Vintage Champagne (Millésimé / Vintage) — Champagne produced from grapes from a single harvest year, which is indicated on the label. A vintage is chosen to express the distinctive characteristics of a particular harvest.
Non-Vintage Champagne (Non-Millésimé / NV) — Champagne produced from grapes from multiple harvest years. Blending different years allows the producer to maintain a consistent house style from year to year.
