on the top of the world tea. Qimen is also named by the relevant state departments as "the hometown of black tea in China". The traditional Qimen black tea is made by hand. The excellent quality depends on the hands. So Qihong is also called Qimen Gongfu. Qihong tea-making process is divided into two parts: primary processing and refinement. There are four processes: withering, kneading, fermentation and drying. Refining has screening, cutting off, air selection, picking, reheating, even stacking and other processes, without more than 10 years of experience, no less than a painstaking effort, it is impossible to make good tea. The finished Qihong has a dark and moist appearance, tightly roped and beautiful edge. The soup is red and transparent, and the bottom of the leaves is bright red. The most attractive scent is aroma. Tea makers at home and abroad call it sugar or apple fragrance, with orchid fragrance, fragrance lasting, unique, known as "Qimen fragrance", Qihong also ranks first among the world's three high-aroma black tea. More than a hundred years of history, more than a hundred years of brilliance. In July 1979, Deng Xiaoping, a great man of a generation, visited Huangshan and said, "Qihong is famous in the world!" In 1991, Jiang Zemin, then general secretary of the CPC Central Committee, visited the former Soviet Union and chose Qihong as the national ceremony. With the development of the times, Qihong's thick and brilliant history has continuously added a brilliant glory. Qimen black tea is an outstanding representative of Chinese tea. In recent years, due to the influence of domestic and foreign tea market, there have been some problems, such as poor sales, lack of successors of traditional handicraft technology. Therefore, Qimen County Committee and county government attach great importance to it, formulate development plans, take various effective measures, and strive to revitalize Qihong, the most famous brand in the world tea industry. 。

historical origin

The Wechsler Dictionary of the United States, "Qimen Black Tea" records the origin of Qimen Black Tea, Qimen County, Anhui Province, China. Founding year: Qimen tea was created in Guangxunian (AD 1875), which has a production history of more than a hundred years. It can be traced back to the Tang Dynasty. Tea Saint Lu Yu left a record in the Book of Tea: "Huzhou, Changzhou, Shezhou Xia". Qimen belonged to Shezhou at that time.

Around 1875, Hu Yuanlong, a Qimen personage, drew lessons from the method of making black tea in other provinces, and processed black tea in Qimen. Later, he was introduced into Beiping by Tongshengxiang Teahouse in Peiping and succeeded in the market.

In the first year of Guangxu (1875), Hu Yuanlong planned to build Rishun Tea Factory in Peigui Shanfang. He asked Ningzhou Master Shu Jili to make black tea according to Ninghong experience.

Before the reign of Guangxu in Qing Dynasty, Qimen only produced green tea, but not black tea.

In 1875, a man named Yu Ganchen from Yixian County, Anhui Province, went back to his native place to do business. Seeing that black tea was popular and profitable, he set up a black tea farm in Yaodu Street, Dexian County. He imitated the "Fujian black tea" method and began to make black tea.

In 1876, Yu set up black tea branches successively in Qimen West Road Town and Shinli to expand his business. Because of the superior natural conditions and the superior quality of black tea produced in Qimen area, the growing origin, output and reputation of black tea have attracted great attention of tea merchants in the international black tea market. Japanese call it rose and British businessmen call it Qimen.

After eight years of Guangxu (1883), it was finally made into superior black tea with excellent color, aroma, taste and shape, which made Hu Yunlong one of the founders of Qihong.

The disciples and apprentices of Yu Ganchen include Chen Shanghao and others. Since 1875, Chen Shanghao started his own tea house in Likou. He studied in the tea house since he was a child. After many years, he was skilled in learning. Huizhengchong Village set up its own tea shop, Shanghao Square.

Health function

Because black tea ingredients have many pharmacological effects, tasting black tea can not only make people enjoy the elegance of calm and leisure, but also play an economic and gratifying role in health care and cosmetology, which adds to the charm of black tea.

Refreshing and exhausting

Caffeine in black tea stimulates the nerve center by stimulating the cerebral cortex, promotes refreshment and concentration of thinking, thus making the thinking more sensitive and memory enhanced. It also has exciting effects on the vascular system and the heart, and strengthens the heart beat, thus speeding up blood circulation to facilitate metabolism, at the same time promoting sweating and diuresis, thereby speeding up the excretion of lactic acid (muscle sense) in both channels. Fatigue-inducing substances) and other old waste substances in the body can eliminate fatigue.

Promoting fluid metabolism and clearing away heat

Black tea can relieve thirst and heat in summer because polyphenols, carbohydrates, amino acids and pectin in tea react with saliva and stimulate salivary secretion, which results in moisturizing and cooling of the mouth. At the same time, caffeine controls the temperature center of the optic hypothalamus and regulates body temperature. It also stimulates the kidney to promote the excretion of heat and dirt and maintain the physiological balance of the body.


Under the combined action of caffeine and aromatic substances in black tea, the blood flow of the kidney is increased, the glomerular filtration rate is increased, the renal microvessels are dilated, and the re-absorption of water by the renal tubules is inhibited, thus the urine volume is increased. This is conducive to the elimination of lactic acid, uric acid (related to gout), excessive salt (related to hypertension), harmful substances, and alleviate the edema caused by heart disease or nephritis.

Anti-inflammatory and bactericidal

The polyphenols in black tea have anti-inflammatory effects. It was found that catechins can bind to single-cell bacteria, coagulate and precipitate proteins, thereby inhibiting and eliminating pathogenic bacteria. Therefore, black tea is beneficial for patients with bacterial larvae and food poisoning, and strong tea is also commonly used to coat wounds, bedsores and Hong Kong feet.


Theophylline in black tea can absorb heavy metals and alkaloids and precipitate and decompose them, which is a good news for modern people whose drinking water and food are polluted by industry.

Nourishing the stomach

Black tea is fermented and baked. Tea polyphenols undergo enzymatic oxidation under the action of oxidase. The content of black tea decreases and the irritation to stomach decreases accordingly. In addition, the oxidation products of these tea polyphenols can also promote human digestion, so black tea can not only hurt the stomach, but also nourish the stomach. Frequently drinking black tea with sugar and milk can reduce inflammation and protect gastric mucosa, and has certain effect on ulcer treatment.


In addition, black tea also has anti-caries, delaying aging, lowering blood sugar, lowering blood pressure, lowering blood lipid, anti-cancer, anti-radiation, weight loss and other effects.
