Prosecco is a typical Italian white wine — generally a Dry or Extra Dry sparkling wine — normally made from Glera ("Prosecco") grapes.
Prosecco is protected as a DOC within Italy, such as Prosecco di Conegliano-Valdobbiadene, Prosecco di Conegliano and Prosecco di Valdobbiadene
Prosecco DOC is produced in the regions of Veneto and Friuli Venezia Giulia in Italy, and traditionally mainly in the areas near Conegliano and Valdobbiadene, in the north hills of Treviso.
Prosecco is mainly produced as a sparkling wine in either the fully sparkling (spumante) or lightly sparkling (frizzante, gentile) varieties.
In Italy, Prosecco is enjoyed as a wine for every occasion. Outside Italy, it is most often drunk as an aperitif, much like Champagne. Like other sparkling wines, Prosecco is served chilled.
Most commonly Prosecco is served unmixed, but it also appears in several mixed drinks.
Wines from the traditional Conegliano–Valdobbiadene production area are labeled as "Prosecco di Conegliano-Valdobbiadene", "Prosecco di Conegliano" or "Prosecco di Valdobbiadene" or "Prosecco DOC" from Friuli. Proseccos labeled with a non-protected designation, such as "IGT-Veneto", are generally cheaper and having a more varied quality.
There are different kind of sweetness in the Spumante version
Extra-Brut or Brut-Naturale 0-6 gram of sugar per liter (the driest of the dry, unsweetened)
Brut less than 15 gram of sugar per liter (dry, this is the typical style of Champagne with no sweetness)
Extra-Dry 12-20 gram of sugar per liter (still dry with a hint of sweetness or slightly sweet)
Sec 17-35 gram of sugar per liter (medium sweet)
Demi-Sec 33-55 gram of sugar per liter (sweet)
Doux more than 55 gram of sugar per liter (Sweetest, very rare and is considered as dessert wine)
