It is formaldehyde and microorganisms that exceed the standard, and the alcohol content is not that low. I cherish life and don't care about the consequences of self-brewing. If I really want to brew my own wine, please study the knowledge of wine brewing seriously, and then brew according to my own situation. If I want to brew my own wine in China and there is no good source of grapes, the light equipment will cost more than 400 thousand. This is not nonsense. . . . It is much more appropriate to drink honestly and buy imported original overseas bottles than to build a car behind closed doors.
