in a previous answer it has been stated-:
Vinegar is produced by two successive microbial processes. The first being an alcoholic fermentation (which is Haraam) and the second an oxidation of alcohol by aceto bacter, when it's molecular structure is changed and it ceases to be an intoxicant.

In vinegar the intoxicating factor is destroyed by the microbial process of oxidation hence it becomes permissible. Islam permits any variety of vinegar to be used as a condiment or preservative.
