The bottle has a best by date of 2022 and was opened a few months ago.
Is that common that mold can grow in vinegar?
Best Answer
Normal vinegar concentration (usually around 5% acetic acid) is too acidic to grow mold in the vinegar itself. Mold can sometimes grow on the bottle or on the surface of the vinegar. It isn't dangerous and can be wiped/skimmed off.
What you are seeing is called the mother.
Vinegar is produce when acetobacter bacteria consume alcohol and produce acetic acid. The bacteria form a culture as they work. In the case of filtered vinegar, this culture is removed before bottling but letting a bottle of unpasteurized vinegar sit for a while will allow the culture to reform. Unfiltered vinegar often already has some of the mother present.
It is harmless and can be used to start your own vinegar if you have stale wine sitting around.

Answer 2
I was surprised to find mold growing on balsamic vinegar. Maybe it's because the top was not screwed on tightly.
Answer 3
Balsamic vinegar contains sugar. Sometimes a lot of sugar. The mold you are seeing is probably related to that, and would be very unlikely to happen on regular vinegar.
