Xuan wine is a kind of liquor product. The company's public-private partnership was established in 1951 and was restructured into a joint-stock enterprise in 2004. Anhui Xuanjiu Group Co., Ltd. is located in Xuancheng City, Anhui Province, south of "Jiangnan Shishan" - Jingting Mountain, east of the beautiful and beautiful Shuiyang River. Xuanjiu Park covers an area of ​​more than 910 acres, with more than 7,600 solid-state fermentation small pots, 10 modern packaging production lines, and an annual output of 30,000 tons of white wine. It is currently the largest professional liquor manufacturer in Jiangnan and has entered the ranks of the top 50 Chinese liquor industry. . Mr. Shen Yifang, the leader of the Chinese Liquor Expert Group, served as the General Counsel of Enterprise Quality. Liquor professional technical team has 1 member of national liquor expert group, 3 national liquor judges, 1 Chinese liquor master, 4 national senior brewers, 2 national first-class tasters, national second-class sommelier, provincial Grade liquor judges and winemakers. The product quality was recognized by the Chinese Liquor Expert Group as “Small Xiaomian Mianluo, Jiangnan One Must”, and was rated as “National Geographical Indication Protection Product”, “National Quality Stable Product”, “China Small Brewing Leadership Brand” and “ China's top ten innovative model products, etc. The Xuanjiu Xiaoyan brewing process has been selected as the intangible cultural heritage protection list, and the Xuanjiu Park has been rated as the national 4A level scenic spot. In recent years, Xuanjiu has continued to develop steadily and has been selling well in Anhui for many years, becoming the leading brand of Anhui mid-range liquor. In December 2008, Xuanjiu Xiaoyan Craft was selected as one of the unique brewing techniques and traditional hand-made brewing in the Jiangnan area, and was included in the intangible cultural heritage protection list. In October 2010, Jiangnan Xiaoyan Brewing Technology Research Institute was established. This is the first scientific research institution in the country that specializes in the brewing process of white wine. Shen Yifang is the director of the institute. In 2012, Wang Mingsheng, one of the non-genetic inheritors of Xiaoyan's brewing process, invented the "Technology Improvement of Small Dianchi Cover" technology, and won the 2012 Anhui Province Major Rationalization Suggestion Project and Technology Improvement Achievement Award. In 2013, “Xiaoyu Xuanjiu” passed the provincial local standard and was officially released. At the end of 2014, “Xiaoyu Xuanjiu” became a national geographical indication protection product. Geographical features Xuancheng City is located in the combination of the southeastern mountainous area of ​​Anhui Province and the plain along the Yangtze River. It spans 29°57′~31°19′ north latitude and 117°58′～119°40′ east longitude. Xuancheng City is located in the Yangtze area on the geological section. In the Tai area, the stratum belongs to the lower Yangtze sub-area of ​​the Yangtze stratigraphic zone, and the stratigraphic development of each era is relatively complete. Controlled by geological structures, the terrain is high in the south and low in the north. The landforms are complex and variable, and can be roughly divided into five types: mountains, hills, basins, valleys, plains and plains. The southern mountains, hills and basins are interlaced, and the elevation is generally between 200 and 1000 meters. The central hills and ridges are undulating, and the elevation is generally between 15 and 100 meters. In the north, except for some broken hills, most of them are vast plains. And the star-studded rivers and lakes, the elevation is generally 7 meters to 12 meters, and the climate is subtropical humid monsoon climate type. The monsoon is obvious and the four seasons are distinct. Located in the mid-latitude zone, it is one of the most obvious monsoon climates, with warm springs, hot summers, cool autumns and winter colds. The light and temperature are synchronized, and the rain is hot in the same season. Sunshine and temperature tend to change during the year, and precipitation is concentrated in the warm season. The annual average temperature is 15 °C ~ 16 °C, the annual precipitation is between 1200 mm and 1600 mm, and the annual frost-free period is up to 8 months. Meiyu is an important weather phenomenon in Xuancheng City. Every year, I enter Mei in about mid-June, and in the first ten days of July, the number of days is about 25 days. The average plum rainfall is between 200 mm and 350 mm, accounting for about a quarter of the annual rainfall. The average summer precipitation is 500 mm to 600 mm, accounting for about 40% of the annual precipitation. Due to the complex terrain in the territory, the mountain is relatively large, and the meteorological elements have different distribution types and laws with the slope direction and slope of the mountain, thus forming a three-dimensional climate landscape. Many types of topographical climates and local microclimates are conducive to agricultural diversification. Good mountain, good water, good wine. Xuancheng, the origin of Xuanjiu, is at 30 degrees north latitude. The climate here is characterized by a subtropical humid monsoon climate with an average annual temperature of around 19 °C. The climate is warm and the rainfall is abundant, which is very suitable for wine production. The brewing process of liquor is largely the natural fermentation process of organic matter and the natural growth process of beneficial microorganisms, and a good ecological environment is conducive to the enrichment and reproduction of beneficial microorganisms, which is beneficial to the improvement of wine quality. Xuanjiu is located in the southern poetry of Jiangnan, the southern foot of Jingting Mountain. The clouds in the mountains rise and fall, and it is not scattered all the year round. The geological structure is complex. The soil layer belongs to the red soil conversion zone formed by the hilly and runoff of the south of the Yangtze River. The pH of this soil is The stable acidity of ph6.9 is very conducive to the enrichment of the aroma-producing bacteria such as caproic acid in the ancient Dianchi Lake, and is the root cause of the unique quality of Xuanjiu. The water source used in Xuanjiu Brewing originates from the poetry of Jiangnan-Jingting Mountain and the ancient floodplain on the bank of Shuiyang River. It is rich in high-quality groundwater resources, with clear water, slightly sweet and refreshing, moderate acid and alkali, and low water temperature. The annual temperature is 12.9 ° C, rich in trace elements such as silicic acid, antimony and selenium, which is the best for winemaking.
