According to the ancestral formula, five kinds of grains were mixed, crushed and mixed with a certain proportion of aged old mother grains (fermented grains), and wrapped koji was used as saccharifying starter, and the fermentation period was more than 70 days in the cellar.
The fermentation time at the bottom of the wheel is more than 65,438+0.40 d, and it is made by the combination of traditional pit operation cycle, continuous fermentation, layered fermentation, layered distillation, quality wine picking, quality jar combination, graded storage, long-term aging in pottery jar and sieving. It takes not less than 5 days from the input of raw materials to the delivery of products, and the age of flavored wine is not less than 15 days.
China liquor, represented by Wuliangye, has a brewing history of over 3,000 years, and is one of the oldest and most mysterious food manufacturing industries in the world.

Wuliangye producing area environment
Yibin is located in the core area of "Golden Triangle of China Liquor", on the southern edge of Sichuan Basin and at the junction of Sichuan, Yunnan and Guizhou provinces. It is an important ecological barrier in the upper reaches of the Yangtze River. The subtropical humid monsoon climate is suitable for the survival of microorganisms and constitutes a unique brewing environment.
Yibin has a unique weak acid yellow mud with strong viscosity, good water absorption and retention, good sealing performance, and is rich in minerals such as phosphorus, iron, nickel and cobalt, which is an excellent natural material for making wine cellars.
Good wine must have good water. The Minjiang River originates from the southern foot of Minshan Mountain and flows through the rainy jungle area. The water and soil along the way are well preserved, clear and transparent all the year round, pollution-free, clear in water quality, sweet in taste, moderate in acid and alkali, and rich in trace elements such as metasilicic acid, strontium and selenium. It is the top grade of wine production.
