Sparkling wine is a style of wine that contains bubbles of carbon dioxide, created either naturally through fermentation or artificially through carbonation. The most famous sparkling wine is Champagne, which must come from the Champagne region of France and follow strict traditional methods. Other regions produce excellent sparkling wines as well, such as Cava from Spain, Prosecco from Italy, and sparkling wines from California, Oregon, and beyond. There are different production methods, with the traditional method (méthode champenoise) involving secondary fermentation in the bottle, while tank methods like Charmat are used for fresher, fruitier styles like Prosecco. Sparkling wines can range from dry (Brut) to sweet (Doux) and are made from a variety of grapes including Chardonnay, Pinot Noir, and Glera. Celebrated for their lively effervescence and versatility, they pair beautifully with everything from oysters and fried foods to popcorn and dessert.
