Champagne wine is a sparkling wine produced exclusively in the Champagne region of France. It is made primarily from three grape varieties: Chardonnay, Pinot Noir, and Pinot Meunier. The unique climate and chalky soil of the region contribute to the wine's distinct flavor and effervescence. The production of Champagne involves a secondary fermentation process, which creates its signature bubbles. This method, known as the Méthode Champenoise, requires strict adherence to regulations, ensuring that only wines meeting specific criteria can be labeled as Champagne. This makes it a prestigious and sought-after beverage worldwide.
