Bordeaux Vintage Report: Understanding Your Holdings

A Bordeaux vintage report helps you decide whether to drink, hold, or sell your fine wine holdings. It gives context on the growing season and its impact on quality and longevity. Some wine writers, such as Frank J. Prial, have declared the vintage chart "dead," citing advancements in winemaking technology. The importance of vintage remains varied and disputed. That is particularly true for wines from regions at colder climatic limits of production, such as Bordeaux. Roman Weil's blind tasting study found that experienced wine drinkers could not distinguish between good and bad vintages, except for Bordeaux wines. That suggests vintage quality does matter for this region. However, even when a distinction could be made for Bordeaux, the match between tasters' assessments and vintage charts was little better than tossing a coin, according to Weil.

How does a vintage define your Bordeaux?

A vintage wine is one made from grapes that were all, or primarily, grown and harvested in a single specified year. The term "vintage" itself was first used in the early 15th century, adapted from the Old French "vendange", meaning 'wine harvest'. For wine produced in regions at the colder climatic limits of wine production, vintage can be very important. Some seasons will be much warmer and produce riper grapes and better wine. Bordeaux, situated in southwest France with an Atlantic climate, can experience significant vintage variation.

Most countries allow a vintage wine to include a portion of wine not from the year denoted on the label. In the European Union, the requirement is 85% same-year content for vintage-dated wine. In the United States this requirement is also 85%. A wine carrying an AVA designation must reach 95%. The opposite of a vintage wine is a nonvintage wine, often a blend from the produce of two or more years. That is a common practice for winemakers seeking a consistent style.

Does a vintage report accurately predict quality?

The importance assigned to vintage is both varied and disputed. Some wine writers express skepticism about the absolute reliability of vintage charts. Frank J. Prial, a New York Times wine columnist, declared the vintage chart to be "dead," stating that "winemakers of the world have rendered the vintage chart obsolete,". Bill Marsano further wrote that "winemakers now have the technology and skills to make good and even very good wines in undistinguished years." James Laube of Wine Spectator asserted that "even an average vintage can yield some grand wines."

Roman Weil is co-chairman of the Oenonomy Society of the US and a professor at the University of Chicago. He tested the hypothesis that experienced wine drinkers "cannot distinguish in blind tastings the wine of years rated high from those of years rated low, or, if they can, they do not agree with the vintage chart's preferences,". Weil's study used wines ranging from four to 17 years beyond their vintage with 240 wine drinkers. He found that tasters could not distinguish between wines of good and bad vintages except for Bordeaux wines. Even when a distinction could be made, the match between the tasters' individual assessments and the charts' rankings was little better than tossing a coin. When the tests were replicated with wine experts, including French wine academics, the results were again the same as chance.

Despite these findings, Weil does not consider a vintage chart to be useless. He suggests using one to help "find good buys in wine," as wine made in years considered to be worse than average for vintages may be priced far below its actual quality. This aligns with a common Bordelais saying: "The best vintage is the vintage we have to sell," as cited by Joshua Greene in Wine & Spirits.

How does Bordeaux's terroir influence vintage variation?

The success of winemaking in Bordeaux is largely due to its environment for growing vines. The region's geological foundation is limestone, resulting in a soil structure heavy in calcium. The Gironde estuary, along with its tributaries the Garonne and Dordogne rivers, irrigates the land and provides an Atlantic climate. These rivers define the main geographical subdivisions. Those are the "Right Bank" (around Libourne), Entre-Deux-Mers (between the Dordogne and Garonne), and the "Left Bank" (around Bordeaux, including Graves and Médoc).

The concept of terroir plays a pivotal role in Bordeaux wine production. Top estates aim to make terroir-driven wines that reflect their origin. The grapes often come from a single vineyard. The soil of Bordeaux consists of gravel, sandy stone, and clay. The region's best vineyards sit on well-drained gravel soils frequently found near the Gironde river. An old adage in Bordeaux states that the best estates can "see the river" from their vineyards. Classified estates occupy the majority of land facing riverward.

Red Bordeaux wines are generally made from a blend of grapes, with Cabernet Sauvignon, Cabernet Franc, Merlot, Petit Verdot, Malbec, and Carménère permitted. As a broad generalization, Cabernet Sauvignon is Bordeaux's second-most planted grape variety. It dominates the blend in red wines produced in the Médoc and the rest of the left bank of the Gironde estuary. Typical top-quality Châteaux blends are 70% Cabernet Sauvignon, 15% Cabernet Franc, and 15% Merlot. Conversely, Merlot tends to predominate in Saint-Émilion, Pomerol, and other right bank appellations. Typical blends from top-quality Châteaux there are 70% Merlot, 15% Cabernet Franc, and 15% Cabernet Sauvignon. This regional grape dominance, combined with specific vintage conditions, contributes significantly to the character of each year's wine.

What are the ideal storage conditions for long-term holding?

Proper storage is crucial for preserving the quality of your Bordeaux over time. The AWRI Technical Note TN09 provides guidance on the effects of heat and light on wine during storage.

