Sour beverages are drinks that have a tangy or acidic taste, often due to the presence of ingredients like citrus fruits, vinegar, or fermented products. Common examples include lemonade, kombucha, and sour beers. These drinks can be refreshing and are often enjoyed for their unique flavor profiles. The sour taste in these beverages is typically a result of organic acids, such as citric acid in lemons or acetic acid in vinegar. Sour beverages can also be beneficial for digestion and hydration, making them popular choices in various cultures around the world.
