Sparkling wine is any wine that is carbonated. This makes the wine bubbly. These wines are often enjoyed during celebrations and events. They are also great with food or on their own. 

Winemakers can make their wine bubbly by a few different methods. In many styles, such as Prosecco, winemakers use a special tank to create bubbles from a secondary fermentation. 

The most famous is the traditional method. This popular method was invented in Champagne. For the traditional method, winemakers add a small amount of yeast and sugar into their fermented wine after it’s been bottled. The yeasts eat the sugars and create a small amount of alcohol and carbon dioxide, CO2. The winemaker then seals the bottle with a cork, trapping the gas and forming bubbles in the wine.
