Apple cider vinegar is a type of vinegar made from fermented apple juice. It is produced by crushing apples and squeezing out the juice, which is then fermented by adding yeast and bacteria. This process converts the sugars in the juice into alcohol, and then into acetic acid, giving the vinegar its distinct sour taste and strong aroma. Many people use apple cider vinegar in cooking, as a salad dressing, or as a natural preservative. It is also popular in home remedies, with claims that it can aid digestion, support weight loss, and improve skin health, although scientific evidence for these benefits varies.
