the method of sensory identification of maotai liquor is as follows: the manufacturer identifies that maotai distillery has not been associated with any other manufacturer, nor has it enjoyed the trademark license right with any manufacturer, nor has it set up a factory, a second factory and a branch factory. Any "Moutai" marked as a joint venture factory, a factory, a factory or a branch factory is definitely fake. Identification of Registered Trademarks The whole bottle of Moutai is affixed with the registered trademark of "Guizhou Moutai", which is printed with imported 1g steel plate paper, and the specification of the trademark paper for a 5ml capacity bottle is 9mm× 125mm. The logo of domestic wine merchants is divided into three parts: in the middle, there is a 6 mm wide white diagonal belt from the upper right to the lower left, and there are two thin black lines and four thick black lines on the upper and lower sides respectively, which sandwich the red word "Guizhou Moutai" in the middle. There is a 13-mm-wide gold strip at the junction of the diagonal belt and the upper left corner, on which there are four black words "famous at home and abroad". In the upper left corner, there is a red color block, and there is a white circle with a golden edge in the middle with a diameter of 35 mm, and there are annular wheat ears, 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 under the white characters, there are black characters "53%VOL, 5mL" indicating the alcohol content and capacity. The specification on the back of the bottle is 65 mm× 85 mm, with a red edge, and a white edge with a width of 1 mm is left around the edge. The factory date is blue Arabic numerals. The trademark is beautifully printed, with accurate colors and even trimming. The trademark and back sticker of fake Maotai are printed on ordinary paper, with the trademark specification of 1mm× 14mm and the back sticker specification of 133mm× 85mm. 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 factory date is written in red and in other colors. The packaging material identifies that the bottle of Moutai is a milky white glass bottle, sealed with a big red thread twist-off anti-theft aluminum cover, with five white words "Guizhou Moutai" on the top, and the bottle mouth has no internal plug. The whole bottle of wine is wrapped in a high-quality square leather paper and packed in a color box: the outer packaging color box is made of imported white paper and corrugated. The font and color on the box are consistent with the trademark and back sticker. At present, Moutai has used three layers of anti-counterfeiting, one is the laser sign of round five-star gear wheat ear or flying, the other is the anti-theft cover imported from Italy, and the third is the watermark reflection label imported from 3M company in the United States. The fake "Maotai" is sealed with different shades of red rubber caps, some are transparent without words, and some are fake "Maotai". The bottle caps are white and red. The cover also has different wall patterns, including yellow twist-off aluminum cover and plastic cover with twist-off yellow aluminum cap. There are several kinds of inner plugs, such as spiral type, belt waist line and flat top. The outer packing box is made of unqualified and inferior leather paper or other materials. Identification of sensory characteristics Maotai liquor is made from wheat, fermented for eight times and stored for two or three years before leaving the factory. Its unique sensory index is that the liquor is colorless and transparent, mellow and sweet when drinking, without suspended matter and precipitation, with outstanding aroma, elegant and delicate, full-bodied wine, long aftertaste and lasting fragrance in empty cups. A table of food and a casual banquet, as long as there is a bottle of Moutai on the table, the grade will be very different immediately. As soon as Moutai is opened, it gives people an inexplicable excitement, followed by a strange fragrance overflowing the room, which surprised everyone. After smelling the fragrance, put it into the cup and observe its color. It is yellowish and transparent, pure and without precipitation. Raise a glass and shake it gently. Facing the sunlight or moonlight, you can see the thin hops grow along the cup and return to extinction. Some people sum it up as four parts: testing its truth in Kaifeng, observing its color by swinging incense, savoring its flavor, and smelling its fragrance in an empty cup. Fake "Maotai" is mostly made of sorghum wine, white dry wine, mixed wine, etc., and it is difficult to have the characteristics of color, aroma and taste of Maotai. There are three types of Maotai liquor, one is sip, the other is suck, and the third is ah. The "Three Types" should be coherent, calm and seamless, attentive, attentive and relaxed, and fully mobilize the taste and smell nerves to capture, appreciate and comprehend the fragrance of each wine molecule, so as to form a perfect wine tasting procedure and obtain comprehensive aesthetic enjoyment. Sip, is to send the glass to your lips, take a sip lightly and slowly, and sip the product carefully in your mouth. Zap is to smack your mouth lightly. When you swallow the wine slowly, you will naturally make a smack or click sound. Oh, it's a quick breath on the basis of smacking, so that the alcohol smells fragrant from the nasal cavity. Leaving fragrance in an empty cup is another feature that distinguishes Moutai from other famous wines. It is not only inferior to the taste, but even better than the taste for those who are not good at drinking. An empty cup smells fragrant and tastes fragrant, which complement each other and have their own interests. After a glass of wine is dried, with the aftertaste in your mouth, move the glass close to your nose, hold your breath carefully, inhale slowly, and then inhale deeply and deeply, as if you have entered another brand-new realm.
