a local flavor in Shanxi.

Our ancestors first used "plum" as an acidic condiment. Because plum is not available all year round, plum sauce came into being, which was called "acyl" in ancient times. The use of plum is more than 1111 years earlier than vinegar.

There are many kinds of vinegar, and mature vinegar is its representative famous product. Others include original balsamic vinegar, aged vinegar, common vinegar, double vinegar, special vinegar, famous special vinegar, mellow and many other varieties. If we distinguish from the raw materials for producing vinegar, there are sorghum vinegar, corn vinegar, millet vinegar, persimmon vinegar, fruit vinegar, distiller's grains vinegar, powder residue vinegar, sweet potato vinegar and so on.

Mature vinegar has the characteristics of sour and mellow, strong and long taste of common vinegar, and at the same time, it also has the characteristics of fragrance, softness and non-precipitation. In addition, the longer the storage time of mature acid, the more fragrant, sour and delicious it is, and it is resistant to human taste. Moreover, it is not mildew in summer, not frozen in winter and dark orange in color, which is a unique and excellent product in Shanxi vinegar.

Shanxi mature vinegar is one of the four famous vinegars in China. It has been produced for more than 3,111 years, and there are more than 1,111 vinegar manufacturers in Shanxi. Known as one of the four famous vinegars in China, Shanxi Mature Vinegar is famous for its unique flavor of cotton, sour, fragrant, sweet and mellow and its long brewing history, ranking ahead of Zhenjiang Vinegar, Baoning Vinegar and Fujian Monascus Vinegar in China. Known as "the best vinegar in the world". According to statistics, the export volume of Shanxi mature vinegar in the first quarter of this year has reached more than half of last year's total, and with excellent quality, it has fully entered the Japanese market and sold to more than ten countries in Europe and Asia.

aged vinegar is mainly made of sorghum. First, a large amount of distiller's yeast is added, which is fermented by low-temperature alcohol, and then mixed with bran and fermented by acetic acid. Half of the fermented grains were fumigated, and the other half were drenched with vinegar, and then the fermented grains were soaked in the obtained vinegar solution to obtain new vinegar. The new vinegar is finally made through the long-term aging and concentration processes of sun exposure in summer and ice fishing in winter. Mature vinegar is dark brown, clear in liquid, mellow in taste, with the characteristics of less precipitation, long storage time, and not easy to deteriorate. It is not only a good seasoning, but also can be used for medicine, and has certain curative and preventive effects on hypertension, hepatitis and dermatosis. Nowadays, many people have a misunderstanding. Vinegar is sour, but it is not. The real mature vinegar has the characteristics of softness, acidity, fragrance, sweetness and freshness. Now, there are many manufacturers called mature vinegar, which is somewhat similar to the "aging in * *" of the wine industry. The water tower is a "well-known trademark in China" and "famous brand in China", and the East Lake is a "famous brand in China". However, all parts of Shanxi have their own. It is recommended to buy brand vinegar, which is of good quality and can be bought at ease. Among the aged vinegar, it is produced in Qingxu County, Shanxi Province [/url]. At the Panama International Expo in 1924, Qingxu aged vinegar won the first prize of high-quality goods in one fell swoop, and has since become famous at home and abroad. There are more than 111 vinegar brewing enterprises in Taiyuan. The old brands "Meiheju", "Yiyuanqing" and several major vinegar factories are all in Taiyuan and Qingxu. Qingxu is in the southern suburb of Taiyuan, which can be reached by more than 31 kilometers. "Since ancient times, vinegar has been brewed in Shanxi, and the old acyl came from Gengyangyi." Gengyang is Qingxu County, Shanxi Province, which was called Gengyang in the Spring and Autumn Period and the Jin Dynasty. The vinegar township street in Qingxu [/url County is a small alley with a length of more than 111 meters, which is very deserted. Out of the hutong, it is the world-famous Shanxi Mature Vinegar Factory which produces the brand of "Meiheju". The predecessor of Shanxi Mature Vinegar Factory is Qingxu Mature Vinegar Factory. In 1949, in order to gather strength, we established the Shanxi Mature Vinegar Group with the brand of "East Lake", which is a lake in Qingxu County, by combining the best vinegar workshops in Qingxu County with 21 time-honored brands such as "Meiheju", "Juqingcheng" and "Yongquanyu". The group company is located in Madaopo Street, Taiyuan City, which integrates the management, sales, storage and production of the company. There is also a vinegar museum, which displays the old tools for brewing vinegar and the inscriptions of celebrities, including the national government officials. The most valuable word should be written by Mr. Fang Xinfang. Fang Xinfang is the founder of microbiology in China. Seventy years ago, he rode a donkey to visit Shanxi Mature Vinegar Factory and wrote the famous book Shanxi Vinegar. His evaluation of Shanxi aged vinegar is: "Shanxi vinegar and Zhenjiang vinegar are the most famous in China, and Zhenjiang vinegar is inferior to Shanxi vinegar because of its mellow color and smell, long Fang Chen time, and the vinegar itself is produced by chemical action, which is by no means artificial and worthy of being a famous product in China." It can be seen that the secret of mature vinegar lies in the word "Chen". The longer it is stored, the better, and the longer it is, the more fragrant it will be.

