Distilled vinegar, commonly known as white vinegar, is a type of vinegar produced through a fermentation process that converts ethanol into acetic acid. The production involves two main steps: first, the fermentation of a distilled alcohol source, such as grain alcohol, into acetic acid by acetic acid bacteria; and second, the purification of the resulting acetic acid through distillation, which removes impurities and concentrates the acid. It is commonly used for pickling, salad dressings, and marinades.
