Why does my vinegar has stuff floating in it?
Furthermore, why does my apple cider vinegar have stuff floating in it?
The truth in Apple Cider Vinegar is not in the regular vinegar itself because it is not a clear liquid. This vinegar has brown pieces floating in it. These floating pieces are called “mother”. This is formed from the apple residue and pectin.
Beside above, how do you know when vinegar goes bad?
After some time of storing vinegar you might notice some sediment on the bottom of the bottle or the liquid starting to get cloudy. That's perfectly normal and not harmless to the vinegar at all. To get rid of that you should simply filter the vinegar before using it.
Apple cider vinegar with the mother is simply unrefined, unpasteurized and unfiltered ACV. The “mother” is a colony of beneficial bacteria, similar to a Kombucha SCOBY, that helps create vinegar through a secondary fermentation process. Vinegar is high in acetic acid and other beneficial compounds.
