Which Champagne style is made from grapes harvested in a single vintage year?

Vintage Champagne is made from grapes harvested in a single vintage year.

A producer declares a vintage only when the harvest is considered suitable for a wine with that year’s character. The resulting Champagne must identify the harvest year on its label and is not blended across multiple harvests in the usual non-vintage manner. Vintage wines generally receive longer maturation before release.

Non-vintage Champagne, by contrast, combines wines from different years to create a consistent house style. “Vintage” therefore describes the harvest source, not simply the age of a bottle. A vintage Champagne can be young when released, while a non-vintage bottle can include older reserve wines.

Rosé is a color style, and blanc de blancs describes a Champagne made from white grapes. Neither term automatically indicates a single harvest year, so they are separate categories from vintage designation.
