To brew perfect strong aroma Baijiu, what has the world done? Luzhou, the Baijiu City of China
Luzhou, the Baijiu City of China and the south gate of Sichuan Province is located at the junction among Sichuan Province, Yunnan Province, Guizhou Province and Chongqing municipality and it is one of the three cores of the China’s Baijiu golden delta (Luzhou, Yibin and Renhuai). With four distinct seasons and moderate climate, Luzhou has the most suitable warmth and moisture, which are two important elements in brewing Baijiu. After investigating Luzhou, the UNFAO praised: “As a city spanning the Yangtze River and located at north latitude 28°, Luzhou is the best place for brewing high-quality Baijiu.” Also, the Chinese and foreign experts both concluded that only with the unique and unduplicated geographic conditions, like the climate, soil, water resource and raw materials, microorganisms and Baijiu-making techniques, can Luzhou make this protected eco-origin product with legendary quality.
Sunlight
Luzhou has abundant annual rainfall, and lies in the river valley and among mountains. It’s good for the growth of the microbes.
Wind speed
Located at the southern margin of Sichuan basin, Luzhou is protected by the Tibet plateau, Qinba ridge and Yunnan-Guizhou plateau. There has few strong wind throughout the year. Here is the region with the smallest wind speed among the country’ s Baijiu-making areas.
Humidity
Luzhou’s abundant annual rainfall and humid air all the year round thanks to its location in a river valley and among mountains foster favourable air humidity for the growth of Baijiu-making microbes.
Temperature
Luzhou has a subtropical humid climate. It has high temperature, ample sunshine and four seasons, which are all good for the growth of microorganisms and making the best Baijiu under such a suitable tem- perature.
Altitude
Baijiu- producing areas in Luzhou are mostly located at the southern margin of hilly regions of Sichuan basin, and most of them are 200 to700 meters above the sea level. It’s suitable for the growth of microbes, Nuohong raw material sorghum and other crops for Baijiu brewing.
Soil
Sichuan River in the upper reaches of Yangtze River flows through Luzhou, and Jurassic and Cretaceous purple soil with rich nutrients, moderate PH value, good water retention is good for growing sorghum, wheat and other crops which are the main materials for Baijiu production . The purple soil can also purify water and turn it into spring water after being filtered layer by layer for Baijiu brewing. (Source: Official website of Luzhou Laojiao)
