Steaming ingredients: Each steaming session takes at least two hours. After selecting the raw materials, put the sorghum into the crusher and crush it. Then, add the auxiliary ingredient rice bran, sprinkle with water, and put it into the steamer. There are two large pots in the steaming room. These two large pots can steam more than 1200 kilograms of ingredients. Each steaming session takes at least two hours. ?

Fermentation: The raw materials generally need to be fermented for more than ten days. In the huge fermentation workshop, there are many neatly arranged large tanks. These large vats are used to hold the raw materials being fermented. During the fermentation period, the raw materials will generate high temperatures and ferment on their own. From the surface, bubbles are constantly rolling. Generally, the raw materials need to be fermented for more than ten days. During this period, the vinegar brewing masters must constantly turn the raw materials to ensure that all raw materials are fully exposed to oxygen. ?

After coming out of the fermentation workshop, the raw materials will pass through a transportation pipeline and enter the fumigation and roasting workshop. The main function of the fumigation and baking process is to color the vinegar. In the fumigation and roasting workshop, large vats are placed on the fire. The temperature in the workshop is very high, especially in summer. When the master workers work here, they often sweat profusely and it is very hard. Under normal circumstances, the raw materials need to be smoked and roasted in the vat for 9 days before entering the next process. ?

After leaving the fumigation and roasting workshop, the raw materials enter the shower room. At this time, boiling water should be added to the raw materials, which is called "soaking in vinegar" in the jargon of vinegar workers. At the bottom of the ingredients is a large sieve, and the vinegar leaks out of the sieve and is pumped into the pot. Chen Xiaowei said that vinegar with different flavors can be made by adding fennel, pepper, aniseed, etc. to the pot at this time. The new vinegar usually stays in the shower room for one day. ?

The new vinegar that has just been poured out contains more water. In order to allow the water in the new vinegar to evaporate quickly, the final process must be carried out: drying the vinegar. The vinegar-drying workshop is one of the workshops with the strongest smell of vinegar. Most people will choke and cannot open their eyes when entering. But after walking around in such a workshop, people will suddenly feel that all seven orifices are psychic, and they can stay away from colds, no matter in winter or summer. Chen Xiaowei said that it takes 24 days from the beginning of steaming to the completion of brewing. After these five steps, the vinegar is stored. The longer the storage time, the stronger the aroma of the vinegar.
