Mian Rou Su Jiu is made using century-old cellar pits and undergoes an ultra-long fermentation period of 180 days, resulting in a "soft" sweetness and richness. After aging in pottery jars for 5 years, the original liquor is then transferred to underground wine cellars lined with pottery panels for another 10 years of storage. The natural aging process of over 15 years harmonizes the body of the liquor, benefiting from the rich functionality, intact microbial system, vigorous metabolic and fermentation capabilities, and abundance of aromatic substances accumulated in the rare ancient cellar pits. Combined with the meticulous craftsmanship of master distillers and the "three-low" process of slow cooking over a gentle flame, it creates the distinguished quality of "Sujiao Green Sujiao." It is rich in a variety of small-molecule substances and health-active compounds, making it more friendly to the human body.
