Sparkling wine has effervescence - bubbles- that are the result of a secondary fermentation. This fermentation can take place in the bottle itself or in a tank, after which it is then bottled.

Sparkling wines are produced in many countries around the world; the most famous examples are from Champagne. The method used to create Champagne is known as the classic method outside this region and is used to produce bubblies such as Cava in Spain, Franciacorta and Alta Langa in Italy as well as the finest sparkling wines in countries such as the USA, New Zealand and Australia.

Sparkling wines with their bubbles are celebratory wines to be sure, but they are also among the finest food wines produced, as they can accompany a wide variety of foods. Sparkling wines range from extremely dry to very sweet and are produced in several versions from Blanc de Blancs (only white grapes) to Rosé, which have a copper, salmon or pink color.
