Apple cider vinegar, often abbreviated as ACV, has a history that stretches back thousands of years. It all starts with the apple, one of the oldest cultivated fruits. The process of turning apples into vinegar is a tale of natural fermentation. The journey begins with apples being crushed to produce apple juice. This juice is then fermented into alcohol by natural yeasts, much like the process of making hard cider. But instead of stopping there, a second fermentation process occurs, where acetic acid bacteria convert the alcohol into acetic acid, giving us that characteristic tangy vinegar taste.
