The harvest year — and therefore the specific growing season conditions (weather, temperature, rainfall) that affected grape quality and character.
Growing season weather differs year to year. A dry summer followed by clean harvest conditions can produce exceptional fruit; rain at harvest or disease pressure reduces quality and quantity.
Wines labelled NV (non-vintage) or without a year are blended across multiple years for consistency. Common in Champagne, Sherry and some Ports.
EU rules require wines labelled with a vintage to use at least 85% grapes from that year. Some countries permit 100% single-year labelling only.
Why the same wine tastes different in different years
Grapes are an agricultural crop. The character of any given year's harvest is shaped by temperature during the growing season, rainfall timing and quantity, disease pressure, and harvest weather. A dry summer concentrates sugars and reduces yields; August rain can dilute flavour and encourage rot. Clean, dry harvest conditions allow growers to wait for full phenolic ripeness; wet conditions force early picking. The result is that the same producer, vineyard and method can produce wines of noticeably different character year to year.
Terroir — the stable, site-specific factors (soil, topography, aspect) — remains constant. Vintage is the annual variable layered on top. In a warm, well-drained Grand Cru vineyard, terroir tends to assert itself even in difficult years; in a less well-situated plot, a poor vintage is more damaging. For how 2026 played out in Burgundy specifically, see the Burgundy 2026 harvest report.
When vintage does and does not matter
For everyday wines — supermarket Sauvignon Blanc, entry-level Prosecco, branded Chianti — vintage is largely irrelevant. These wines are produced for consistency and drunk young. For fine wine from quality-sensitive regions, vintage matters increasingly as you move up the quality pyramid. Burgundy Grand Cru from a great year (2019, 2015, 2010) versus a difficult year (2017, 2013) can differ significantly in both quality and market price. Bordeaux en primeur pricing is driven partly by vintage quality assessments — see the Bordeaux 2025 en primeur report for a live example.
The year on the label also tells you approximately how old the wine is, which matters for storage and drinking windows. Most still wines are intended to be drunk within 5 years of vintage; structured reds and fine whites within their producer's stated window. The How to read a wine label guide covers how to find the vintage on different label formats.
Wine vintage meaning and what makes a wine a vintage
The wine vintage — the year printed on a wine label — represents the harvest year and therefore the specific growing season conditions that shaped the grapes. The vintage wine meaning is straightforward: a wine labelled with a single year was made predominantly (at least 85% under EU rules) from grapes harvested in that year. What makes a wine a vintage, colloquially, is that it carries a year on the label and reflects the conditions of a specific growing season — as opposed to non-vintage (NV) wines, which blend multiple harvests for consistency. Understanding vintage is most valuable for fine wine from climate-sensitive regions, where year-to-year weather variation produces meaningfully different wines. Decanter and Jancis Robinson both publish detailed vintage charts and annual quality assessments for major wine regions.
