In China's brewing process, the brewing of baijiu is a complex process that involves a variety of factors, such as the type of raw materials, quality, brewing method, brewing environment, etc. Generally speaking, 100 catties of grain can make about 20-30 catties of liquor.
First, making liquor requires converting the starch in the grain into sugar, which in turn converts sugar into alcohol. This process requires the use of raw materials such as koji, bran, and water, through fermentation, distillation, and other processes. Among them, koji is one of the key raw materials for brewing baijiu, which contains a variety of microorganisms and enzymes that can promote the transformation of starch and sugar.
Secondly, different brewing methods also have an impact on the yield of baijiu. Generally speaking, the yield of solid-state fermentation is low, about 30%; The liquid fermentation method has a higher yield of about 50%. In addition, the brewing environment will also affect the yield of liquor, such as temperature, humidity and other conditions will also have an impact on the transformation of starch and sugar.
To sum up, 100 catties of grain can make about 20-30 catties of liquor, but the specific yield of liquor still needs to consider a variety of factors. In the brewing process, it is necessary to choose high-quality raw materials, suitable brewing methods, and a good brewing environment to make high-quality liquor.
