"The quality of wine brewed in small workshops in rural areas is difficult to guarantee. Although this traditional process can avoid some risks after thousands of years of experience, security risks still exist." According to the analysis of relevant professionals, there are many reasons why the wine brewed by small workshops in rural areas is "unreliable": it may be brewed by deteriorated grain; Miscellaneous bacteria may be produced if the temperature and acidity are not well grasped in the fermentation process; If the temperature is not in place during distillation, toxic and harmful substances may be separated into wine; Canned containers are easy to breed bacteria without disinfection; In the production process, if the utensils are heavy metal products, heavy metals will be brought into the wine. Therefore, in order to ensure human health, the professional suggested that citizens should try to choose regular shops and buy liquor with the "QS" logo, that is, the production license logo. At present, there are only two liquor enterprises in our county that have obtained liquor production licenses. According to the regulations, the local shochu brewed by the villagers themselves is absolutely not allowed to be sold externally.
