Let me give you some simple information. Physical chemistry is useless. Practice is very important.
Wuliangye
According to market spot checks, Wuliangye is the most counterfeit famous wine. Standard for paper, printing and color of genuine Wuliangye trademark. The words "Wuliangye" are intaglio printed, with smooth surface, protruding feeling, clear font, hairless edges, complete font lines, saturated overall color, accurate overprinter, net content on beautifully printed trademarks, and clear small characters such as alcohol content, raw materials, factory name and address in the lead printing part.
The counterfeit "Wuliangye" trademark has rough printing and the strokes of the word "Wuliangye" are broken. The ink is not smooth, the overall color is not full and uneven, and the font edge is fuzzy and rough.
From the bottle body, the genuine glass is made of high white material or flexible white material, with elegant shape, glass, transparency, uniform and exquisite overall, no bubbles and wrinkles, and clear and correct font on the bottle body. The bottle is rough, with wrinkles and bubbles, and the words on the bottle are not clear. The external interface of Wuliangye bottle cap (i.e. lock mouth) is smooth and flat. Is there an anti-counterfeiting mark on the bottle cap of Wuliangye, and is the mark formal?
Wuliangye bottle cap adopts metal twist cover, which has golden color and good finish. The factory emblem pattern is printed on the top of the cover, the surrounding fonts are clear and correct, and the lock mouth is flat and smooth. There are two anti-counterfeiting measures at the top of the bottle cap: one is lithography. From July 1, 1 and 10, the logo of Wuliangye Winery was engraved on the top of Wuliangye drum bottle cap and crystal bottle cap respectively. Observing with a magnifying glass of 10 times, it is obvious that the lines are slightly burned by the laser. The second is invisible code spraying. From 1994 65438+ 10/month 1, dark spraying was used on plastic and crystal Wuliangye bottles. Under the irradiation of purple light, you can see the blue factory emblem pattern and "WLY" (the Chinese phonetic abbreviation of Wuliangye). The whole pattern has uniform color, clear lines, clear outline and no fracture. It is used to slightly twist the bottle cap in the direction of the arrow.
Counterfeit Wuliangye wine bottle caps, patterns and words are not correct, which is regarded as shoddy. The aluminum used is thin, dull in color, poor in finish, low in locking process, uneven and smooth, and some even have dents caused by hard extrusion. Some counterfeit Wuliangye bottle caps also have fake anti-counterfeiting marks, but most of the counterfeit photoetching patterns are hard extruded, and the patterns and lines are white, and the lines are blurred and broken. Some of them can be wiped off with wet cloth, and very few counterfeit code-sprayed patterns, and some lines are poorly connected and blurred.
On June 1995 and 10, the factory introduced Wuliangye advanced anti-theft cover. High security improvement (red), the lid is imported from Italy, which is characterized by pouring wine from the bottle mouth, but not filling it. The cover is bright in color and smooth, with the words "Wuliangye" printed on it. There is a drawstring at the upper and lower ends of the cover, and there is a golden aluminum ring on the drawstring. The counterfeit Wuliangye red anti-theft cover is dark in color and poor in smoothness, and there is often a circle of protruding marks in the middle of the cover. You can feel it by touching it with your hands.
On the back of the label attached to Wuliangye bottle, you can find the production date marked with blue seal through the glass bottle. The production date is expressed in two digits. Connect the middle with a horizontal line, such as "96-0 1-20". The batch number is a 6-digit string starting with 85, and there is a space between the 5th and 6th digits, such as "85654 6". Most fake wine labels have poor quality, uneven colors, blurred font edges and broken lines. There are often gaps in the outer ring of the registered trademark mark R, and the printing ink used is dim and uneven. Pay special attention to whether the black edge of Wuliangye is close to the golden background, and the golden color exposed outside the black edge is a very important feature of fake wine labels. The tight bite between the aluminum lid and the bottle mouth is another sign of fake wine. Some can even rotate at will, and even leak wine after inversion. The production date and batch number "year, month and day" are printed on the back of the label, but they are not separated by horizontal lines, and some are "1995" and "1996".
Represents the year. Some also use Chinese characters to mark the year, month and day, or use red seals to print the date of production. These are all fake Wuliangye.
