Production

Commercial vinegar is produced either by a fast or a slow fermentation process. In general, slow methods are used in traditional vinegars, where fermentation proceeds over the course of a few months to a year. The longer fermentation period allows for the accumulation of a nontoxic slime composed of acetic acid bacteria and their cellulose

, known as mother of vinegar. Fast methods add the aforementioned mother of vinegar as a bacterial culture to the source liquid before adding air to oxygenate and promote the fastest fermentation. In fast production processes, vinegar may be produced in 1-3 days.

for "sour vinegar"). Cane vinegars from Ilocos are made in two different ways. One way is to simply place sugar cane juice in large jars; it becomes sour by the direct action of bacteria on the sugar. The other way is through fermentation to produce a traditional wine known as '' basi''. Low-quality ''basi'' is then allowed to undergo acetic acid fermentation that converts alcohol into acetic acid. Contaminated ''basi'' also becomes vinegar. Cane vinegar is also produced in other countries, like France and the United States. A white variation has become quite popular in Brazil in recent years, where it is the cheapest type of vinegar sold. It is now common for other types of vinegar (made from wine, rice, and apple cider) to be sold mixed with cane vinegar to lower the cost. Sugarcane ''sirka'' is made from sugarcane juice in parts of northern India. During summer, people put cane juice in earthenware pots with iron nails. The fermentation takes place due to the action of wild yeast. The cane juice is converted to vinegar having a blackish color (from ferrous oxide and acetate). The ''sirka'' is used to preserve pickles and for flavoring curries.

. As with wine, the range in quality is considerable. Better-quality wine vinegars are matured in wood for up to two years, and exhibit a complex, mellow flavor. Wine vinegar tends to have a lower acidity than white or cider vinegars. More expensive wine vinegars are made from individual varieties of wine, such as champagne, sherry, or pinot gris. The term "distilled vinegar" as used in the United States (called "spirit vinegar" in the UK, "white vinegar" in Canada) is something of a misnomer because it is not produced by distillation, but by fermentation of distilled alcohol. The fermentate is diluted to produce a colorless solution of 5 to 8% acetic acid in water, with a pH of about 2.6. This is variously known as distilled spirit, "virgin" vinegar, or white vinegar, and is used in cooking, baking, meat preservation, and

, or in the United States, corn. It is sometimes derived from petroleum. Distilled vinegar is used predominantly for cooking, although in the UK it is used as an alternative to brown or light malt vinegar. White distilled vinegar can also be used for cleaning, and some types are sold specifically for this purpose.