• Temperature: Excessive storage temperatures significantly affect the shelf life of bottled wine. Marais (1986) observed the development of faulty flavors and decreasing overall quality after 12 months of storage at 30°C. Temperatures exceeding 40°C will induce visual and sensory changes to a wine in only a matter of days, according to Ough (1986). In general, any storage place where the temperature exceeds 25°C for long periods and 40°C for short periods can affect wine quality, Ough (1992) states. Amon and Simpson (1986) recommend storing bottled wine with the cork in contact with the wine in a cool (15-20°C), dry location. Leakage of wine or movement of cork stoppers due to thermal expansion may result from exposure to temperatures significantly greater than ambient temperature. This physical damage does not necessarily imply affected wine quality. The Institute has been unable to find literature on whether prolonged storage in a refrigerator could adversely affect wine quality due to compressor vibrations. For more on protecting your investment, consult our guide to storing wine.

• Light: Light can have deleterious effects on wine flavor. Maujean and Seguin (1983) demonstrated that 'lightstruck' flavor (goûts de lumière) is due to the formation of volatile sulfur compounds. Dozon and Noble (1989) found that exposure of still and sparkling white wines in green glass to fluorescent lamps resulted in lightstruck flavor after 31.1 hours and 18 hours, respectively. In clear glass, this occurred after only 3.3 hours and 3.4 hours. Direct sunlight provides 4286 times the amount of UV-A radiation as a 36W fluorescent lamp, according to Gordon Watson. It is likely more deleterious to wine quality than electric lighting systems. Rankine (1989) indicates that amber glass is most effective in excluding wavelengths below about 450 nm. The Institute's investigations have identified a disproportionately high number of copper instability cases in white wines stored in clear glass bottles. Those cases result in haze.

How do Bordeaux wines age compared to other fine wines?

Bordeaux wines enjoy a reputation for aging potential. Their characteristics differ from other long-lived fortified wines like Port, Madeira, and Sherry. Understanding these differences can inform your decisions on when to open or sell your bottles.

Wine Type	Primary Aging Method	Typical Longevity (Sealed)	Post-Opening Durability	Vintage Declaration
Bordeaux	Barrique aging (commonly a year), then bottle aging	Long-lived on both banks, most classed-growth reds meant to be cellared before drinking, while Bordeaux AOC wines are made in a style meant to be drunk young (Bordeaux wine)	Shorter than a fortified wine, since port generally lasts longer once opened than unfortified wine does (Port wine)	Yes, for specific years
Vintage Port	Barrels/stainless steel (max 2.5 years), then bottle aging	10-40+ years, even decades/centuries for fine examples (Port wine)	Several days (old), weeks/months (young Ruby) (Port wine)	Yes, declared by individual houses in best years (Port wine)
Madeira	Estufagem (artificial heat) or Canteiro (natural heat)	Decades to centuries, 200+ years for some (Madeira wine)	Months or longer, decades for vintage Madeira (Madeira wine)	Yes, but "Vintage" term is trademarked by Port traders in Portugal (Madeira wine)
Sherry	Solera system (blending vintages)	Years for oxidatively aged, generally no further benefit once bottled (Sherry)	Fino/Manzanilla: soon after opening (same day); Amontillado/Oloroso: longer; Sweet: weeks/months (Sherry)	No, usually no specific vintage year (Sherry)

Bordeaux wines typically spend a period in 225-litre oak barriques, commonly a year. Bottling and further aging follow before release. Vintage Port, in contrast, spends a maximum of two and a half years in barrels or stainless steel before bottling. It is then designed to age another 10 to 40+ years in the bottle. Particularly fine examples gain complexity for many decades. The oldest known vintage port still available as of 2018 is the 1815 Ferreira. Vintage Port accounts for only about two percent of overall port production. Not every year is declared a vintage in the Douro. Each individual port house makes that decision early in the second year following the harvest.

Madeira wines stand out for their unique winemaking process, which oxidizes the wine through heat and aging. Wines produced by the canteiro method can survive for decades and even centuries, even after being opened. Madeira is exceptionally durable after opening. Good examples remain sound for months or longer. Vintage or Frasqueira Madeira must age at least 19 years in a cask and one year in bottle. It cannot be sold until it is at least 20 years of age. The word "vintage" does not appear on bottles of vintage Madeira. In Portugal, it is a trademark belonging to the Port traders. Madeira's exceptional longevity and stability drive its investment market. Rare vintage bottles command significant premiums.

A solera system ages and blends sherry wines. Bottles therefore usually do not carry a specific vintage year. They can contain a small proportion of very old wine. Sherry matures in the solera for a minimum of two years. Once bottled, sherry generally does not benefit from further aging, and you can drink it immediately. Oxidatively aged sherries keep for years without noticeable flavor loss. Fino and Manzanilla are the most fragile types and should be drunk soon after opening. Sweeter versions can last several weeks or even months, because their sugar content acts as a preservative.

What are the current market trends affecting Bordeaux?

A range of factors influences the market for Bordeaux wines, from global consumption patterns to regional vineyard changes. In February 2009, market reports showed that buying power had increased by 128%. Prices for the very best Bordeaux wines had been lowered. Top Bordeaux wines are primarily sold by receiving payment in advance, a practice known as selling en primeur. Bordeaux wines tend to be the most common at wine auctions. That comes down to their combination of longevity, fairly large production, and established reputation.

However, several factors were reducing Bordeaux demand as of 2025. They include wider availability of other wines and generational differences in alcohol consumption. The trend towards "janvier sec," or January without wine, is also responsible for declining sales, in addition to general health recommendations. In 2024, the area under vine in Bordeaux fell from 103,000 hectares to 95,000 hectares. This regional decline reflects a broader trend. World alcohol consumption per capita reduced from 5.7 litres in 2010 to 5.5 litres in 2019. Stay informed on the broader market with our live fine wine market index.
