CONCENTRATED VINEGAR, 1000 ml

it's a fortifier obtained thanks to the action of bacteria of the genus Acetobacter which, in the presence of air, oxidize the ethanol contained in the wine and in the fruit, turning it into acetic acid. The percentage of acetic acid which originates varies according to the type of fermentation. The vinegar used in cooking contains typically a 3-5% volume of acetic acid, whereas this product can reach a 18-20% percentage. Thanks to its acidity, the vinegar is used as fortifier to lower the pH of water when carrying out treatments with organic products, some of which lose or reduce their effectiveness with a neutral or alkaline pH. When in contact with all sorts of green plants (e.g. flowers, weeds etc.) it performs a caustic action, as it changes their tissues in depth to the point of burning them (weeding action).
