Halocho #1416 - Vinegar

Vinegar made from non-Kosher wine or non-Kosher grape juice is not Kosher.

Vinegar made from Kosher wine or grape juice that was not boiled, can still become non-Kosher if a non-Jew touches it, unless the vinegar is so strong that it bubbles when poured onto the ground.

On Shabbat it's forbidden to add liquids into vinegar with the intent of making more vinegar.
