What do you think of red wine?

Question 1: How to tell the true and false red wine 1? Blending wine with alkaline noodles.

First, prepare alkaline noodles, white vinegar, four transparent cups and a small spoon.

Next, the experiment officially began. There are four transparent cups. The two cups on the left are filled with real red wine, and the two cups on the right are filled with blended fake wine. Generally, white wine blended with wine is thin and transparent, and smells fresh and sweet; Real red wine is slightly sticky and transparent, but the transparency is slightly lower and the smell is a little sour.

Then, take half a spoonful of alkaline noodles with a small spoon, put them into a glass of Zhen Hong wine and stir them evenly, and then put the same amount of alkaline noodles into another glass of blended wine and stir them. After about half a minute, the contrast of the four glasses changed obviously: one of the two kinds of Zhen Hong wines with alkaline surface obviously turned blue-black, even almost completely black, and the light transmittance of the wine was almost zero, which was no longer transparent even in the sun, which was very different from the glass without alkaline surface; However, the color and transparency of the two blended wines have not changed, and the ones with and without alkali noodles are exactly the same.

After the white vinegar test, the real body is shaped. Half a spoonful of alkaline noodles, fake wine exposure, this process is really amazing. However, the experiment is not over. Alkaline noodles only make fake wine appear, and the final determination of the identity of real wine needs another protagonist, that is white vinegar.

Pour white vinegar into a small spoon, add a spoonful to each of the two cups that have just been put into the alkaline surface, and after stirring evenly, it will turn into blue-black wine when it meets the alkaline surface, and immediately restore the original purplish red and the previous transparency, while the blended fake wine remains unchanged.

The amount of white vinegar should be at least equal to or slightly more than that of alkali powder, otherwise the color reduction effect may be affected.

Through this step, it can be completely confirmed that the real wine, that is, 100% grape juice, changed color twice before and after, while the blended fake wine never changed color.

Experimental principle of alkaline surface method

Anthocyanin exists in the peel of grapes, which will react with alkali, and the original purple will become purple-black and blue-black. According to the national standard, the real wine must be 100% grape juice, and the grape juice must contain anthocyanins. Therefore, if it changes color in case of alkali, it means that the wine is true.

Fake wine is generally blended with amaranth, carmine, caramel, essence, alcohol and sodium cyclamate. There is no grape juice in the blended wine, and the color is exchanged with pigment, which will not react with alkali, so it will not change color.

However, after adding white vinegar, the anthocyanins that reacted with alkali reacted with acid and changed back to the original purple color, which further confirmed that this wine is really a wine with a grape juice content of 100%.

Second, the paper towel method

What should I do if I order wine at the hotel and don't have soda noodles on hand? There is also a simpler method-"paper towel detection method" to identify the authenticity of wine.

Take the paper towel and drop the wine on it. Because the red color in the puree wine is a natural pigment, the particles are very small, so the wet trace spread on the paper towel is the red color of the uniform wine, and there is no obvious water trace diffusion. Fake wine is blended with chemical synthetic pigments such as amaranth red, and the pigment particles are large, which will be deposited in the middle of napkins, while the water trace will continue to spread outward, and the boundary between the red * * * domain and the water trace is obvious, so it is easy to distinguish between true and false wine.

Although this detection method is simple and easy, it should also be judged according to the quality of paper towels, and the texture of paper towels also has a certain influence on the diffusion of liquid.

Question 2: How can red wine tell the truth from the false? Imported red wine will have an international bar code on the back, and the first number of the bar code represents the country. For example, 0 is the source of American articles: China Wine Merchants Network, 3 is French, 7 is Chile, 8 is Spanish and 9 is Australian.

Look at the price The lowest price of red wine that meets the drinking standard should also be in 60 yuan ~ 70 yuan.

Look at the bottom of the bottle. In order to facilitate storage, real red wine usually has a deep depression at the bottom of the bottle. If the depression is too shallow, it means that this red wine is probably fake.

