How to identify true and false beer?

Identification of true and false beer 1. The logo on the outer packaging of beer. The label pattern of real beer products is clear, the color is bright and the surface feels concave and convex; (2) The label of counterfeit beer products is vague, the color is light, the paper texture is not good, and it is easy to wrinkle. For example: 1. The real Jinwei commodity label has laser marking for anti-counterfeiting, and the fake one has no laser marking. The labels of the real Pearl River and Tsingtao Beer are very clear, but the fake ones are rather vague. 3. Because the bottle cap of counterfeit beer is re-pressed, it is loose. Sometimes, consumers can take off the bottle cap with a little force. The beer lid is really pressed tightly and can only be opened with the help of tools. Second, identify from the smell (1) If the bottle cap of counterfeit beer is pressed again, the seal will not be tight, and the aroma of malt liquor in the bottle will evaporate, and the beer will have no bouquet. (2) When the lid of real beer is opened, it smells very fragrant. Third, from the bubble identification when opening the wine (1) Because the counterfeit beer is not tightly sealed, the carbon dioxide in the bottle will volatilize, and there will be no bubbles or few bubbles when opening the beer or pouring the wine into the cup. (2) There are many bubbles in real beer, and even beer overflows from the cup. Fourth, from the taste identification (1), the counterfeit beer has a light taste and no beer flavor. (2) Real beer has a rich taste and a strong wine flavor.
