supports: Sparkling wine is a wine with significant levels of carbon dioxide in it, making it fizzy. The best known example of a sparkling wine is champagne, which is exclusively produced in the Champagne region of France. Most sparkling wine is white or rosé but there are examples of red sparkling wines such as the Italian Brachetto, Australian sparkling Shiraz, and Azerbaijani "Pearl of Azerbaijan" made from Madrasa grapes. The sweetness of sparkling wine can range from very dry "brut" styles to sweeter "doux" varieties (from the French words for 'raw' and 'sweet', respectively). Brachetto is a red Italian wine grape variety grown predominantly in the Piedmont region of northwest Italy. At one time the grape was thought to be related to the French wine grape Braquet, but recent thought among ampelographers is that the two are distinct varieties. In Italys region of Piedmont the grape is somewhat more widespread: production mostly falling within an area of the provinces of Asti and Alessandria between the rivers Bormida and Belbo plus various parts of the province of Cuneo. At Canelli, on the border between the hills of Asti and the Langhe proper, the grape is known as Borgogna. The most notable wine here is the red Brachetto d'Acqui "Denominazione di Origine Controllata e Garantita" (DOCG) which is made in both still and "spumante" (fully sparkling) versions. The Piemonte Brachetto "Denominazione di Origine Controllata" (DOC), also a red wine, is made with a minimum of 85% Brachetto; it is usually still, but may be "frizzante" (lightly sparkling). The grape is also used for up to 10% of the blend for the Ruché-based Ruché di Castagnole Monferrato DOC. Prosecco ( / prsko , pro - / , Italian : ( prosekko ) ) is an Italian white wine . Prosecco DOC can be Spumante sparkling wine , Frizzante ( semi-sparkling ) , or Tranquillo ( still ) , depending on the perlage . It is made from Glera grapes , formerly known also as Prosecco , but other grape varieties may be included . The following varieties are traditionally used with Glera up to a maximum of 15 % of the total : Verdiso , Bianchetta Trevigiana , Perera , Glera lunga , Chardonnay , Pinot Bianco , Pinot Grigio and Pinot Nero . The name is derived from that of the Italian village of Prosecco near Trieste , where the grape may have originated . Prosecco DOC is produced from nine provinces spanning the Veneto and Friuli Venezia Giulia regions . Prosecco Superiore DOCG comes in two varieties : Prosecco Conegliano Valdobbiadene Superiore DOCG , which can only be made in the Treviso province of Veneto on the hills between the towns of Conegliano and Valdobbiadene ( north of Treviso ) , and the smaller Asolo Prosecco Superiore DOCG , produced near the town of Asolo . Prosecco is the main ingredient of the Bellini cocktail and can be a less expensive substitute for Champagne .
