Luzhou-flavor liquor is mud pits fermentation containers, grain for liquor-making raw materials such as sorghum, wheat or additions such as barley, sorghum medium temperature daqu as the wine color agent, with continued bad made from ingredients, mix evaporate &coal mixing process and become a kind of white wine, the wine with ethyl caproate as main flavoring substances.

In 1979, the third national wine appraisal conference was held, which established a typical representative of luzhou laojiao special wine, which is also called luzhou-flavor liquor. 1957 national organization expert group sea-front luzhou laojiao (a kind of daqu liquor), the luzhou LaoJiaoJiu assessment systematically summarized brewing process, opening of scientization of Chinese liquor, and became a good beginning for luzhou-flavor liquor brewing technology development, the development of luzhou-flavor liquor brewing technology for 50 years, for luzhou-flavor liquor liquor market share of more than 70% have laid a solid foundation.



Following the development of the making technology, the system has experienced the following stages:

First stage: a single small traditional wine making workshop, the use of high temperature hot season does not like wine, but environmental microbes very active "hot season off", thatched cottage "v" for the use of wine a year.

The second stage: multiple wine-making workshop of the joint venture, wine starter demand growth, scale and organization that starter-making team (workshop), using the air temperature is warm, environmental microbial relatively active in October 4 - bungalows WaWu starter, making for the use of wine a year.

The third stage: building type, yongji, specialized companies, the interaction of microorganisms with curved billet environment, made starter-making ecological garden, the advantages of microbial flora implements the system of the four seasons, starter in the regional resources and products as circulation of commodities, for liquor quality starter quality laid the foundation of the ascent of the whole.

1.1 mechanized billet technology

In view of the traditional artificial mixing materials, artificial on starter-making billet caused the defect of labor productivity, such as study realized the mechanical mixing materials, artificial on starter-making billet, mechanical mixing materials, machinery blocking, reduce the workers labor intensity and improve labor productivity. 1.2 micro oxygen koji making technology For mechanical assembly line blocking grouting effect is poor, lead to curved surface no nutritional advantage of objective conditions, to create a "starter fermentation and anaerobic environment" theory, the method of curved billet moisturizing of bao chao on oxygen march billet with bacterium fermentation, enhance the moisturizing effect on the surface of the billet, curved surface microbes to grow well, significantly improve the system of choepel bacteria fermentation process of dressing, starter microbial cultivation in anaerobic environment, strengthen the adaptive confined within the pits after formation of the micro oxygen fermentation performance.

1.3 qu billet bacteria culture turning technology for traditional fermentation process of bacteria culture gradually approach stacking type double curved technology, there are marked ups and downs of curved billet temperature affect the stability of the microbial, play gathering stacking defects such as labor intensity, research has formed a "bacteria culture fermentation - double curved stacking translational fermentation" of the song. The environment condition of billet fermentation is stabilized, the labor intensity of workers is reduced, and labor productivity is improved.

1.4 support curved billet needle rice husk, straw covering technology as support covering curved billet cause dust pollution of the environment, the messy, high material consumption, defect. Research has formed the ferula, careless, ferula, film, ferula, such as woven cloth as support covering curved billet. Clean the production site, improve the working environment, control the material consumption.
