How long does it take for vinegar to evaporate?

Vinegar does not evaporate; instead, it undergoes a process called acetic acid fermentation. During fermentation, the bacteria present in vinegar convert the alcohol in the liquid to acetic acid, giving vinegar its characteristic sour taste and smell. The rate of fermentation depends on several factors such as temperature, pH, and the type of bacteria present, but under normal conditions, it can take several weeks to months for vinegar to fully ferment. Once the fermentation process is complete, vinegar can be stored indefinitely as it is resistant to spoilage caused by most bacteria and fungi.
