Prosecco DOC refers to a category of sparkling wines from the Veneto and Friuli regions in northern Italy. The wines are either made in a frizzante or fully sparkling style. Wines can be of varying sweetness levels, ranging from Brut to Extra Dry to Demi-Sec and Sec (from driest to sweetest). The DOC regulations were changed in 2009 to recognize the examples of Prosecco from the the communes of Conegliano-Valdobbiadene; these wines were designated as DOCG, while other examples of Prosecco are DOC, as long as they conform to these particular standards.
