Is homemade wine poisonous? After autumn, many friends start to brew their own wine, but remind you that toxic chemicals may be produced in the process of brewing wine at home, so drinking homemade wine is at risk of poisoning. If you feel unwell after drinking homemade wine, please seek medical advice as soon as possible. 　　　　

Now, it is the peak season of grape sales, and many friends start to brew wine by themselves. However, I want to remind you that you must be careful when brewing your own wine, because the homemade wine may contain methanol, fusel oil and so on, which are toxic and harmful substances.

The relevant professional departments have analyzed the samples of homemade wine, and the results show that the samples contain different concentrations of methanol and fusel oil. The production of methanol and fusel oil mainly comes from raw materials. On the one hand, the pectin in grape skin decomposes into methanol under the action of pectinase or heat energy, and mildew will also produce a lot of methanol. The more thorough the fermentation, the higher the methanol content will be. On the other hand, protein in grapes is hydrolyzed into amino acids, and then fusel oil is generated by the catalysis of enzymes.

In addition, a lot of gas will be produced in the fermentation process of homemade wine, so don't use plastic bottles, stainless steel, aluminum utensils, etc. to avoid chemical reactions.

Although it is affordable to brew wine by yourself, at present, most families have not removed methanol and fusel oil in the process of brewing wine. Everyone should be careful when brewing and drinking wine by themselves to avoid such toxic and harmful substances from causing harm to the health.
