Cider vinegar, also known as 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 subsequently into acetic acid, giving the vinegar its distinct sour taste. Cider vinegar is commonly used in cooking, salad dressings, and as a natural preservative. It is also popular in home remedies and health practices, often touted for potential benefits such as aiding digestion and supporting weight loss, although scientific evidence varies.
