Shen Yan, a master of modern brewing engineering, travels to Cheng Yingzhou and is the son of a run-down brewery. Faced with a desperate situation where his family is poor and his grandmother is seriously ill, he uses modern knowledge to break the situation: first using a simple distillation device to improve home brewing, and making it "scarlet as red as pills" The high-quality red yeast wine opened up the market, slapping the relatives who coveted the family's best products; they then used the river dredging project to introduce hydraulic winemaking equipment to solve the problem of mass production, and at the same time planted improved glutinous rice and grapes to build a raw material supply chain; later, they established a winemaking workshop with refugees, invented the distiller's yeast purification technology to reduce costs, and even used wine as a medium to make friends with border generals and seize business opportunities in the Song and Liao mutual trade. From a private brewer who avoided being investigated by officials, to a tycoon who obtained a brewing license from the imperial court, Shen Yan prospered the country with wine and built an industrial foundation in troubled times.
