Champagne and sparkling wine are both festive drinks, but they have some important differences. Champagne comes from the Champagne region of France, while sparkling wine encompasses a variety of sparkling wines from different parts of the world. The major difference between the two is in the way they are produced. Champagne is usually made by 'méthode champenoise' which is an expensive and labor-intensive process. On the other hand, sparkling wine is made following the 'tank method.'

Champagne is made from several grapes, including pinot noir, pinot meunier, and chardonnay. Sparkling wine, on the other hand, is made from a variety of grape varietals depending on the region. The flavor and character of each type will vary depending on the grape variety and winemaking process used.

Another difference between champagne and sparkling wine is the price. Because of the labor and production costs associated with making champagne, the price is generally more expensive than the price for sparkling wines. While champagne can range in price depending on the brand, sparkling wines are usually available at a lower price-point. However, both offer a luxurious, celebratory drink for any occasion.