Look at the level Usually, red wine has three grades: A, O and C, and those who reach these three grades are authentic.

Fifth, look at the unit of measurement. The capacity of imported red wine on the label is 75cl instead of 750ml, and "cl" is deciliter. If it is labeled as "ml" (milliliter), it is counterfeit imported red wine.

Sixth, look at the tightness of the wine seal. The wine seal on the wine stopper of genuine red wine can be rotated, because it is actually the cork that plays a sealing role. And some fake and shoddy brewers, worried that the wine plug would leak if it was not sealed well, sealed the wine.

Question 3: How can the wine on the market tell the truth from the false? Step one, look at the appearance of the bottle? See if the bottle label is clearly printed? Is it fake or copied? ? See if there is anything wrong with the bottle cap. Is there any sign of being opened? ? See if the international bar code on the label on the back of the bottle starts with three words: the French international code is 3. ? See if there is a Chinese logo on the label on the back of the bottle: according to Chinese laws, all imported food must be labeled in Chinese. If there is no Chinese label, it may be smuggled and imported, and the quality cannot be guaranteed. Step two, look at the wine? See if the color of wine is unnatural? ? See if there is any unknown suspended matter on the wine. (Note: A little precipitation at the bottom of the bottle is a normal crystal)? When the wine goes bad, the color becomes cloudy. Step three, look at the wine stopper logo? Open the bottle and see if the words on the wooden wine stopper are the same as those on the bottle label. In France, wine bottles and wine stoppers are special. Step four, smell the wine? If wine smells like nail polish, it will go bad. Step five, wine tasting? After drinking the first sip of wine, when the wine passes through the throat, the normal wine is smooth, while the problem wine has a sense of * * *. ? It is not normal for the smell left in the mouth to have a chemical smell or a foul smell after swallowing wine. ? Good wine should be refreshing to drink.

Question 4: How to tell the true and false red wine apart from what they said above, the real imported wine should be a little astringent. After a while, there will be some sediment at the bottom of the bottle. After opening the bottle, you can pour a little into the red wine glass, and then gently shake the glass to see the suspension of the wine.

Adopt it

Question 5: How to identify the authenticity of red wine? Method for identify that authenticity of red wine:

1. See the procedure.

The distributor may be required to show the health certificate and foreign certificate of origin of the wine to confirm the conformity of the goods certificate. For all imported wines that pass the inspection and quarantine, the inspection and quarantine institutions will issue health certificates, which include detailed information such as origin, year, grape variety and filling date. , so that consumers can distinguish whether the wine meets the relevant hygiene standards and whether it is legally imported food. In order to prevent illegal personnel from forging false inspection and quarantine certificates, AQSIQ has started to use a new version of the inspection and quarantine certificate since 20 10 1, and the new version of the certificate has added a copy prevention function. The background of the certificate is sky blue and contains hidden features. In general, the hidden features are invisible, but the word "copy" will clearly appear on the copy.

Look at the label

See if the bottle label is printed clearly and copied. According to China's "Food Safety Law" and "Measures for the Administration of Import and Export Food Labels", there should be Chinese labels and instructions for importing into prepackaged foods. The contents of the label should not only be completely consistent with the foreign language, but also include the following items: food name, country or region of origin, production date, shelf life, storage guide, name and address of production, packaging, sub-packaging or distribution unit, name and address of general distributor in China, etc. This information must be in Chinese black font. If there is no Chinese label and the relevant legal label information is lacking, the more imported it is, the more likely it is to be fake.

Look at the bar code

69 for China, 0 for USA, 3 for France, 7 for Chile, 8 for Spain and 9 for Australia.

4. Look at the unit of measurement

For example, in France, the unit of measurement is cl, not ml.

5. Look at the date of production

The method of marking the production date of imported red wine is very special. For example, French red wine is generally labeled as l7296a0611:58+0: 58. L7 stands for 2007, 296 stands for the 296th filling day since New Year's Day in France, A06 stands for the production line number, and 1 1: 58 is the exact filling time of that day.

