It was listed as a tribute during the Wanli period of the Ming Dynasty, hence its name. This wine is as clear as crystal, fragrant as orchids, sweet and mellow in the mouth, and has a long-lasting aftertaste. The method of sensory identification of the authenticity of Gujing Gong wine is as follows: (1) Identification of outer packaging and bottle stickers. The bottle sticker of genuine wine is a fully registered trademark, and the registered trademark "Gujing Gong" is used. The registered trademark pattern is circular, with a locust tree on the left, an ancient well under the tree on the right, and blue sky and white clouds on the top. The circumference is a double circle surrounded by gold, with the words "Registered Trademark" on both sides. The label on the bottle has the four-character official script "Gujing Gongjiu" written in red gold on a white background. The name of the factory is printed in white square characters on a red background. The domestic seller is "Anhui Haozhou Gujing Winery" and the exporter is "China Cereals, Oils and Food Import and Export Corporation (Anhui)". The production date, batch size and inspection certificate are printed on the back of the bottle sticker. The circular patterns on the fake wine bottles are similar to the real ones, but they are not registered and use different company names. The production date and batch size in the wine box are inconsistent, and the packing list is missing. (2) Seal identification: Real wine is sealed with a yellow lead fracture cover, which is smooth and round, with the ancient well pattern and the words "registered trademark" printed on it. Counterfeit wines are also bottled in real wine bottles, but the caps are usually broken and the seals are not round. (3) Identification of wine quality Real wine has the characteristics of clear and transparent color, no overflowing cup, rich cellar aroma, sweetness and refreshing, while fake wine has a turbid body, floating impurities, spicy and bitter taste, and some even contain a large amount of Lead, methanol and other substances are harmful to human health.
