What Is Apple Cider Vinegar?

This Type of Vinegar Is Made by Fermenting Fresh Apple Juice. During Fermentation, Yeast and Bacteria Are Added to the Juice to Turn the Fruit’s Sugars into Alcohol.

Afterwards, the Vinegar Is Either Filtered to Remove the Sediment and Bacteria Cluster (Also Called a “Mother”), or It’s Left Unfiltered and Then Bottled.
