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. These wines are often enjoyed during celebrations and special occasions due to their festive nature. The bubbles in sparkling wines can enhance the tasting experience, making them refreshing and lively. They can be served as an aperitif or paired with various foods, adding versatility to their enjoyment.
