Vinegar is a food condiment traditionally made by using an acetic acid forming bacteria (such as those in the genera Acetobacter and Gloconobacter) and to ferment wine or similar ethanol-containing liquid. In modern times, white vinegar is produced chemically, as it is essentially dilute acetic acid.
In addition to its many culinary uses, vinegar is also commonly used to clean glass, cutting through grease and leaving a smear-free finish.
