Cava is a sparkling wine of denominación de origen (DO) status from Spain. It may be white (blanco) or rosé (rosado). The Macabeo, Parellada and Xarel·lo are the most popular and traditional grape varieties for producing cava. Chardonnay and Malvasia are also permitted. Authorized red grapes are Garnacha tinta, Monastrell, Trepat, and Pinot Noir. Only wines produced in the traditional method may be labelled "cava"; those produced by other processes may only be called "sparkling wines". About 95% of all cava is produced in the Penedès area in Catalonia, Spain, with the village of Sant Sadurní d'Anoia being home to many of the largest Catalan production houses. The two major producers are Codorníu and Freixenet. Cava is also produced in other villages in the provinces of Girona, Lleida, Tarragona, and Barcelona in Catalonia, Zaragoza in Aragon, Badajoz in Extremadura, La Rioja, Araba/Álava in the Basque Country, Navarra and València in the Valencian Community.

Sparkling wine is a wine with significant levels of carbon dioxide in it, making it fizzy. While it is common to refer to this as champagne, European Union countries legally reserve that word for products exclusively produced in the Champagne region of France. Sparkling wine is usually either white or rosé, but there are examples of red sparkling wines such as the Italian Brachetto, Bonarda and Lambrusco, and the Australian sparkling Shiraz. The sweetness of sparkling wine can range from very dry brut styles to sweeter doux varieties.
