Harmless
If the wine is made strictly according to the wine-making process, and it is guaranteed not to be contaminated or deteriorated, drinking it will not cause any major harm to the body. Because wine made in strict accordance with the wine making process is guaranteed to be clean and hygienic, there will usually be no excessive bacteria or other substances produced. There is no big difference between the wine produced at this time and the wine sold on the market, and it can be drunk.
