The koji-making technology of Qingxiaole wine is a national intangible cultural heritage, and the brewing technology is to combine traditional technology with modern technology to make its own patented technology. This 52-degree Qingxiaole is made of five kinds of high-quality grains, namely sorghum, wheat, rice, corn and glutinous rice, plus the unique brewing technology of Qingxiaole wine. This wine is pure and thorough, fragrant, soft and smooth.
Pure grain wine is made from sorghum, corn, soybean and other raw materials by solid-state fermentation. This wine needs to be blended with flavors and fragrances before it can be drunk directly. The fact is, it is not really pure grain wine. Another process is to ferment wheat and wheat Daqu in vats, and distill wine by sand returning technology, which is called real pure grain wine. This wine can be drunk after distillation without any flavors and fragrances.
Method for identify grain wine
Use sodium hydroxide, also known as caustic soda. Put the liquor to be tested in a test tube according to the ratio of 50: 1 caustic soda, or use a cup that we can heat at home at ordinary times, and then boil it in hot water for a few minutes. If it is grain-brewed liquor, the liquor in the test tube will turn yellow. If the color is very light, it means that the pure grain wine is impure and contains alcohol blending ingredients.
Don't change the color of pure alcohol blended wine, because inferior liquor is blended with alcohol and spice sweeteners, and there will be no chemical reaction when it encounters caustic soda. Alcohol blended wine has the characteristics of sore throat, nausea, heartburn, burning sensation, dry mouth, thirst, head injury and so on caused by alcohol problems, while pure grain wine tastes fragrant but not choking, slightly bitter but not astringent and does not choke the throat, does not dry mouth, head injury or discomfort after drinking, wakes up quickly after drunkenness and has little stimulation to human body.
