For that aromatic baijiu, what the world has done to you?
Luzhou, the Baijiu City of China，
is a part of Sichuan Province and located at the junction among Sichuan province, Yunnan Province, Guizhou province and Chongqing municipality.With four distinct seasons and moderate climate, it is a core hinterland of China’s baijiu golden delta. 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 making pure-quality distilled baijiu.” The Chinese and foreign experts both concluded that only due to the unique and unduplicated geology, climate, soil, water resource, raw materials, microorganisms and baijiu-making techniques, can Luzhou make this protected eco-origin product with legendary quality, saying,
“Without the exceptional geographical environment consisting of the water, soil, air and microorganisms in Luzhou, there will be no Luzhou Laojiao”.
Core hinterland of the Golden Triangle of Chinese Liquor
Best for making high quality, pure distilled spirits.
Both sides of the Yangtze River
Luzhou City is a subtropical humid climate with an average annual rainfall of 1200 mm, abundant water, and is surrounded by river valleys and mountains. There is less sunshine, less evaporation, and the air is moist all year round. The monthly relative humidity is 75-87 %, and the average annual relative humidity. Up to 82 %, It is nearly 30 inches higher than North China and 15 inches higher than Jianghuai production area, creating a very favorable air humidity condition for microbial growth.
The average monthly sunshine hours in the main production area of Jichuan is only 58-65 hours. It is dense and dense all day long. The sultry and humid rain and fog environment is very favorable for the fermentation and ripening of wine.
Luzhou City is a subtropical humid climate zone with high temperatures, abundant sunshine, abundant rainfall, and four distinct seasons. The average annual temperature is 17.5 to 18.0 °C. The change between years is 16.8 to 18.6 °C, and the difference between high and low years is 1.8 °C. Especially conducive to microbial growth, It has the temperature condition of making high quality liquor.
Luzhou City is located on the southern edge of the Sichuan Basin. There are few strong winds throughout the year, mostly breezes within 2 meters per second. It is one of the regions with the smallest wind speeds in the wine producing areas of the country.
For every 1000 metres elevation, the temperature decreases by 6 degrees Celsius. Luzhou wine belt is mostly distributed in the northern shallow hills and wide valleys. The area is an extension of the parallel fold zone in eastern Sichuan, which belongs to the southern margin of hilly area in Sichuan Basin. The altitude of the area is more than 200-700 meters. It is very conducive to the growth of microorganisms and raw materials crops such as sorghum.

Luzhou is located in the north and south of Sichuan River in the upper reaches of the Yangtze River. The soil is Jurassic and Cretaceous purple soil with moderate acidity and alkali. The soil in hilly areas and riverbanks has good water retention. There will be no water shortage and aging in pits in the north. This provides a good fermentation container for liquor production.
Soil is rich in nutrients, including paddy soil, new accumulated soil, purple soil and other six categories of high-quality soil, very suitable for planting sorghum, wheat and other crops, these are the main raw materials for liquor-making.
Purple soil is beneficial to water purification. Purple soil is widely developed. This kind of soil is generally about 50 centimeters thick, with high content of gravel and sandy soil and good water permeability. When groundwater and surface water pass through red soil layer, many trace elements beneficial to human body are dissolved and filtered through layer by layer to form clear spring water.
