What is the difference between fake and real wine?

Fake liquor has different meanings, there are ordinary liquor with fake famous liquor, mainly the gap between taste and brand, and fake liquor is usedIndustrial alcoholblended, it will endanger human health. The so-called fake liquor is a substance that is mixed with alcohol with chemical reagents, and then imitated, packaged, and sold to the side where it is finally circulated, and becomes the fake liquor that is often referred to in the mouth.

Among them, most of the products used for blending fake wine are methanol.

Acid esters, etc., so the discomfort after drinking fake wine is a phenomenon caused by drinking these chemical agents.

Such as Wuliangye. Fake wine. Prepare a cup, pour a little liquor into the cup, add water, cover the lid and shake it vigorously, shake it a few times to open the lid, look at the color of the wine, if the water inside becomes turbid, it proves that this is a real grain liquor, if the wine is still clear and transparent, it proves that this is a fake liquor mixed with alcohol.

What are the dangers of counterfeit wine?

Methanol is well known to the general public because of its toxicity. Industrial alcohol contains about 4% methanol, which is used by criminals as edible alcohol to make fake wine, and when it is drunk, methanol poisoning will occur. The lethal dose of methanol is about 70 ml.

Methanol has strong toxicity to the human nervous system.

And the blood system has the greatest impact, it passes through the digestive tract, respiratory tract.

or ** ingestion will produce toxic reactions, methanol vapor can damage the mucous membrane and vision of the human respiratory tract.

Symptoms of acute poisoning include: headache, nausea, stomach pain, tiredness, blurred vision, blindness, followed by difficulty breathing, and eventually paralysis of the respiratory center and death. Chronic toxic reactions are: vertigo.

Drowsiness, headache.

Tinnitus, decreased dilificia, digestive disorders.

The difference between fake and real wine is:

1. The bottle type is different.

Many famous brands of liquor have unique bottle shapes. Such as Moutai.

For many years, the milky white cylindrical glass bottle has been used, the bottle body is smooth and free of impurities, and the Luzhou old kiln Tequ uses a colorful bottle, and the bottom of the bottle has the words "Luzhou old kiln winery patent bottle". The bottles of fake wine are of varying shapes and thicknesses, and the outer packaging is old, without freshness, and the sealing is not strict or the teeth are not neatly pressed.

2. The bottle cap is different.

At present, most of the famous liquor announced and recognized by the state in China use aluminum metal anti-counterfeiting covers, which are characterized by smooth lids, uniform shapes, convenient opening, neat and clear patterns and words on the cover, and strict counterparts. If it is counterfeit wine, there will be a dripping phenomenon when it is reversed, the lid is not easy to twist, and the pattern and text are blurred.

3. The degree of turbidity is different.

From the appearance of the glass bottle, the liquor should be absolutely clear and transparent, without sediment, and the clearer and more transparent the better. You can hold the bottle in your hand and slowly turn it upside down, looking at the bottom of the bottle to see if there is any sinking material or cloud-like phenomenon.

As a rule, the hops should be evenly distributed.

The upturn density gap is obvious, and the hops disappear slowly, and the wine is clear and transparent, which is a high-quality wine. If the wine is cloudy, there are floating debris, the hops are densely turned up, unevenly distributed and disappear quickly, it may be a shoddy wine.

4. The fragrance is different.

Before drinking liquor, you can do another identification. One way to do this is to pour a little wine into the palm of your hand, rub it together for a while to heat it up, and then smell it. Generally speaking, if the smell is fragrant, it is a fine wine, if the smell is sweet, it is a medium wine, and if the smell is bitter, it must be a fake and inferior wine.

Another way is to add a drop of cooking oil to the wine.

Looking at the movement of oil in the wine, if the diffusion of the oil in the wine is relatively uniform, and the sinking speed is uniform, the quality of the wine is better, if the oil is in an irregular diffusion state in the wine, the sinking speed changes significantly, you can be sure that the quality of the wine must be problematic, it is a fake and shoddy product.

Fake liquor refers to the famous liquor imitated by small distilleries for sales performance, this kind of fake liquor mainly occurs in large cities or urban areas, and is mixed with industrial alcohol into edible liquor for sale, and industrial alcohol contains methanol, drinking 4 6g will blind people, more than 10g can cause death.

Methods for identifying fake wine:

The first is sensory tasting, which compares and identifies whether the style and quality of the color, aroma and taste of the tested wine sample are typical of the famous wine, or have different degrees; The second is to analyze and compare the physical and chemical composition table, chromatographic analysis chart and sensory comments of the national famous wine standard samples with the tested wine samples one by one, so as to draw authoritative conclusions.

How to identify the authenticity of foreign wine:

1. Look at the logo. According to the requirements of relevant customs regulations, the label of foreign wine must have a Chinese logo and a health inspection and quarantine seal. The Chinese logo can only be obtained after passing multiple certificates and sample spot checks by relevant national departments.

Therefore, foreign wine without Chinese logo and health inspection and quarantine seal may be fake.

2. Identify labels. The genuine label has clear handwriting and good outline; Fake liquor labels are illegible and irregular.

3. Look at the color of the wine. The genuine liquid is golden yellow and translucent; The liquid of the fake wine is dull and has a poor luster.

4. Recognize the anti-counterfeiting cover. The metal security cap on the genuine bottle cap is connected to the bottle cap, while the security cap on the fake wine is glued on. At the same time, the genuine metal anti-counterfeiting cover is tightly worked, the plastic seal is neat and glossy; The fake wine bottle cap is rough in workmanship, the plastic sealing material is not good, it is thick, the gloss is poor, the trademark is blurred, and the three-dimensional sense is poor.

5. Remember the anti-counterfeiting pattern. Wine anti-counterfeiting signs around the country can appear different pattern changes at different angles, and the anti-counterfeiting line can be torn off; The anti-counterfeiting mark of the fake wine is matte, the pattern change is not obvious, and the anti-counterfeiting line is printed.
