Traditionally, the manufacture of vinegar provided a means of utilizing a large
proportion of the cull fruit from apple-packing establishments and the waste from
apple processing facilities. Most vinegar is now produced from distilled grain alcohol.
Vinegar may be defined as a condiment made from various sugary and starchy
materials by alcoholic and subsequent acetic fermentation. The vinegar bacteria, also
called acetic acid bacteria, are members of the genus Acetobacter and characterized
by their ability to convert ethyl alcohol (C2H5OH) into acetic acid (CH3CO2H) by
oxidation. Vinegar can be produced from various raw materials like distilled alcohol,
wine, rice wine and any kind alcoholic solution by several major production
techniques for making vinegar such as the Orleans process, generator process and
submerged acetification process.
