Non-vintage (NV) sparkling wine is a blend of wines from multiple vintages, allowing producers to create a consistent house style year after year. This approach contrasts with vintage wines, which are made solely from grapes harvested in a specific year.

NV sparkling wines typically emphasise a balance of fruitiness, acidity, and complexity, and represent the producer's signature taste, unconstrained by the variations of a single vintage. The majority of Champagne produced is non-vintage.
