It is believed that many people know that Baijiu is mainly a beverage made from grain.However,with the intensification of market competition,many businesses use industrial alcohol for blending for their own interests,which will cause certain damage to the health of drinkers.In order to buy real grain Baijiu,we can test Baijiu with flake alkali.Next,we will learn about the method of identifying wine with caustic soda.
When testing Baijiu with flake alkali,we can put the flake alkali into Baijiu at a ratio of 50:1.After a period of time,we can check the color of Baijiu to see if there is any color change.We can determine the type of wine based on the depth of its color.If the color is dark yellow,it is Maotai flavor Baijiu;If it is yellow,it is Luzhou flavor Baijiu;If it is light yellow,it is light flavor Baijiu.The three colors mentioned above are generally real Baijiu brewed from grain.
Of course,in the other two cases,the wine will only change color slightly.That could be a mixture of alcohol.If the color of the wine does not change directly after adding caustic soda,it is fake wine mixed with alcohol and water.
In fact,the principle of identifying Baijiu with tablet alkali is very simple.If real wine is brewed from grains,it will definitely react with caustic soda,but fake wine will not.
If you can use this method to identify the authenticity of the Baijiu you bought later,it is also very simple to operate,and the important thing is that the cost is also very low,so it is also a method that people often use.The manufacturer of caustic soda also reminds everyone not to use iron containers to hold wine during operation,as this may affect the identification results.
