How to explain the problem of brewing vinegar?
Wine turns into vinegar because
1. In the brewing process, the sealing work is not in place, and the wine begins to oxidize without fermentation. Bacteria change alcohol and turn it into an acid. This process is called secondary fermentation or acid fermentation.
2. In the brewing process, if the fermented fungi are not well controlled, the wine will become vinegar.
3. In the secondary brewing process, too high temperature will also lead to brewing into vinegar.
