The "Qingdao Brand" beer produced by Qingdao Brewery in Shandong Province is famous at home and abroad for its excellent quality. It is not only a famous beer that consumers especially admire, but also one of the fist products of China's export to earn foreign exchange. The methods of sensory identification of Tsingtao beer are as follows: (1) The overprint of bottle stickers to identify the real goods is accurate and clear, the color is positive and shiny, and the fake goods are printed coarsely. (2) The false overprint of the bottle cap identification is incorrect, and the matte printed iron pattern is clear and firm in color, and the inner pad is injected with a gasket. However, the printed iron patterns of counterfeit bottle caps are not firmly attached, and some of them fall off. (3) The standard bottle types for identifying genuine goods are all sliding shoulder bottles, and the bottles are all branded with Sanbei brand. False bottles are mixed and varied, and there is no uniform mark. (4) Identification of wine quality The real wine is clear and transparent, with light golden yellow color, fine and durable foam, sufficient carbon dioxide, soft and refreshing when drinking and obvious bouquet. The false color is dark, with few bubbles, impurities or precipitation.
