A 10% aqueous solution of ethyl alcohol is gradually reduced from the top of the vat and the air is transferred in a controlled amount through holes near and below the vat. Ethyl alcohol is added to acetic acid. This process is called the rapid vinegar process because vinegar forms very quickly.- The first step is an anaerobic fermentation (alcoholic fermentation of sugars into ethanol by yeasts) and the second step is an aerobic fermentation (oxidation of ethanol into acetic acid by AAB).
