If a wine or a Champagne is done with more than a vintage (to say that it is a cut of wines of different vintages), it is called "non–vintage", since the majority is not necessarily composed of a single vintage. We read this expression in many bottles of Champagne, since about 80 to 90% of Champagnes are made with a blend of three or more wines of various vintages. NV wines are created to allow the winemaker to make a type of wine which corresponds to the expectations of loyal consumers. In Champagne this is called house style. The manufacturers often cut a vintage with another wine outside the economic or market need. Many dessert wines like Sherry are NV cuts, too.
