Sparkling wines are a type of wine that contains carbon dioxide, which creates bubbles. This effervescence can occur naturally during fermentation or be added later. Common types of sparkling wines include Champagne, Prosecco, and Cava, each with unique flavors and production methods. The bubbles in sparkling wines can enhance the drinking experience, making them popular for celebrations and special occasions. They are often served chilled and can be paired with a variety of foods, from appetizers to desserts. The sweetness levels can vary, ranging from dry to sweet, catering to different taste preferences.
