How do you know if apple cider vinegar is pasteurized or not?

To determine if Apple cider vinegar is pasteurized, check the label for indications such as "raw" or "unfiltered," which typically means it is unpasteurized. If the label states "pasteurized," it has undergone heat treatment to kill bacteria. Additionally, unfiltered Apple cider vinegar often contains the "mother," a cloudy substance that indicates it has not been pasteurized. If you're unsure, you can also contact the manufacturer for clarification.
