Blind drinking brewed wine is not desirable

Today, many people will choose to drink their own wine, because it is cheap and can ensure that the use of materials is real, online wine widely disseminated DIY tutorials, but also makes more and more people have joined the "winemaker" ranks. However, can the homemade wine be safe to drink? Industry insiders remind consumers that self-brewed wine is not entirely risk-free, and even there have been cases of food poisoning and hospitalization, and blind drinking is not recommended.

Experts explained that the wines they brewed may contain methanol and fusel oil, which have certain toxic side effects on the body. On the one hand, the pectin in the grape skin decomposes out of methanol under the action of pectinase or thermal energy. Mould production will also produce a large amount of methanol. The more thoroughly the fermentation, the higher the methanol content will be. At the same time, the proteins in the grapes are hydrolyzed into amino acids, which are then catalytically produced by enzymes to produce fusel oil. However, at present, home-made wines do not have the process of removing methanol and fusel oil, so some people will have headaches and nausea after drinking their own wine.

Moreover, because the hardware is not up to standard, full closed-end sterilization production cannot be realized, and it is difficult for home-brewed wines to meet the hygiene standards. There may be cases where E. coli exceeds the standards, resulting in gastrointestinal discomfort.

In addition, wine brewing is a process that converts sugar into alcohol. The regulated wines remove a portion of sugars, while brewed wines not only do not remove sugar, but also add sweetness by adding sugar, and are not suitable for regular drinking, especially those with high blood sugar. Drinking is bad for the body.

As for the nutritional content, according to the sommelier's appraisal, since there are relatively few phenolic-containing substances in the brewing industry and they want to drink health care and good health, there is still a big gap between this and the real dry red wine.