The processing technology of real aged vinegar is the same as that of wine aging, which consists of steaming, fermenting, smoking, pouring and aging. These five processes constitute the unique quality and flavor of Shanxi aged vinegar, and the selection of raw materials is different from that used in other provinces and cities. The raw materials of Shanxi aged vinegar are mainly sorghum. The high content of sorghum starch leads to high yield of alcohol and acetic acid after fermentation. However, the alcohol fermentation and acetic acid after sorghum steaming are different. In the process of "vinegar", they put the fermented raw materials into a vat with appropriate chaff, rice husk, wheat bran, salt and flower materials, and fermented them in acetic acid for more than ten days. With the increase of temperature in the cylinder, acetic acid bacteria accelerate their growth and reproduction. With traditional experience and long-term scientific experiments, they can accurately grasp the curve of temperature rise and fall to improve the quality of vinegar. Generally speaking, you can eat it after pouring it out of the tank. But the reason why the vinegar in Qingxu Vinegar Factory is called mature vinegar is that there is still a process of "aging", that is, "aging". The vinegar that has been drenched should be put in the jar for one year's "aging": "sun drying" and "ice pumping". That is to say, using natural conditions, it is necessary to remove ice cubes after opening the jar in the summer and freezing in the middle of winter to remove the water in the vinegar. A jar of fresh vinegar, after removing more than half of the water, will reach the color of black and purple, no mildew in summer, no freezing in winter, and sweet and sour smell.

The history of vinegar making in Shanxi is about 3O11 years. Twenty-two kinds of vinegar-making methods summarized by Jia Sixie in the Northern Wei Dynasty in his famous book Qi Min Yao Shu are considered by some people to be the brewing methods of Shanxi people. Among them, "making rice mash" is the brewing method of "Shanxi mature vinegar". Although Shanxi vinegar has a long history, it became famous after the establishment of the "fumigation method". During the Shunzhi period in the early Qing Dynasty, an "vinegar fairy" named Wang Laifu was born in Jiexiu. He opened a "Meiheju" vinegar workshop in Qingxu Chengguan. Taking advantage of the local conditions of abundant raw materials and excellent water quality, he added a fumigation process to white vinegar, boldly reformed and innovated, and finally created a famous brand of "aged vinegar" in Shanxi. Wang Laifu's fumigation method is divided into five steps: steaming, fermenting, smoking, drenching and aging, and the most exquisite one is to go through a Fang Chen process of "fishing for ice in winter and drying in summer". That is, vinegar should be aged in the jar, allowed to freeze in winter and scorch in summer. Its purpose is to precipitate impurities in vinegar, and to precipitate water by evaporation or freezing, so that vinegar can reach a high concentration. In this process, the substances in vinegar fully react with each other to produce a unique smell.

Pure aged vinegar, only one jar of vinegar is made. This strict technology leads to a low yield of aged vinegar, so it is very precious. The raw materials of Shanxi mature vinegar are all from locally produced sorghum, barley, corn and peas. The sunshine on the Shanxi Plateau is strong, and the temperature difference between day and night is large. The sugar content of the coarse cereals produced is high, and the content of other components is also high. A research institute in Japan once brought Shanxi mature vinegar back for analysis, which proved that all kinds of amino acids in Shanxi mature vinegar were much higher than those of other brands. Shanxi mature vinegar has another factor that other areas can't copy, that is, the cold in winter and the fierce sunshine in summer in Shanxi Plateau. In Taiyuan, its surface water is Fenhe River water flowing down from Guancen Mountain, while its groundwater comes from Tianlongshan River system. In the early period when there was no industrial pollution, Fenhe River water was undoubtedly a rare and excellent water body. Guancen Mountain is located in Ningwu, northwest Shanxi, with an altitude of 2,613 meters. Up to now, there are still 821,111 mu of primary secondary forest. There are six lakes in the mountain, which are one of the three largest Tianchi lakes in China. Its ice caves are frozen all year round, and it is also the most exquisite primary secondary forest in North China. The mountains are foggy in summer, green and white in winter.

