Question 1: How to judge the authenticity of red wine with paper towels? In today's society, materialism is rampant, and unscrupulous businessmen are mercenary. In order to make huge profits, they do not hesitate to take risks to manufacture and sell fakes. Among them, the biggest profit of counterfeit goods is alcohol and tobacco, so red wine fraud has become the first of criminals. Here I introduce two ways to identify fake red wine with paper towels: 1. Take two paper towels and overlap them (one is thin and has limited water absorption) or spread a towel on the table. 2. Gently shake the red wine to be identified, then open the cork, pour a little on the paper towel, wait a few seconds, and then observe the traces of red wine wetting on the paper towel. If the red color is uniform and there are no tiny particles, congratulations on this red wine, which is true and safe to drink, because the real red wine is made of grapes, and its red color is a natural pigment in grapes. It must be uniform in the wine, and the color left on the paper towel must be uniform, and there can be no small particles. If the color on the paper towel is uneven or different shades, and some even have red spots distributed on it, congratulations, this bottle of wine has been identified as fake by you. Because fake red wine is blended with synthetic pigments, counterfeiters can't accurately grasp the saturation of pigment molecules dissolved in liquid, and there will always be insufficient dissolution (unsaturated solutions rarely appear, so the color of fake wine can't reach the visual effect), so the traces left on paper towels will be uneven in color and there will be tiny particles! However, although napkins are very convenient to distinguish the authenticity of red wine, it is better to know more about wine and use your own experience to identify it more accurately. There are two kinds of fake wine, one is blended wine with little or no grape juice, and the other is shoddy wine, posing as famous brand wine. The above methods can help you identify fake wine that is harmful to your health. As an alcoholic beverage, wine must be marked with product name, ingredient list, net content, pure fruit juice content, alcohol content, factory name, address, production date, shelf life and other contents in accordance with relevant state regulations. If the label of a bottle of wine is incomplete, or the date of production, factory name and address are not marked, it may be a fake and shoddy product. Secondly, from the appearance, the wine should be clear and transparent, without sediment and turbidity, otherwise it may be fake and shoddy.

Question 2: How to identify red wine with paper towels? Spread two paper towels on the table, and use two straws to drop the real wine and the blended fake ordinary wine on the paper towels respectively. The wine dripped on the paper towel and quickly dispersed. Among them, the real wine drops on the paper and spreads evenly. After the blended fake wine drips on the paper towel, the surrounding color is lighter and the middle color is darker, and the pigment accumulates on the paper like a blood clot.

This is because the red color in real wine is a natural pigment with small particles. The wet trace spread on the paper towel is even wine red, and there is no obvious water trace diffusion. The blended fake wine is blended with chemical synthetic pigment, and the pigment particles are large and will be deposited in the middle of the paper towel, while the water trace continues to spread outward, and the boundary between the red * * * domain and the water trace is obvious.

Question 3: How to identify true and false red wine with paper towels, and how to identify true and false red wine with paper towels as ordinary consumers? Red wine professionals said that red wine, as a kind of wine, must indicate the product name, ingredient list, net content, pure juice content, alcohol content, factory name, site, production date, shelf life and other contents on the bottle label in accordance with relevant national regulations. If the label of a bottle of red wine is incomplete, or the date of production, factory name and address are not marked, it is a fake and shoddy product. Secondly, from the color point of view, if the wine is clear and transparent, without precipitation and turbidity, it is good wine; On the contrary, it is fake and shoddy red wine. Relevant people told me that there is also a simple way to identify true and false red wine. Take a good quality napkin and pour the red wine on it. The red color in the original red wine is a natural pigment with very small particles. The wet stain spread on the napkin is the red color of unified red wine, and there is generally no water stain to spread. Because fake red wine is blended with chemical synthetic pigments such as inkstone red, its pigment particles are relatively large, which will generally precipitate on napkins, and at the same time, there will be water traces spreading outward.

Question 4: Hello, my wine is dry red. Listen to other people's paper towel identification method, I also tried it myself. The paper towel test you mentioned is a method to distinguish between true and false wine: drop a drop of wine on a clean paper towel, and the red color of real wine will spread evenly, while the red color of fake wine will gather in the center and water marks will appear on the periphery. But this method is only applicable to fake wine mixed with pigment. It is not suitable for all inferior wines. Quality should be evaluated from color, fragrance and taste. The wine labels produced by regular wine manufacturers all indicate the name, manufacturer, net content, alcohol content, production date and many other information. Secondly, carefully observe the wine body: the real wine body is clear and bright, unless the old wine is aged, there will be no sediment or dregs, the fake wine body is dim, and some wines still contain sediment. Third, smell the wine: real wine is fruity, floral or aged, rich and comfortable, while fake wine often smells like nail polish or essence.

Question 5: the red wine bought at home is true and false with paper towels. How to try? Take a napkin of better quality and pour the red wine on the napkin. The red color in the original red wine is a natural pigment with very small particles. The wet stain spread on the napkin is the red color of unified red wine, and there is generally no water stain to spread. Because fake red wine is blended with chemical synthetic pigments such as inkstone red, its pigment particles are relatively large, which will generally precipitate on napkins, and at the same time, there will be water traces spreading outward.

Question 6: This is a photo of me testing red wine with a paper towel. The wine is evenly distributed around, which is probably true. You can also add edible alkali to see if it changes color. If it changes, it's true.

Also, you'd better look at the wine label, because some wines are brands of domestic manufacturers, and the wine is real, but the quality is average.

Question 7: How can you tell the quality of red wine when you pour it on a paper towel? Red wine poured on a tissue can't tell the good from the bad. More than a decade ago, there was red wine blended with three essences and one water in China, and it was true and false with paper towels.

In today's China, there is no red wine blended with three essences and one water, so it is invalid to look at the authenticity of paper towels. Since the bottle is opened, drink it, and judge the quality from balance, richness, complexity and aftertaste.

Question 8: Is it reliable to identify red wine with paper towels? How to identify red wine with paper towels?

Fold the white napkin on the table, drop a few drops of red wine, and smear it evenly to get the real red wine; If there is precipitation in the middle of the paper towel, it is that the fake red wine has dispersed water.

The principle of distinguishing red wine from real wine with paper towels;

Because fake red wine is mostly blended with alcohol, saccharin and essence pigment, the pigment particles are larger. When poured on paper, the pigment particles will be deposited in the middle of the paper towel, and only the water traces will be diffused outward.

Although this detection method is simple and easy, it is not scientific enough, because the texture of paper towels is different, which also has a certain impact on the diffusion of liquid.

Question 9: How to tell 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, or 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 10: Two kinds of red wine are better when poured on paper towels. Besides this method, what other methods can identify the score of 10? I have never seen or learned this method. The most common method is to look at the hanging cup, pour the good wine into it and shake it gently to make the wine circulate evenly on the wall of the cup. When shaking stops, the wine will form a liquid column. Slowly flowing downwards, the thicker the wine, the longer it lasts. It is generally believed that the wine has a high body and quality. Of course, these methods are not absolute. Personally, for ordinary people, what suits their taste is the best. If it is a local tyrant, it is another matter.
