To generate apple cider vinegar, apples are crushed and exposed to yeast. By carrying out this, the normal sugar from your apple is fermented after a while and turned into Alcoholic beverages (like you would probably do with wine). Sounds like building apple cider, proper? Yeah, as the approach is comparable. The main difference may be the apple cider vinegar is fermented two times –after to help make alcoholic cider as well as a 2nd time to really make it vinegar.
