How to distinguish between true and false pure grain solid-state fermentation to brew liquor

wine culture, as a kind of traditional China culture, has penetrated into the hearts of everyone in China. On holidays and various festive occasions, everyone raises a glass to drink. Therefore, since ancient times, there has been a saying among the people that "there is no table without wine". However, according to authoritative media reports, 7% of liquor in the market is blended with edible alcohol, so how can we know what kind of wine we are drinking? Therefore, not long ago, the reporter specially visited Gu Yangkang, a domestic brand of pure grain wine, and interviewed the person in charge of Gu Yangkang's pure grain wine, telling some consumers the method of distinguishing between true and false grain wine.

It is reported that Guyangkang pure grain wine brand is a grain wine that promises to be made only without adding or blending alcohol in the domestic wine sales industry. And take "real pure grain brewing refuses alcohol blending" as the market positioning and selling point of the product, and strive to build a healthy wine brand. The person in charge of Gu Yangkang said in an interview that edible alcohol blended wine has a wide range of existence in the market because of its low cost. For consumers how to distinguish non-grain brewing, we can mainly start with the brewing method. Solid-state fermentation is a traditional process in pure grain brewing, which consists of several technological processes, including crushing grain raw materials, steaming, cooling, fermentation, distilling wine, filling jars and cellaring. The whole process is very complicated and tedious, and the production time period of wine is long. Considering the labor and raw material costs in the production process, it is much higher than that of alcohol blending. In addition, due to the limited sales channels of traditional wine, when it reaches consumers, it has been changed hands by many dealers, and each floor will earn the price difference, resulting in the high price of traditional pure grain solid-state fermentation wine, so only high-end wines with big brands are the real traditional pure grain solid-state fermentation wine in the market. Guyangkang pure grain wine adopts brand direct marketing, which not only ensures the production process of traditional pure grain solid state fermentation brewing wine, but also eliminates the layer-by-layer price increase of dealers, and the profit is relatively low, which makes the traditional pure grain solid state fermentation brewing wine realize the price close to the people for the first time. The whole process of traditional solid-state fermentation of pure grain is produced by traditional technology, and there is no link of adding essence and spice. After drinking, consumers will not feel head-up, dry mouth, etc., and will not feel weak the next day when drinking alcohol blended wine. Moreover, drinking pure grain in moderation is very beneficial to the health. Additives such as alcohol, essence and sweetener will be added in the blending process of edible alcohol blended wine, and consumers will have a headache and dry mouth after drinking.

In view of the fact that 7% of liquor products sold in the market are alcohol blended liquor, the person in charge of Guyangkang Pure Grain Liquor told the reporter several practical and simple ways to distinguish the difference between grain brewing and alcohol blended liquor, so as to help consumers accurately distinguish good wine from inferior wine.

1: put a drop of white wine in the palm of your hand, then cross your hands to make the two palms contact and rub hard for a few times. If the wine smells fragrant, wine aroma and bad after heating, it is really pure grain wine; If it is blended with edible alcohol, it not only smells bad, but also has a short taste, which will be tasteless after a while.

two: pour the wine into the glass and then pour it out. The alcohol blended wine is choking when you smell the empty glass, and it is alcohol blended wine when you smell the wine aroma in the glass for about ten minutes. It is pure grain brewed wine that has the flavor of grain, wine aroma and bad flavor.

third: use sodium hydroxide, which is commonly referred to as caustic soda. Put the liquor to be tested in a test tube at the ratio of 5: 1 caustic soda, or use the cup that can be heated in our usual home, and then add hot water to boil for a few minutes. If it is grain-brewed liquor, the liquor in the test tube will turn yellow. If the color is very light, it is pure grain wine that is impure and contains alcohol blending ingredients. Do not change color for pure alcohol blending wine, because inferior liquor is blended with alcohol and spice sweeteners, and will not react chemically when encountering caustic soda.

fourth, the method of self-experience: the real traditional grain brews wine fragrance without choking, slightly bitter but not astringent. The aroma of grain, wine and bad smell is obvious, and the mouth is full. From the tip of the tongue to the root of the tongue, it is full of sweetness, with a good aftertaste and a long retention time. After drinking, it does not dry mouth and headache, and it will wake up quickly after drunkenness, which will not stimulate the brain. The most important thing is that people are in a state of drunkenness and understanding after drunkenness, and they are not uncomfortable or tired the next day. Drinking alcohol blended liquor is more stinging to the throat, and it is very irritating to the brain after drinking it. Therefore, it takes a long time for alcohol blended liquor to wake up after being drunk, and the drunken person is in a state of numbness, and the body is uncomfortable the next day.

according to the verification method provided by the person in charge, the reporter bought a brand wine of more than 8 yuan from the market and compared it with Guyangkang pure grain wine according to the above chemical identification method. After the test, it was found that the overall yellow color of Guyangkang pure grain wine in the test tube was relatively deep, while the wine bought in the market for more than 8 yuan was only slightly pale yellow, which proved that the grain content was not high. It is believed that consumers will be able to choose alcohol brands that are responsible for their health and are guaranteed in future alcohol purchases after mastering these identification methods taught by the person in charge of Gu Yangkang.
