Sparkling wine comes in various styles, each defined by region, grape varieties, and production methods. Champagne, from France, is the most renowned, made primarily from Chardonnay, Pinot Noir, and Pinot Meunier using the traditional method. Prosecco, from Italy, is lighter and fruitier, produced via the Charmat method. Spain's Cava also uses the traditional method but features native grapes like Macabeo, Parellada, and Xarel-lo. Crémant offers regional French sparkling alternatives. Lastly, pét-nat (pétillant naturel) is a rustic, naturally sparkling wine created using the ancestral method, offering a raw, unfiltered charm.
