Method 3 for identifying grain wine

Sodium hydroxide, which is commonly known as caustic soda, is used. Put the liquor to be tested in a test tube at the ratio of 5: 1 caustic soda, or use the cup that can be heated in our usual home, and then add hot water to boil 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 is pure grain wine that is impure and contains alcohol blending ingredients. Do not change color for pure alcohol blending wine, because inferior liquor is blended with alcohol and spice sweeteners, and will not react chemically when encountering caustic soda.

Alcohol blended wine will sting the throat, nausea, heartburn, intense, dry mouth, thirst and head injury due to alcohol problems, while pure grain wine is fragrant but not choking, slightly bitter but not astringent, not choking the throat, not dry mouth, not head injury and uncomfortable after drinking, and will wake up quickly after drunkenness, with little irritation to human body.
