Regular vinegar starts as a fermented juice or liquid of some kind - red wine, apple cider, sake, beer, etc. Then acetic acid bacteria (acetobacter) is introduced, which converts the alcohol to acetic acid.
Distilled white vinegar is made somewhat different. What they do is dilute distilled alcohol with water and then add the bacteria culture. Unlike other vinegars, this type doesn't really begin its life as fruit.
