Fermented beverages are drinks produced through the process of fermentation, where sugars are converted into alcohol or acids by microorganisms such as yeast and bacteria. This process not only enhances flavor and aroma but also contributes to the beverage's nutritional profile, often increasing probiotics and beneficial compounds. Common examples include kombucha, a fizzy tea enriched with probiotics; kefir, a tangy, creamy drink made from fermented milk; and various alcoholic drinks like beer, wine, and cider. These beverages are often celebrated for their unique tastes, potential health benefits, and cultural significance across different societies.
