Teach you a trick to distinguish between true and false red wine. Many people like drinking red wine. Red wine also has many advantages, not only mellow taste, but also decorative effect. But there are more and more fake red wines on the market. So how to avoid stepping on the pit? Next, I will teach you a trick to distinguish between true and false red wine.
Teach you a trick to distinguish between true and false red wine. 1 For most friends, can you really accept the taste of red wine? In fact, sour, bitter and astringent are the three basic flavors of red wine. We are used to eating mala Tang's tongue, and we can't taste anything fruity, fragrant and woody. No wonder many people in China want to drink red wine with Sprite. Well, whatever it is, as long as it is real wine, I don't care, especially when it comes to fake wine. Nowadays, the wine industry is "deep in water", and some fake wines are packaged in high-end atmosphere, but the cost is only a few dollars a bottle. According to industry veterans, adulteration of fake wine with water is very common, and some fake wines are mixed with water as high as 80% in a single bottle.
The essence of the program is to teach you how to distinguish the authenticity of wine.
The effectiveness of this method has actually reached 99.9%. The most important thing is that this test method is very simple, and what you need is easy to find, that is, edible alkali, which is sold in supermarkets.
Identification method 1
Main ingredients: red wine, edible alkali and water.
Other napkins
operation sequence/order
1, just put a little water in half a spoonful of household edible alkali;
2. Prepare an ordinary napkin;
3. Drop a few drops of red wine on the napkin, and the wine will spread evenly without precipitation in the middle;
4. Drop the edible alkali mixed with water on the red wine;
5. At this moment, something magical happened. If red wine turns dark blue, it is really red wine. If there is no response, then the red wine is fake.
Because red grapes are colored natural anthocyanins, they are purple-red under acidic conditions and blue-green under alkaline conditions, which are also the color characteristics of many natural pigments. If the pigments are mixed, the color will not change.
Identification method 2, suitable for outdoor occasions.
Put a white napkin on the table and drop a few drops of red wine. It will spread evenly. This is the real wine. That's because fake red wine pigment particles are large, which will precipitate in the middle of paper towels, and only water marks will spread outward.
Fake wine on the market is basically pigment blending, so the accuracy of these two methods is almost 99.9%. Then why not 100%? That is, there is another possibility that if fake red wine uses grape skin pigment or other pigments that change color due to different pH values, it will not be detected, but this method is not low in cost and troublesome. So at least we can know that if our red wine is not decolorized with edible alkali, it must be fake, there is no doubt about it.
Teach you a trick to distinguish between true and false red wine II. Judgment method 1
It takes one second to judge whether red wine is true or not. What you need can be easily found in the supermarket, and that is edible alkali.
Main ingredients: red wine, edible alkali and water.
Other napkins
Principle Because real red wine is 100% fermented from grapes, red wine is rich in anthocyanins, while fake red wine is mainly blended with alcohol, saccharin, essence and pigment, without anthocyanins. It is distinguished by the principle that anthocyanins are purplish red under acidic conditions and blue-green under alkaline conditions.
operation sequence/order
(1) Prepare a piece of plain paper.
② Mix half a spoonful of edible alkali into water.
(3) Drop a few drops of red wine on the paper, and the wine will be evenly dispersed without precipitation in the center;
④ Use ② to prepare edible alkali and drop it on the red wine.
At this time, a strange job happened. If red wine turns dark blue, it is really red wine. If there is no response, it is false.
As a result, a small amount of real red wine was poured into alkaline water, and the water in the bowl immediately turned blue-black, and the adulterated red wine also changed color, but the color became lighter, and the scattered water was actually just water marks.
Decision method 2
Drop a few drops of red wine on white paper, if it is evenly dispersed, it is real wine, otherwise it is blended fake red wine. This is because the pigment particles are large and will be deposited in the center of the paper, while only water is dispersed outward.
Real red wine is very uniform in color and basically the same in depth.
Finally, I want to reiterate that the current counterfeiting technology is already very superb. The above methods can only be used to distinguish red wine with a few dollars or more. If it involves passing low-grade wine off as high-grade, or forging the origin and year of the wine label, it is not sufficient.
If it's just a fake brand name of ordinary wine, it's made of alcohol+essence+pigment, which is very low in degree and generally won't do much harm, because if essence and pigment are mixed and drunk too much, the taste is not good, and you won't drink too much. But who thinks they are willing to spend money on fakes, right? Some special and expensive red wine.
