Wine is a beverage made from fermented grains. China was the first country to make wine. As early as more than 2000 years ago, it invented the brewing technology, and constantly improved and perfected it. Now it has been developed to produce beverages and alcoholic beverages with various concentrations and tastes. Brewing is a process of producing alcoholic beverages with a certain concentration by microbial fermentation. Brewing materials and containers are two prerequisites for grain brewing.