6. Look at the label at the back

Imported red wine is marked with the original label of the word importing country on the front and the Chinese back label on the back.

7. Look at the tightness of the wine seal

The wine seal on the original imported red wine bottle stopper can be rotated, because it is actually the cork that seals.

8. Look at the wine

See if the color of the wine is unnatural, and see if there is unknown suspended matter on the wine (note: a little precipitate at the bottom of the bottle is normal crystal). The color of the deteriorated wine has a turbid feeling.

9. Wine bottle stopper identification

Open the bottle and see if the words on the wooden wine stopper are the same as those on the bottle label.

10. odor

If wine smells like nail polish, it will go bad.

1 1.

After drinking the first sip of wine, when the wine passes through the throat, the normal wine is smooth, while the problem wine has a sense of * * *. After swallowing wine, the smell left in the mouth is chemical or smelly, which is abnormal. Good wine should be refreshing to drink.

Question 6: How to identify the authenticity of red wine? Hong Kong Famous Wine Club will share some tips on online shopping to identify true and false red wine.

1) Look at the comments of members before buying. Order your favorite wine, no matter how many pages of comments there are. Only in this way can you know whether this bottle of wine meets the requirements you want.

2) You can look at the bar code of red wine before placing an order. Most of the wine purchased online is imported red wine, and all imported goods are required to have Chinese labels. You can carefully check whether there is a Chinese logo on the back of the red wine. In addition, it can also be judged by bar code. If it starts with 6, it is made in China; If it starts with 3, it is made in France; If it starts with 9, it's made in Australia.

3) Many sommeliers put their thumbs on the bottom of the bottle when pouring wine. This is because the thumb is the lowest temperature part of the human body, so it will not affect the flavor of the wine itself. Therefore, when receiving goods, pay attention to carefully observe the bottom of the bottle to see if there are red wine fingers.

4) As we all know, wine stoppers can convey a lot of knowledge to us. So try to open the wine seal on the wine plug when harvesting. If it can rotate, it means that this bottle of wine is true; If it can't rotate, it means it is a fake bottle of wine. This is because the wine seal printed with the brand logo is only an identification symbol, not for sealing. But some fake wineries are afraid of air leakage, so the wine is tightly sealed. As long as you master the common sense of online shopping for red wine at the above four points, it is not difficult to buy a bottle of red wine you like.

Question 7: How to distinguish the authenticity of wine With the increasing domestic consumption level, imported wine has become a "frequent visitor" on the table of the people. 20 1 1 year, China people consume/kloc-0.9 billion bottles of wine, which has surpassed Britain to become the fifth largest wine consumer and the eighth largest importer in the world. 20 1 1, 7914,300 liters of wine were imported from Ningbo Free Trade Zone, amounting to 36.66 million US dollars, which were 20 1 growth 137.9% and 25 1.6% respectively, showing a blowout state. The consumption of imported red wine is increasing year by year, but there are also many fake and shoddy wines in the market, such as pigment blending, forgery of origin, shoddy and so on. On the occasion of Consumer Rights Protection Day, the staff of Ningbo Yinzhou Inspection and Quarantine Bureau provided consumers with suggestions on how to identify genuine and fake imported red wine to help them safeguard their legitimate rights and interests.

Steps/methods

1 Look at the formalities: you can ask the dealer to show the hygiene certificate and foreign certificate of origin of this batch of wine to confirm that the goods and certificates are consistent. For all imported wines that pass the inspection and quarantine, the inspection and quarantine institutions will issue health certificates, which include detailed information such as origin, year, grape variety and filling date. , so that consumers can distinguish whether the wine meets the relevant hygiene standards and whether it is legally imported food. In order to prevent illegal personnel from forging false inspection and quarantine certificates, AQSIQ has started to use a new version of the inspection and quarantine certificate since 20 10 1, and the new version of the certificate has added a copy prevention function. The background of the certificate is sky blue and contains hidden features. In general, the hidden features are invisible, but the word "copy" will clearly appear on the copy.

