There have been many articles about the harm of homemade wine, but there are still many people who think that this is a routine of wine sales, and it is not allowed that homemade wine is because wine sellers want consumers to buy wine to drink. But in fact, the harm of homemade wine is by no means alarmist.
1, homemade wine is easy to breed mold.
Grapes used for wine-making need high maturity, no damage, no mildew and so on Grapes are not easy to preserve at room temperature and are prone to mildew. If the freshness is not high, it will make the wine more moldy. Moreover, most of the grapes bought in the market are sprayed with pesticides to avoid being bitten by insects, and they cannot be thoroughly cleaned during the brewing process, which leads to the doping of harmful substances in the wine.
Bottled wine produced by regular manufacturers, almost every grape will undergo strict selection and picking in harvest season to ensure its high maturity, no damage and mildew. In order to keep the picked grapes fresh, the winery will brew them at the first time.
2. Self-made wine containers are prone to chemical reactions.
Friends brew their own wine, usually with mineral water bottles, buckets, vats and so on. As a container for brewing wine at home. In fact, these containers may react with wine and produce substances harmful to health.
The brewing equipment used by regular manufacturers is also standard stainless steel cans, and some high-quality bottled wine will also use the best aging container-oak barrels. Oak barrel is beneficial to improve the color and taste of liquor, increase aroma and enhance the sense of structure and fullness of liquor.
3. The sugar content of homemade wine is too high, which is easy to harm health.
Speaking of homemade wine, friends will mention the word "sweet". Because in the process of brewing, adding more sugar is helpful to fermentation, although the improvement of sweetness can cover up other odors, if adding too much sugar will be harmful to human body.
In fact, in the process of wine brewing in developed countries, people have made rounds of hard exploration to make wine contain less sugar or even no sugar. If the wine body can not be completely sugar-removed, the yeast will still survive, which will lead to the change of alcohol content and taste (even sour and smelly) during storage. If you want to drink wine with higher sweetness, you can choose iced wine or noble wine. Bian Xiao also has a soft spot for these two wines.
4. The fermentation time and temperature of homemade wine can't be controlled.
Many people can drink their own wine recently. Bian Xiao refers to the bumper harvest of grapes a month ago, when people began to brew their own wine. Can grapes be fully fermented to make good wine this month? Moreover, in late summer and early autumn, the temperature at home changes greatly, and the quality of wine cannot be guaranteed.
In general, besides fermentation, wine needs to be stored and aged. The aging time of high-quality wine needs 1-2 years, while Polygonatum sibiricum used for brewing and storage needs constant temperature and humidity. The gap between 1~2 months and 1~2 years is too big.
5. Homemade wine hides harmful substances.
Self-made wine may contain methanol and fusel oil, which has certain toxic and side effects on the body. Many people feel sick after drinking too much homemade wine. Because the brewing equipment at home is not up to standard, it is difficult for the self-made wine to meet the hygienic standard, and there may be a situation in which Escherichia coli exceeds the standard, resulting in gastrointestinal discomfort.
Bottled wine in regular wineries realizes the whole process of closed disinfection production, sterilization and filling; In addition, sulfur dioxide is essential in the brewing process of winery wine. Its main function is to prevent oxidation and sterilization, and it can also kill bacteria and wild yeast in grape powder cream.
6. The content of "phenol" in homemade wine is less.
As for the nutritional components, according to the identification of the sommelier, the self-made wine has less phenolic substances, which is still far from the wine produced by regular manufacturers.
What about homemade wine? It's not like you can't drink it. You should pay attention to hygiene and storage places.
