Sparkling Non Vintage (NV) come from wine that is not made from the crop of a single identified district in a good year. Please note that "non-vintage blends are not necessarily inferior".

In comparison to Sparkling Vintage where harvests from a single year that are not blended with other years are referred to as “vintage”, showing the year of production on the label. Vintage wines, particularly from years when growing and harvesting conditions produced exceptional wines, are seen as premium, but there are many high-quality non-vintage (NV) wines too.
