Now a huge number of people are poisoned by low-quality alcohol, and this happens not only in our country, but also abroad. Indeed, often a violation of the vodka preparation process leads to an increase in the content of fusel oils, methyl alcohol and furfural in it. When buying vodka in a store, doubts about the quality of the product often arise. However, there are currently many ways to determine the quality of the drink that will help protect you from poisoning.
It is necessary
- - sulfuric acid;
- - litmus paper;
- - matches;
- - glass.
Instructions
Step 1
Pour 30-50 grams of vodka into a glass, add exactly the same amount of sulfuric acid. If the mixture has turned black, then the vodka is dangerous to your health, it must be poured out immediately.
Step 2
Some counterfeiters add sulfuric acid to weak vodka to increase the strength of the drink. To determine the quality of vodka, you need a litmus test. Pour a small amount of suspicious vodka into a glass and dip the litmus paper into it. If the piece of paper turns red, you should not drink this vodka, as it contains a large amount of acids that are dangerous to your health.
Step 3
Carefully pour the vodka into the bottle cap and light it. A good 40-degree vodka will burn with a blue flame. If the vodka does not burn or, on the contrary, flashes like gasoline, you should think about it. It is better not to drink such vodka.
Step 4
When buying a bottle of vodka, shake it up. If the bubbles are large, then the vodka is highly diluted with water. If small bubbles rise upward like a snake, this indicates a good quality of vodka.
Step 5
Having opened a bottle of vodka, try to breathe it in, as they say, deeply. If you feel a sharp unpleasant and not vodka smell, it is better to refuse such vodka. Perhaps the vodka has an admixture of acetone or is made from industrial alcohol. Therefore, it is better not to risk your health.
Step 6
There is another old way to check the quality of vodka. Take a bottle of vodka and try freezing it at -20 degrees. If even small pieces of ice have formed in the bottle, this indicates that it has been diluted with water. Of course, it is better not to use such vodka.
