NV or non-vintage Champagne is a blend of wines from multiple vintages. In producing non-vintage Champagne, winemakers strive to keep the taste consistent year by year, and non-vintage wine provides flexibility in blending, ensuring a constant style each year. Non-vintage Champagne is released when it is ready, so it should be drank within a year or two after the purchase. That said, there are some stars of non-vintage that are as good as many vintage bottlings and can last a few more years.