1996 since the second half of the year, some cities such as Beijing and Kunming have successively discovered "high-cover" fake wines. We can pay attention to three aspects in identifying these fake high protective covers: first, the fake protective covers are dark in color and poor in smoothness, and there are often a circle of protruding marks in the middle of the protective covers; Second, the adhesion between the words printed on the cover and the plastic is very poor. Just scratch it with your nails and it will fall off. Third, the bottle cap can't be screwed tightly, and it can keep spinning. From June 22, 65438 to June 22, 0996, Wuliangye liquor will use crystal carved vases, and the glass material is crystal clear. The fake Wuliangye glass material is poor, and the bottle body often has obvious wrinkles and bubbles, the bottle body is not straight, and the color is green. Certificate identification: The certificate paper used by Wuliangye Winery is thick, printed with gold cards, clear printed patterns and characters, and stamped with quality inspection seal on the back. The fake certificate paper is rough, fuzzy and dark in color.
Physical and chemical identification of Wuliangye: 52%, 39% and 35% all meet the national standards GB/T 1078. 1 and GB/T 1 1859.438+0. Sensory identification is an important standard to distinguish genuine Wuliangye from fake Wuliangye. The unique style of Wuliangye liquor can be summarized as: long aroma and mellow taste. There is only one inconsistency in the above identification, which can be judged as fake wine.
Since 1980s, "Wuliangye" has taken a series of anti-counterfeiting measures, and has gone through four price stages: hot film gluing of plastic cover, disposable metal bottle cap, laser engraving with fluorescent invisible code spraying, and triple anti-counterfeiting cover of Italy. Although these anti-counterfeiting measures have achieved certain results, they still failed to finally curb the counterfeiters' fraudulent means. 1In September, 1996, Wuliangye Winery cooperated with American 3M Company, and took the lead in reaching an agreement to make "3M Retroreflective Anti-counterfeiting Film" in China. The first phase of the project invested 200 million yuan, which made Wuliangye's anti-counterfeiting technology enter the latest and highest level in China.
Wuliangye's "3M Retroreflective Anti-counterfeiting Film" is based on the principle of light retroreflection. On the special anti-counterfeiting bottle cap of Wuliangye, glass beads with a diameter of 0.06mm were coated on the surface of visible printed matter with light to form a specific Wuliangye factory emblem pattern to protect the visible part of printed matter. Under natural light, consumers can clearly see the Wuliangye anti-counterfeiting logo in scarlet letters on a white background, and then use a hand-held special detector to see that the original Wuliangye scarlet letter logo is hidden, reflecting the dazzling Wuliangye factory emblem, and the authenticity can be immediately identified.
Maotai
Identification of Maotai Liquor
Manufacturer identification
Maotai Distillery is not associated with any other distillery, nor has it authorized any manufacturer to enjoy its trademark license, nor has it set up a factory, a second factory or a branch factory. Any "Moutai" marked with joint venture factory, factory, branch factory and branch factory can definitely be fake.
(2) Identification of sales channels
The sales of Moutai are distributed according to the national plan. Domestic sales are uniformly allocated by renhuai city Tobacco Sugar Company, while export sales are uniformly allocated by renhuai city Foreign Trade Company. The sales voucher of Moutai is a sales slip, ticket head and special seal. There is no word "Renhuai County" on these three, and if there is, it is also fake. Maotai liquor has no grades, and there is no distinction between positive and negative products. If there is a result, it must be fake.
