Vinegar is a sour liquid used as a condiment or as a preservative. It is obtained through the fermentation, or the artificial oxidation, of ethanol.^[1]

According to an alchemical work dating back to the 1550s, vinegar is used in the making of the perfect medicine, along with Salt, Urine, Sal Ammoniac and a particular Sulphur Vive.^[2][3]

Turning vinegar back into wine (and thus reverting the fermentation/oxidation process) is part of the sixth year Charms curriculum at Hogwarts School of Witchcraft and Wizardry.^[4]
