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.



enter image description here



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.

  • what I have looks very similar to that photo; The vinegar is a supermarket item, do they sell them unfiltered (like a Trappist beer for example)? Does that also mean that what is on the top of the bottle is not mold? it looks white and hairy

  • Mold can grow at the surface of the vinegar and on the bottle. Everything I've read is that it's harmless and you can just wipe it off. Undistilled, unpasteurized, vinegar of any kind can eventually form a mother. Unfiltered vinegar may already have some of the mother in the bottle. Added to answer.
