Many people like to drink red wine because of its strong nutritional value, so how do you know to identify its authenticity before buying it? The following are the identification techniques of red wine I have compiled for you, hoping to help you.

Identification skills of red wine

Identification method 1

Main ingredients: red wine, edible alkali and water

Other napkins

Operation process

1. Just put a little water in half a spoonful of household edible alkali to open it;

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 time, something magical happened. If red wine turns dark blue, it is real red wine. If there is no reaction, it is fake.

identification method 2 (suitable for outdoor occasions)

put a white napkin on the table, drop a few drops of red wine, and spread it evenly, which is the real wine, because the fake red wine pigment particles are large and will precipitate in the middle of the paper towel, and the outward diffusion is only water marks.

Fake wine in the market is basically pigment blending, so the accuracy of these two methods is almost 99%. So why not 1%? That is, there is another possibility that if fake red wine uses grape skin pigment or other pigments that can change color due to different pH values, it will not be detected, but the cost of this method is not low and troublesome.

So at least we can know that if the red wine in our house doesn't change color when tested with edible alkali, it must be fake, which is beyond doubt. How to identify imported red wine

1. At present, many red wine bottles on the market in China have no trademarks, which are totally products and fakes. Regular imported red wine has the trademark, barcode, address, telephone number and other information issued by the State Administration for Industry and Commerce affixed to the bottle body. Can users download one with their mobile phones? Can I check? Software that can directly scan out its price and related information.

second, look at the formalities: you can ask the dealer to show the hygiene certificate of this batch of wine and the foreign certificate of origin to confirm that the goods and certificates are consistent. For all imported wines that pass the inspection and quarantine, the inspection and quarantine institution will issue a Hygiene Certificate, which covers the detailed information such as the place of origin, year, grape variety, filling date, etc. of this batch of wine, 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 fake inspection and quarantine certificates, the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) launched a new version of the inspection and quarantine certificate on January 1, 21. The new version of the certificate added the feature of anti-copying. The background of the certificate is sky blue and contains hidden features. Under normal circumstances, the hidden features are invisible, but clear ones will appear on the copy? COPY? Words.

third, look at the label: look at whether the bottle label is clearly printed and whether it is copied. According to China's Food Safety Law and Measures for the Administration of Import and Export Food Labels, imported prepackaged foods should have Chinese labels and instructions. The contents of the label should not only be exactly the same as those in foreign languages, but also include the following items: the name of the food, the country or region of origin, the date of production, shelf life, storage guide, the name and address of the manufacturing, packaging, sub-packaging or distribution unit, the name and address of the general distributor in China and other information. This information must be in Chinese black font. If there is no Chinese label and there is a lack of relevant legal label information, the more imported it is, the more likely it is to be fake.

4. Look at the bar code: 69 is filled in China, is American, 3 is French, 7 is Chile, 8 is Spanish and 9 is Australian.

fifth, look at the unit of measurement: take France as an example, its unit of measurement is cl, not ml

sixth, 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 marked as: l7296a611: 58. L7 stands for 27, 296 stands for the 296th filling day from New Year's Day in France, A6 stands for the production line number, and 11: 58 is the exact filling time of that day.

seven, look at the back label: imported red wine is labeled with the original label of the importing country on the front and the Chinese back label on the back.

eight, 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 the sealing role.

nine, look at the wine liquid: look at whether the color of the wine is unnatural, look at whether there is unknown suspended matter on the wine (note: a little precipitation at the bottom of the bottle is normal crystals), and the bad color of the wine has a turbid feeling.

1. wine stopper marking: open the bottle to see if the words on the wooden wine stopper are the same as those on the bottle label.

smell: if the wine has a choking smell like nail polish, it will go bad.

taste: after drinking the first sip of wine, the normal wine is smooth when it passes through the throat, while the problematic wine has a stimulating feeling. After swallowing wine, it is not normal that the smell left in the mouth has a chemical smell or bad smell. Good wine should be refreshing to drink. Common sense of buying imported red wine

1. Look at the bottle of red wine. The bottom of domestic wine bottles is generally smooth, and the bottom of imported wine bottles often has printed patterns and embossed patterns, which is beneficial to heat dissipation during the filling process of red wine. The lower edge of European imported red wine bottles is printed with a sudden code, which corresponds to the characters behind the capacity label, and is used to trace the quality and safety system of wine bottles.

2. Look at the sealing and cork of red wine. Generally, the sealing label of imported red wine can be rotated, because it is the oak stopper that seals the wine, not the sealing label. However, the sealing label of many domestic filled red wines is often tightly made, and it depends on whether the text on the cork stopper is the same as the text on the bottle label.

3. Look at the color of red wine. It can be observed on the background of white walls or white napkins. The color of red wine should be red, purple or pomegranate red, and the wine is ruddy and transparent. Shake the glass a few times and observe the flow of red wine along the glass wall. The slower the decline, the thicker the wine and the better the quality.

4. smell the red wine. Good red wine should have fragrant fruit aroma and mellow wine aroma. Generally, after 1 minutes of sober-up, you can first tilt the glass at the front of your nose and smell its fragrance in a static state, or gently shake the glass, wrap the mouth of the glass around your nose and inhale deeply to smell its fragrance.
