Why the same wine tastes different from one vintage to the next

What a vintage is

Look at the front or back label of most bottles and you will find a year. The vintage is the year the grapes were harvested. A bottle marked 2022 contains wine made from grapes picked in 2022, or at least a high minimum share of them, depending on local rules.

Because grapes are a crop, every year is different. Rainfall, sunshine, temperature and timing all change the fruit. A winemaker can do a great deal in the winery, but cannot fully undo what the season did. Our guide to how wine is made shows where the grape ends and the winemaker begins.

How weather changes the grape

• Warmth and sun. A warm, sunny season gives riper grapes with more sugar, softer acidity and riper fruit flavours. The wine is often fuller and higher in alcohol.
• A cool season. Grapes ripen less. The wine is lighter, fresher and higher in acidity, sometimes with green or herbal notes.
• Rain near harvest. Berries swell with water and flavour dilutes. Rot can spread, forcing early or selective picking.
• Frost, hail and heatwaves. Frost at bud break or hail in summer can cut the crop sharply. Extreme heat can shut vines down or scorch fruit.

Our guide to sweetness, acidity and tannin in wine explains how these changes show up in the glass.

Why vintage matters more in some places

In cool, marginal regions such as Burgundy, Bordeaux, Champagne or Germany, grapes only just ripen in an average year. A cool or wet season can make a big difference, which is why vintage charts and vintage talk grew up there.

In warmer, more stable climates, grapes ripen reliably most years, so differences are often smaller. That is part of the classic contrast between Old World and New World wine described in our Old World versus New World guide. It is a generalisation, though. Warm regions have difficult years too, especially with droughts, wildfires and heatwaves.

Vintage in India

Indian wine grapes are pruned for fruit after the monsoon and harvested in the dry season, usually from January to March. That timing avoids the worst of the rain, but each season still differs.

• Unseasonal rain or hail in February or March can split berries and spread rot just before harvest.
• An early heat spike can push sugar up quickly while acidity drops, so grapes must be picked fast.
• A cooler, longer winter lets grapes ripen more slowly, often giving better balanced fruit.

Our guide to wine harvest and vintage planning describes how Indian wineries plan around that window.

What the winemaker does with a difficult year

A winemaker has tools to work with each vintage, within the rules of their region.

• Selecting fruit. Sorting out damaged or rotten grapes, sometimes by hand on a sorting table.
• Adjusting the wine. Adding acid in a hot year, where allowed, or adjusting sugar in a cool one.
• Changing the style. Shorter maceration or less new oak for a lighter vintage, so the wine does not taste over-extracted.
• Blending. Combining lots or, for non-vintage wines, blending years to smooth out the differences.

Every one of these choices is a judgement made under time pressure, often while fruit is still arriving at the winery. In a strong year the winemaker's job is mostly not to get in the way. In a difficult one, skill shows.

Non-vintage wines and what to look for

Many everyday wines and most Champagne and sparkling wines are non-vintage. They blend several years to keep a consistent house style. Big wine brands value consistency, so vintage differences are small by design.

For most everyday drinking, vintage matters less than producer and storage. A good producer in a difficult year often makes better wine than a careless one in a great year. Storage counts too, because a bottle from a great vintage that has been cooked in a hot shop will taste worse than a well-kept bottle from an ordinary year.

Tasting the same wine across two or three vintages side by side is one of the best ways to understand how weather and winemaking interact. It shows exactly what a season can do.
