Aged vinegar: sorghum is the main material. Firstly, it adds a lot of wine curd and adopts low temperature alcohol for fermentation, and then it is mixed with grain bran bran through acetic acid fermentation. Half of the vinegar grains are smoked, and the other half of the vinegar grains are drenched with vinegar, and then the vinegar liquid is soaked with smoked grains and drenched with new vinegar. The new vinegar is then made into aged vinegar by the long-term aging and concentration process of summer sunshine and winter ice fishing.
Rice vinegar: 1, paste stubble that is boiled rice, soaked millet into the pot, warm fire to cook rice, rice boiled to blossom, into a sticky paste can be. The boiled rice will be spread out to dissipate the heat, when the temperature cools to 38 degrees Celsius, add the quartz and mix it well into the tank for fermentation, add the quartz to play the role of yeast, which can ferment naturally, and make the product have the natural quartz flavor.
2, Fen vinegar: the fermented mash mixed with grain chaff poured into the urn natural fermentation, into the seven days of starch saccharification and alcohol fermentation stage, fermentation with the ear listening to the urn, according to the ringing sound to determine the fermentation.
3, copying the cylinder: into the cylinder fermentation with the hand copied grains, copying the purpose of the cylinder is to increase the temperature, expand the acetic acid in the vinegar grains of propagation, is conducive to the vinegar grains of air circulation, the fermentation process takes two months.
4, dial cylinder: the temperature of the vinegar grains down to the natural temperature of the dial cylinder, from one cylinder into another cylinder, to ensure that the fermentation temperature so that the fermentation is complete.
5, storage of grains: to ensure the taste of millet vinegar, the fermented vinegar grains are put into the tank for storage, after the grains are put into the tank, a layer of millet bran is sprinkled on the upper part, and then it is covered with oil cloth, and finally it is sealed with mud, and the grains need to be stored for three months.
6, dripping vinegar: the most stored vinegar grains into the dripping vinegar cylinder, dripping vinegar cylinder bottom has small holes, the holes put into the skid, the vinegar liquid along the skid flows into the basin, the vinegar liquid in the basin is repeatedly poured into the dripping vinegar cylinder until the vinegar crude liquid is clear, the process takes one hour.