2 look at the label: see if the label of the bottle is clearly printed and plagiarized. According to China's "Food Safety Law" and "Measures for the Administration of Import and Export Food Labels", there should be Chinese labels and instructions for importing into prepackaged foods. The contents of the label should not only be completely consistent with the foreign language, but also include the following items: food name, country or region of origin, production date, shelf life, storage guide, name and address of production, packaging, sub-packaging or distribution unit, name and address of general distributor in China, etc. This information must be in Chinese black font. If there is no Chinese label and the relevant legal label information is lacking, the more imported it is, the more likely it is to be fake.

3 Look at the barcode: 69 for China, 0 for the United States, 3 for France, 7 for Chile, 8 for Spain and 9 for Australia.

4 Look at the unit of measurement: Take France as an example, its unit of measurement is cl, not ml.

5 look at the date of production: the method of marking the date of production of imported red wine is very special. For example, French red wine is generally labeled as: l7296a0611:58+0: 58. L7 stands for 2007, 296 stands for the 296th filling day since New Year's Day in France, A06 stands for the production line number, and 1 1: 58 is the exact filling time of that day.

6 Look at the back label: the imported red wine has the original label with the words of importing country on the front and the Chinese back label on the back.

7 Look at the tightness of the wine seal: the wine seal on the original imported red wine wine stopper can be rotated, because it is actually the cork that plays a sealing role.

8 Look at the wine liquid: Look at whether the color of the wine is unnatural or not, and see if there is unknown suspended matter on the wine liquid (note: a little precipitate at the bottom of the bottle is normal crystal). The color of the deteriorated wine has a turbid feeling.

9 wine stopper marking: open the bottle to see if the text on the wooden wine stopper is consistent with the text on the bottle label.

10 smell: If the wine has a choking smell similar to nail polish, it will go bad.

1 1 Taste: After drinking the first sip of wine, when the wine passes through the throat, the normal wine is smooth, while the problem wine has a sense of * * *. After swallowing wine, the smell left in the mouth is chemical or smelly, which is abnormal. Good wine should be refreshing to drink.

Matters needing attention

In addition, there are some simple self-test methods.

Alkaline method: According to the national standard, real wine must be brewed with 100% grape juice, which must contain anthocyanins. Anthocyanin will react with alkali, and the original purple will become purple-black and blue-black. So if the color of red wine changes after adding edible alkali (commonly known as soda, used for bread fermentation, etc.). ), indicating that the wine is true. Fake wine is generally blended with amaranth, carmine, caramel, essence, alcohol and sodium cyclamate. There is no grape juice in the blended wine, and the color is blended with pigment, which will not react with alkali, so it will not change color.

Question 8: How to tell the authenticity of red wine? The first step is to identify the authenticity of the original bottle of imported wine (red wine exchange). Look at the appearance of the bottle. Look at the label information: Generally speaking, foreign wine bottles are thicker than domestic ones, and the bottle position generally has the words 75cl and batch number, but there is nothing at home, or 750ml and the manufacturer! See if the bottle label is clearly printed? Is it fake or copied? See if there is anything wrong with the bottle cap. Is there any sign of being opened? Third, see if the international bar code on the label on the back of the bottle is the bar code of the importing country. For example, the French international code is 3: According to the laws of China, all imported foods must be labeled in Chinese. If there is no Chinese label, it may be smuggled and imported, and the quality cannot be guaranteed. The second step is to look at the wine to see if the color of the wine is unnatural. See if there is any unknown suspended matter on the wine. (Note: a little precipitate at the bottom of the bottle is normal crystal) The color of the wine is turbid when it goes bad. Step 3: Look at the logo of the wine stopper and open the bottle to see if the text on the wooden wine stopper is the same as the text on the bottle label. In France, wine bottles and wine stoppers are special. Step four, smell the wine. If wine has a choking smell like nail polish, it will go bad. The fifth step is to taste the wine and take the first sip. The wine has passed through the throat, the normal wine is smooth, and the problem wine has a sense of * * *. It is not normal for the smell left in the mouth to have a chemical smell or a foul smell after swallowing wine. Good wine should be refreshing to drink. Note: All imported red wine will have a certificate of origin, and it can be seen from the documents whether it is imported or not. If you can see these documents, it will be very secure. (Hong Jiu Hui&; Excerpt: u.hongjiuhui/space-7-do-blog-id-16 Wine Exchange-Online Shopping Mall for Imported Wine (Red Wine Exchange) This is the gathering place of old and new world wines such as French red wine and Australian red wine, and it is the first choice for group buying, wholesale and gathering of red wine.

