recently, the lady of the city told the city girl that she felt sweet when she bought the bulk red wine on the market. Granular impurities, drinking soon diarrhea symptoms, she suspected she drank inferior red wine.
subsequently, a reporter search found that a trading company announced the production process of fake red wine on the official website. An insider in Ji'nan also revealed to reporters the hidden rules of blending the counterfeit wine industry.
this period women's news laboratory, experimenters use grape flavor, edible pigment, alcohol and other "red wine", verify the "three fine water" online blending of wine method. This phase of the experiment will be presented to you through video. Sina official micro-blog (@ metropolis women's news Lab) will also be synchronized.
vase wine only spent two yuan
July 1st, the reporter searched for "wine blending formula" on the Internet, and found an article entitled "identification of false wine from the making of false wine". The article provides materials such as water, pigment, essence, alcohol and so on. The method of red wine is described, and the proportion and order of material blending processing are described. The smell, color and taste of counterfeit wine are analyzed.
this article is published on the official website of "Xiamen Xiamen Thai Trading Co., Ltd.". In July 3rd, the reporter called the company, and a staff member refused the interview on the grounds that the person in charge was not there.
in July 2nd, a person who had been engaged in the production of wine to the reporter introduced the method of blending the counterfeit wine, known as "Sanjing one water", which is the use of alcohol, essence, saccharin, water as the main raw material to make counterfeit wine.
he worked in a bulk distillery in Ji'nan. According to the requirements, distilleries can only produce bulk liquor and produce wine without qualification. But he was in charge of making "red wine" in secret. He recalls that in a factory building in the corner of the factory, he added a large number of additives such as alcohol, grape essence, pigment, protein sugar, glycerin and glycerol to a large 3 ton bucket every day. "In order to improve the taste, it sometimes adds citric acid, industrial tannic acid, artificial pigments, thickeners, preservatives and so on." There is no drop of grape juice. " He told the reporter.
next step, he seals the bucket and inflate the big bucket with a inflatable rod, "this is to make the additives together." He explained. After mixing, the distillery will test the alcohol content, and the wine precision is generally higher than 10 degrees. "This can prolong the shelf life of the wine, which is beneficial to the sale." "People come to collect wine every day, most of them are red wine processing plants." He told the reporter. They sell counterfeit red wine at a price of 4 yuan per kilogram. Customers should have at least one barrel (3 tons), and large customers will have more than 10 tons. The winery's daily sales of counterfeit red wine are over 12 thousand yuan. He said, "the actual cost of one kilogram of wine is only 2 yuan, but the price to sell to customers is doubled."
calculated at 750 milliliters per bottle, the cost of a bottle of "red wine" produced by the distillery is only about two yuan.
Step 1 grape flavor blending red wine
experimenters with edible alcohol, red yeast red pigment and grape flavor as raw material, blending the fake red wine.
first, mix it up, dripping about 1 grams of red yeast red pigment into the beaker, then add pure water. The mixture of water and pigment shows a dark red color, which is very similar to the color of wine. The experimenter then added another 15 milliliters of edible alcohol to another beaker, mixing the adjusted pigment with alcohol and stirring it well. Use the dropper to get grape flavors, dripping two drops of essence into the mixed liquid, stirring again, and quickly mixing the essence, pigment and alcohol. At this point, the mixture of liquid gives off strong pungent aroma, alcohol mixed with flavor of grape flavor, and two experimenters smell and cough at the same time.
at this time, the smell of mixed liquid in the beaker is stronger than that in the red wine, and the color is much deeper than that of the red wine. It needs to be diluted with water. The experimenters used the red wine as a reference to add the water to the mixed liquid. The color of the mixture in the beaker is shallower from the deep. Add 50 ml pure water, and when the liquid in the beaker reaches about 70 ml, the color of the mixed liquid is similar to that of the red wine.
in order to make the taste of blending wine more mellow and lifelike, the experimenter added a little syrup to blending wine. A blend of flavors without any natural grape ingredients is made.
step 2
grape juice blending red wine
then, the experimenters also use red grape juice, pure water and edible alcohol to blend red wine in accordance with another formula.
is different from the previous experiment. The experimenters used grape juice instead of grape essence and Monascus red pigment. Grape juice has higher concentration and less flavor than grape flavor, but the smell is relatively fresh and pure, with less irritation.