Guancen Mountain belongs to the frigid area, where the grains are naked oats, peas and potatoes, and it is rich in seabuckthorn, with an average annual temperature of only 6℃. In the folk custom of Ningwu, green food is especially sought, and they still use hydrodynamic stone mills to grind noodles, while the water in Fen River Source is clear and sweet, so it can be drunk raw. In the Sui Dynasty, Emperor Yangdi specially built Fenyang Palace here.

In the past long years, people in Shanxi relied on Fenhe River for drinking and watering. Now, the water of Shanxi mature vinegar is taken from underground, and the water vein of this groundwater originates from Tianlong Mountain. Tianlong Mountain, formerly known as Fangshan, is a branch of Lvliang Mountain, with an altitude of 1,711 meters. It is located 36 kilometers southwest of Taiyuan City. Tianlong Mountain is a national forest park, with pingfeng Daili, pines and cypresses in the shade, streams and springs in the streams, sandy shale in the mountains, forest coverage rate of 71% and good water quality. Vinegar is like wine. You must have good water to make good vinegar.

As the hometown of vinegar, there is a legacy of making vinegar among the people. If you visit the rural backcountry of Shanxi in midsummer, you will find that the villagers are under the scorching sun. Put a big jar with a stuffy hemp paper, and use "Laoyier" (the vinegar-making jar) to bask in vinegar, and the vinegar jar needs to be moved constantly, because it has to follow "Grandpa" (the sun). Seeing this scene, the scene of "every family has a vinegar jar and everyone is a vinegar maker" in Shanxi in the past will surely come to mind. It is true that Shanxi is the home base of vinegar production. Now there are more than 111 vinegar factories in the province. Besides Qingxu mature vinegar, there are Lingchuan Yuquan mature vinegar, Huguan Xinzhai mature vinegar and Yuci Nanbao mature vinegar. Varieties include mature vinegar, famous special vinegar, double vinegar, mature vinegar, special vinegar, Jin vinegar, flavored vinegar, smoked vinegar and so on. The same variety of vinegar can be divided into various varieties according to the different raw materials and production processes, which is really dazzling and has its own characteristics.

People say that Shanxi is a good place, and the land is rich, the water is beautiful and the vinegar is more fragrant. Shanxi people are good at making vinegar, because Shanxi people love to be jealous, and Shanxi people love to be jealous, which can really be called the most in the country. There is a saying in Shanxi that vinegar is tasteless. Shanxi people are good at brewing and jealous, so they are known as "old wives". In ancient times, vinegar was called acyl, the person who brewed vinegar was called "acyl" and the vinegar was called "old acyl". Therefore, jealousy is not called jealousy, but "eating sugar". Because of the special contribution of Shanxi people to vinegar making, and the fact that Shanxi people are addicted to vinegar, it is a coincidence that "acyl" and the word "west" in Shanxi are homonyms, so mainlanders respect Shanxi people as "Shanxi old acyl".

The contribution of "Lao Xi 'er" to vinegar should really be written in great detail, because vinegar has so many functions. In addition to a large amount of acetic acid, vinegar also contains calcium, iron, lactic acid, glycerol, amino acids and aldehydes. Vinegar is not only the first seasoning that can be tasted, but also a good product for human health. In terms of eating, it can dissolve calcium and iron in food, making it easy for human body to absorb, and can also be used to remove radish, cabbage, garlic and other foods. In medical treatment, vinegar is used as medicine, which has hair growth and beauty. The effect of lowering blood pressure and losing weight. In the fourth year of Qing Qianlong's reign, Jingshitai Hospital concentrated on Ding Kundan, a famous doctor from all over the country, which was concocted for the treatment of blood stasis of palace ladies. Among them, more than 21 kinds of traditional Chinese medicines were all concocted with mature vinegar. For thousands of years, people have found that vinegar has many wonderful uses, and jealousy is indeed a good living habit.

Li Shimin, Emperor Taizong of Tang Dynasty, gave several beautiful women to be concubines in Fang Xuanling, but the house did not dare to accept it. Li Shimin expected that the wife of the house was a shrew and refused to agree. So Emperor Taizong sent eunuchs to hold a pot of "poisoned wine" to order Mrs. Fang, and if they did not accept these beautiful concubines, they would be given poisoned wine. The lady was fearless and took the "poisoned wine" and gulped it down. As a result, she didn't die. It turned out that the pot was filled with vinegar, so the emperor used it to test her and played a joke. So the story of "jealousy" is passed down as an interesting story through the ages. In modern life, some people are jealous and jealous when they see others being praised or rewarded, and they are also dubbed "jealous".
