Identification method of pure grain liquor

At present, liquor on the market can be divided into two categories, one is pure grain liquor made from sorghum, corn, soybeans and other raw materials by solid state fermentation, and the other is liquor blended with alcohol and essence. The contents of manganese, lead and methanol in pure grain liquor are extremely low, and the harmful components to human body can be ignored, while the blended liquor is very harmful to human body. So how to identify whether the liquor brand you buy is pure grain liquor or blended liquor? Here are three identification methods, which I hope are useful. Method 1: \x0d\ Liquor brewed from real traditional grain is fragrant but not choking, slightly bitter but not astringent. The aroma of grain, wine and wine is obvious, which is obviously different from that of alcohol blended wine. Pure grain wine smells pure and full, while liquor blended with alcohol smells stiff. Daquanyuan Liquor, Northeast Famous Liquor, Pure Grain Brewed Liquor. Soft taste, no dry mouth, throat choking, headache or discomfort after drinking. \x0d\x0d\ Method 2 for identifying pure grain liquor: \ x0d \ Put a drop of liquor in the palm of your hand, then cross your hands to make them touch each other and rub them hard for a few times, so that the fragrance of pure grain liquor will be fragrant and lasting after heating; The liquor blended with alcohol has only the flavor of essence, which not only smells strange, but also stays for a short time and soon loses its flavor. Daquanyuan wine detected by this method is really pure grain wine. \x0d\x0d\ Method 3 for identifying pure grain wine: \ x0d \ Use sodium hydroxide, also known as caustic soda. Put the liquor to be tested and caustic soda in a test tube at a ratio of 50: 1, 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. It is pure blended wine, and there is no discoloration, because the blended wine will not react chemically when it meets caustic soda.