Remember to adopt

Question 9: How to tell the authenticity of imported wine? 1, wine label.

Generally speaking, if it is an original bottle of imported wine, you can know its information from the wine label. According to the customs regulations, imported wine needs to be labeled with the original text of the importing country on the front of the bottle, and the official Chinese back label is also needed on the back.

Step 2 show up

The capacity of imported French wine on the wine label is usually 75clE, not 750 ml commonly used in China. The date of the original imported wine bottle is also different from that in China. For example, the date marking method of French wine is L7296a06 1 1:58+0: 58, where L7 stands for 2007, 296 stands for the 296th day of French New Year filling, and A06 stands for the production line number.11:58 is accurate.

3. Barcode

The back of the original imported wine bottle will be marked with an international bar code with 13 digits, in which 1~3 digits are country codes; The 4th to 8th digits are the manufacturer's code; The number 9~ 12 is the manufacturer's internal commodity code; 13 is the check code.

The first number of the bar code represents different countries, such as 0 is the United States, 30~37 is French, 6 is China, 7 is Chile, 8 is Spanish, 9 is Australia and so on.

4, wine seal

Generally, the wine seal with the brand logo printed on the wine stopper of the original bottle can be rotated. Because the sealing performance of the wine stopper is good, the wine seal is only a symbol of the brand logo, so it can be rotated without sealing. However, some fake or imitation wines in China are worried about the poor sealing performance of wine plugs, so they also seal the wine together, leaving a flaw instead.

5. Umbilical plum clothing

Generally speaking, the words on the cork will be consistent with the contents on the wine label, such as the name of the winery and the production batch number. However, the details of domestic bottled wine are difficult to make and consumers need to distinguish carefully.

In fact, there are many skills, so I won't list them here. If you are interested, you can have a look at the imported wines of Haiwei Fenjiu, all in the original bottles. Friends who want to operate can also find their teacher Duan. This brand-new model is different from traditional trade and has broad prospects. I hope to adopt.

Question 10: How to tell the authenticity of red wine? Look at the barcode. Imported red wine will have an international bar code on the back, and the first number of the bar code represents the country. For example, 0 is the source of American articles: China Wine Merchants Network, 3 is French, 7 is Chile, 8 is Spanish and 9 is Australian.

Look at the price The lowest price of red wine that meets the drinking standard should also be in 60 yuan ~ 70 yuan.

Look at the bottom of the bottle. In order to facilitate storage, real red wine usually has a deep depression at the bottom of the bottle. If the depression is too shallow, it means that this red wine is probably fake.

Look at the level Usually, red wine has three grades: A, O and C, and those who reach these three grades are authentic.

Fifth, look at the unit of measurement. The capacity of imported red wine on the label is 75cl instead of 750ml, and "cl" is deciliter. If it is labeled as "ml" (milliliter), it is counterfeit imported red wine.

Sixth, look at the tightness of the wine seal. The wine seal on the wine stopper of genuine red wine can be rotated, because it is actually the cork that plays a sealing role. And some fake and shoddy brewers, worried that the wine plug would leak if it was not sealed well, sealed the wine.
