Apple cider vinegar is a type of vinegar made from fermented apple juice. It is produced by crushing apples and extracting their liquid, which is then combined with yeast to convert the sugars into alcohol. Bacteria are then added to the mixture to ferment the alcohol into acetic acid, which gives apple cider vinegar its strong, tangy flavor and pungent aroma. This vinegar is often used in cooking, salad dressings, marinades, and as a preservative. It is also popular for its potential health benefits, including aiding digestion, supporting weight loss, and improving skin health. Apple cider vinegar is available in both filtered and unfiltered forms, with the unfiltered version containing the "mother," a cloudy substance that consists of acetic acid bacteria and proteins.
