A woman named Wang Xing is brewing wine at her home in Hunan. After soaking for 10 days, she noticed that the wine seemed to swell and overflow, and quickly went forward to wipe it. Unexpectedly, the wine suddenly exploded, and the splashing glass cut Wang Nv's hands on the spot, causing many injuries to her nerves, blood vessels and tendons. She was rushed to the hospital.
The deputy chief physician of the Department of Hand and Foot Surgery of the First People's Hospital of Chenzhou reminded that if you try to make your own wine, don't fill it too full. Generally, there should be 65,438+0 space in the container, and the lid should not be too tight, because wine will produce a lot of gas during fermentation. If there is more and more gas in a completely closed container, it will produce great pressure. Once the allowable limit of the container is exceeded, the container will explode.
Experts disapprove of homemade wine for the following reasons:
1. Self-brewing is easy to sterilize and incomplete.
For the sake of hygiene, most people will wash the grapes with water before brewing, but this will increase the water content of grapes and reduce the sugar content. The sugar content of fresh grapes is not as good as that of wine grapes, which will make things worse. Self-brewed containers are often sterilized by boiling water or boiling water, which is far less thorough than the closed sterilization in industry, and it is easy to breed miscellaneous bacteria, which will also lead to fusel oil or methanol exceeding the standard.
2. The homemade grape variety is wrong.
Usually, homemade grapes are not wine grape varieties. The nutritional components of wine are mainly determined by the content of polyphenols (tannins, anthocyanins, phenolic acids, flavonoids) in wine, and the source of polyphenols is the grape itself. At the same time, acidity and astringency are the taste components of wine, astringency comes from grape skin, and the color and aroma of red wine also come from grape skin.
3. Self-brewing is prone to explosion danger
Generally, most homemade wines are wide-mouth glass bottles. If there is no cover and no vent hole, it is easy to cause microorganisms to enter the bottle. In order to prevent microorganisms from entering the bottle, ordinary homebrew wine lovers will choose sealed brewing.
