In the early years of the Qing Dynasty, Yiyuanqing's vinegar-making technology was introduced to the people. By the twenty-second year of Jiaqing (1817), Yiyuanqing Laodian had a daily output of 150 kilograms of vinegar, which was the largest vinegar-making workshop in Shanxi at that time. Since then, although Yiyuanqing has changed hands several times, the quality of the vinegar has always been the same, and the trade has endured. Today, the former Ninghua Mansion is not a symbol of the dignity of the princes, but the Yiyuanqing vinegar named after it is as mellow as before, and has become a time-honored brand in the vinegar industry loved and trusted by Taiyuan people.

Yiyuanqing vinegar is a traditional solid-state fermentation process, which is used to increase color and flavor by fumigation in the later stage, and the vinegar is fragrant, sour, sweet and cotton, brown and red in color, and mellow in taste. These characteristics are inseparable from the unique craftsmanship formed by Yiyuanqing for hundreds of years. In terms of ingredients alone, Yiyuanqing's main ingredients, high-quality sorghum, auxiliary materials, chaff, etc., must be strictly selected. While there can be substitutes for these ingredients in brewing theory, centuries of practice have shown that any slight change in the recipe of traditional ingredients will change the flavor of the vinegar. Therefore, in the process of development, Yiyuanqing adheres to the essence of traditional skills, steaming, fermentation, smoking, drenching, brewing, blending, and every link is refined. "Mian, sour, sweet, seasoning, and food, Chinese people compete for Sanjin vinegar, steaming, fermentation, smoking, summer sunning, winter fishing, who knows the hardships here."
