Brewing Techniques of Qingxu Old Vinegar

Qingxu old vinegar brewing skills, Shanxi Province Qingxu County local traditional skills, one of the national intangible cultural heritage.

The brewing process of Qingxu aged vinegar is complex. After the main steps of ingredients, steaming, manual turning of solid acetic acid, high temperature fumigation, high density leaching, aging and so on, more than ten processes eventually produce Qingxu aged vinegar.

On May 20, 2006, the brewing technology of Qingxu old vinegar was approved by the State Council of the People's Republic of China and listed in the first batch of national intangible cultural heritage list, item number_-61.

historical origin

In ancient China, vinegar was called oxalic, anhydride, bitter wine or wine. As early as 700 years ago in the Spring and Autumn Period and the Warring States Period, the Qingxu people had been using VATS and urns to make vinegar by liquid fermentation, and this vinegar-making technology has continued. In the Western Han Dynasty, commercial vinegar-making workshops appeared in Qingxu. During the Northern Wei Dynasty, the technology of vinegar brewing changed from liquid fermentation to solid fermentation. This milestone pioneering work laid the foundation for the formation of the unique style of the old vinegar brewing technology in Qingxu.

In Qi Min Yao Shu, later Wei Jia Sixie elaborated the process of vinegar brewing in detail. Historian Hao Shuhou's textual research on Taiyuan shows that before 479 BC, "when Jinyang City (now Jinyuan Town, the southern suburb of Taiyuan City) was established, there should be vinegar makers." Foreigners call Shanxi people "Lao Xier", which is the homonym of the ancient word "Jiu". Taking the ancient vinegar character as the pronoun of Shanxi people can also reflect the early and large number of vinegar brewing in Shanxi in history.

In the late Ming and early Qing Dynasties, vinegar-making workshops were everywhere in villages and towns in Qingxu County, south of Taiyuan Prefecture. In the long historical competition of vinegar industry, there is a workshop called Yiyuan Qing, which has gradually gained fame. "Yiyuan Qing" vinegar brewing, which pays great attention to quality, excellent material selection, appropriate formula, complex production process, is well received by the masses, and has been operating until the eve of liberation. Its brewing method is used by Qingxu Vinegar Factory. Qingxu and Taiyuan are the birthplaces of Shanxi old vinegar. Qingxu brewing technology is gradually being promoted to all parts of the country.

Technological characteristics

Qingxu old vinegar produced by the brewing techniques of Qingxu old vinegar is black-brown, bright and attractive. In addition to its three advantages of acid and alcohol, strong taste and long taste, it also has the characteristics of fragrance, cotton, non-precipitation and "hanging bowl".

When the cap of the old vinegar bottle is unscrewed, the fragrant and sour smell will come to your nose, drop it into the bowl and beat a circle, then stick it evenly to the edge of the bowl. Although the acidity of Qingxu old vinegar is five degrees, it tastes not difficult to endure. Instead, it is "sweet and fragrant and sour", which is slow, long and delicious. It is sour and sweet, spongy and fragrant.

General vinegar stored for a long time, will become turbid, raw white skin, and even decay. But the longer the vinegar is stored, the more fragrant it will be. Even if it turns into a solid vinegar like heavy amber after several decades, it will still be fresh and sour when it is washed away with boiling water.

Unlike the long-term consumption of fruit vinegar in the West, vinegar fermented from cereals is the first choice in China, which makes Chinese vinegar contain more essential nutrients such as amino acids. The aged vinegar of Qingxu has the unique functions of breaking off fishy smell, removing humus, removing humus and sterilizing. It is a refined condiment for cooking various delicious dishes.

Technological process

Qingxu old vinegar is made from local high-quality sorghum and red heart Daqu made from peas and barley in Qingxu County. It is brewed with various fur chaff as auxiliary materials. Its production needs more than ten main steps, such as ingredients, steaming materials, manual turning of solid acetic acid, high temperature fumigation, high density leaching, aging and so on.

The reason why Qingxu old vinegar is different from other vinegar is that it has a aging process. The drinked vinegar should also be put in the jar for one year. The aging process makes full use of natural conditions. After opening the jar, ice cubes need to be removed after sunshine in the summer and freezing in the winter to remove the moisture in the vinegar. A jar of new vinegar, after removing more than half of the moisture, will achieve the color of black and purple, summer is not mildew, winter is not frozen, sweet and ISOACID taste.

The technological process of Qingxu old vinegar brewing will have the following major steps: material selection, moistening, mixing, alcohol fermentation, secondary mixing, acetic acid fermentation, fumigation vinegar, vinegar drenching, vinegar aging, packaging and finished products. Detailed process flow can be seen in the flow chart on the right.

Inheritance and Protection

Inheritance value

Qingxu old vinegar is not only a condiment, according to scientific research, vinegar can sterilize, help digestion, prevent colds and cancer. Shanxi Qingxu old vinegar can keep fit, cure diseases and beautify. The acetic acid contained in it has bacteriostatic and bactericidal effects, especially on cocci. Stir-fried vegetables with aged vinegar can treat lumbar and leg pain, apply foot heart can treat hypertension, scaling at the bottom of aged vinegar can treat bone hyperplasia and other diseases.

Among the old vinegar in Shanxi, Qingxu old vinegar is the most authentic. Its exquisite production skills and exquisite material selection are worth learning from other vinegar products.

Current situation of inheritance

Driven by economic interests, some workshops cut corners, dismembered the traditional craft of Qingxu old vinegar, and produced inferior products, which distorted the skills and reputation of Shanxi Qingxu old vinegar, and should be thoroughly managed and strictly guarded against.

Heritage figures

Wu Runwei, male, born in March 1955. In December 2012, Wu Runwei was selected as the representative successor of the fourth batch of national intangible cultural heritage projects, declared by Qingxu County, Shanxi Province. Project Name: Brewing Techniques of Qingxu Old Vinegar.

protective measures

In 2004, the General Administration of Quality Supervision, Inspection and Quarantine of China approved the application for product protection in the origin area of Shanxi aged vinegar, and approved more than ten old vinegar products, including Qingxu County, to be protected in the origin area.

In 2016, Qingxu County was responsible for promoting the construction of vinegar industrial park with an area of 1000 mu. Through the construction of vinegar Industrial Park to promote new technological innovation and research and development, to provide technical support for the sustainable development of vinegar industry.

In 2018, Taiyuan Qingxu Baoyuan Old Vinegar Workshop was awarded "Shanxi Qingxu Old Vinegar Brewing Museum" by Shanxi Provincial Culture Department and "National AAAA Tourist Scenic Area" by the National Tourism Administration.
