Vinegar is a liquid obtained from the fermentation of the alcohol of the wine or a solution alcoholized in acetic acid. The first reference to this product dates from the time of the Roman Empire and it is estimated that its use in the kitchen would be related to the production of alcoholic beverages.
It is known that this liquid is obtained from the activity of the bacteria of the type "Mycoderma aceti" that cause a chemical reaction fermenting the alcohol of the wine. This process ends when there is no longer a high concentration of alcohol in the drink.
However, until 1864 there was no evidence, or had not been explained scientifically, how the vinegar was produced. It was in this year when the renowned chemist Louis Pasteur detailed its production process, giving rise to the "Pasteur Method or Orleans Method". From this would arise other methods for the production of vinegar.
Currently there is a wide variety of vinegars. Vinegars are sold for 6 months, 2 years and up to 10 years. Its flavor becomes more intense over the years.