add 15 milliliters of alcohol into the beaker, and then add the same amount of red grape juice for mixing. At this time the liquid in the beaker presents a transparent dark purple, similar to the real red wine bought, but the alcohol is much more flavored. At this time, the experimenter added pure water to wash. As the concentration of alcohol decreases, the smell of mixed liquid gradually decreases, while the color of the liquid in the beaker also becomes lighter.
the experimenter added 40 ml of water, so that the liquid in the beaker also reached 70 milliliters. The liquid presents a transparent light red at this time. In order to make the color similar to the genuine red wine, the experimenter added a trace of red Monascus red pigment and stirred it evenly. The beaker became dark red immediately. It was very similar to the real red wine.
step 3
compare three kinds of "red wine"
the experimenters compare the authentic red wine and the two blending wine from three aspects of color, aroma and taste.
Color: three kinds of wine are dark red, very similar. But it is still found that the red wine blended with grape flavors is heavier, cloudy and not transparent. Shake the beaker, the dark red liquid hanging on the beaker wall is not easy to fade. Red grape juice blending wine, liquor liquor is more transparent, but the color is light. The red wine is naturally transparent, and the wine will not hang on the beaker wall for a long time after shaking.
aroma: red wine flavoring blended with strong aroma and aroma. Red wine blended with fruit juice has a light sweetness. The authentic red wine, wine and grape aroma are well mixed, giving out a rich and natural fragrance.
taste: the flavoring wine has the aroma of wine, but the entrance is somewhat astringent, the wine has no special sour taste, and the throat feels discomfort. The wine blended with fruit juice is sweetest, with a distinct taste of grape, wine and sweetness, and some choking when swallowing, but there is no discomfort after drinking. Authentic red wine feels sweet after entering, grape flavor is very natural and delicious, and the throat feels moist and comfortable after drinking.
comparison shows that blending red wine and genuine red wine are very similar in color and fragrance, and it is difficult for non professional consumers to identify them from these two aspects. But blending red wine is very different from authentic wine in taste.
often drinking counterfeit red wine can cause liver cancer
through the experiment, it can be seen that the fake red wine contains a large number of chemical synthetic artificial pigments and other substances.
Liu Yang, director of occupational disease department of Ji'nan occupational disease hospital, the artificial pigment contains azobenzene and other substances, slowly accumulating in the human body, and it will have a toxic effect for a long time. Experimental studies have shown that artificial pigments can induce liver cancer in animals and cause damage to the digestive tract and bladder. It can also cause low toxic methemoglobin hemoglobin, which is characterized by hypoxia of human cells and adverse effects on the nervous system. Contact with artificial coloring will stimulate skin and lead to dermatitis, which can also cause asthma and other diseases through inhalation of respiratory tract.
the average consumer is hard to tell the true and false
the reporter found a lot of ways to identify red wine on the Internet. "Paper towel identification" is to take a high quality paper towel, pour the wine on the paper towel, the wet trace of the authentic red wine on the napkin is uniform red, and generally no water trace is spread. The fake red wine usually pigments on the napkin and water stains spread outward.
Sun Lei, member of manager of Huayue club, COFCO, has been engaged in wine appreciation for many years. In the afternoon of July 3rd, he said in an interview with reporters that "paper towel identification" could identify fake red wines that were completely blended with alcohol, essence and pigment, but there were some defects in this method. The principle of "paper towel identification" is based on the natural pigment of artificial pigment particles larger than the grape itself, so the diffusion degree of artificial pigments on paper napkins is less than that of real wine. It is not accurate to use paper towels to identify inferior red wines with high imitation or grape juice blending.
Sun Lei introduced, now a lot of fake red wine production technology is more and more fine, the general consumer is difficult to identify, the most effective way is consumers to contact wine more, accumulate wine experience, through color, aroma, taste and other different varieties of wine, identification of fake and inferior wine. "Generally speaking, 200 yuan and below the wine, the price is directly reflected in the quality of the wine, the very low price of the wine, can basically be determined as inferior or even fake wine." Sun Lei said. If consumers are not satisfied with the quality of the wine they purchased, they can find reputable wine distributors for tasting.