(3) Farewell to registered trademarks
The registered trademark of "Kweichow Moutai" is pasted on the whole bottle of Moutai, and printed on imported coated paper with a capacity of 500ml, and the specification of the trademark paper is 90mm x 125mm. The logo of domestic wine merchants is divided into three parts: a 60 mm wide white belt in the middle, two thin black lines and four thick black lines up and down, with the red words "Kweichow Moutai" in the middle. There is a gold bar with a width of 13 mm at the junction of the diagonal bar and the upper left corner, and there are four black characters "famous at home and abroad" on the bar. In the upper left corner is a red color block with a white circle with a diameter of 35 mm in the middle. There are annular ears of wheat, golden gears and red five-pointed stars from top to bottom in the circle. There is a thin gold thread at the junction of the diagonal belt and the lower right corner. On the red color block in the lower right corner, there are eight white characters "Produced by China Maotai Distillery", and below the white characters, there are black characters "53%VOL, 500ml" to indicate the alcohol content and capacity. The back of the bottle is 65mm x 85mm with a red edge and a white edge with a width of 10mm around it. The factory date is blue Arabic numerals, and the trademark is beautifully printed, with accurate color and even trimming. For export products, Tian Fei brand is the registered trademark, and there are two streamers of "China Kweichow Moutai" in white on a red background, with bilingual instructions on the bottle.
The trademark and adhesive of fake Maotai are generally printed on ordinary paper. The trademark specification is 100 mm X 140 mm, and the adhesive specification is133 mm x 85 mm. ..
The colors of various patterns are confused, the levels are unclear, the colors are light, the specifications are inconsistent, and the fonts used are obviously different from the real trademarks. The date of manufacture is written in red, and some are replaced by other colors.
(4) Identification of packaging materials
The bottle of Moutai is a milky glass bottle, sealed with a twist-off anti-theft aluminum cover with a big red line, with five white characters "Kweichow Moutai" on it, and the bottle mouth has no internal plug. The whole bottle of wine is wrapped in high-quality square kraft paper and packaged in color box; The outer packaging color box adopts imported white board paper and red corrugated paper, and the font and color on the box are consistent with the trademark and back label.
The bottles of fake Maotai are often sealed with different shades of red rubber caps, some are transparent and wordless, and some are fake Maotai. These hats are white, and some are red. The cover also has different wall patterns, such as yellow twisted aluminum cover, plastic sleeve twisted yellow aluminum cover, screw plug, waist line, flat top and so on. The outer packing box uses unqualified inferior leather or other materials. In recent years, the bottle cap is made of red plastic, and the bottle mouth is sealed, which has the function of non-return.
If you want to identify the authenticity from the packaging, you should first pay attention to the exquisite printing of the packaging carton. If the surface of the carton is not smooth and wrinkled, it is extremely suspicious. After opening the lid of Maotai, you can find that the transparent plastic rubber cap on the bottle mouth is printed with the words "Maotai" by ink jet, and the production date and batch number are printed on the side in small print. This is a special mark. The genuine product is characterized by clear and unambiguous ink-jet handwriting, which won't fall off with a slight stroke by hand. Fake handwriting is not clear, and it will become blurred with a light brush. Tian Fei brand Moutai, the logo of "Tian Fei" on the upper corner of the label is an important symbol to identify the authenticity. The red and yellow colors on the genuine Tian Fei ribbon are very close and will not be exposed outside the frame; Fake prints are rough, and colors often run out of the border. In addition, the pink faces, arms and feet of women in Tian Fei will have pink fluorescence when observed under ultraviolet light. After taking out the bottle, pay attention to whether the red plastic lid and plastic mouth are tightly engaged. If it can be rotated or even inverted at will, it is suspected of leaking wine. The ivory glass bottle of aristocratic Moutai is a unique bottle type, and it is abnormal that the bottle body is blue or even light green or light blue.
In addition, starting from 1 99865438+1October1,Maotai adopted the high-tech products of American 3M company and printed reflective labels on each bottle of Moutai. When customers buy Moutai on the wine cabinet in the store, they just need to put the small hole on the top of the special recognizer for Moutai close to their eyes, press the switch of the recognizer, and the word "Maotai" on the bottle cap of the main spotlight disappears, and the dazzling MT watermark is reflected on the label to show the authenticity.
(5) Recognition of taste characteristics
Maotai liquor is a wheat starter, which needs eight fermentations and two or three years of cellar storage before leaving the factory. Its unique sensory index is that liquor is colorless and transparent, mellow and sweet when drinking, without suspended matter and precipitation, with outstanding sauce flavor, elegant and delicate, full-bodied, long aftertaste and lingering fragrance of empty cups. Fake Moutai is mostly made of sorghum, white dry wine and mixed wine, so it is difficult to have the color, fragrance and taste of Moutai.
