What Are the Characteristics of Aged Wines?

An aged wine, or a long-aging wine, is a wine that can be kept for many years with the goal of developing its aromatic profile. Under proper storage conditions, a wine with strong aging potential can be kept for many years, sometimes over 20 years, to soften its tannins (in the case of red wines) and develop highly sought-after tertiary aromas for their complexity (both white and red wines). However, not all wines age well, and in some cases, too long of an aging period can lead to the decline of the wine. To stock your cellar with aging wines, look for wines with high acidity and powerful tannins for reds, and wines with high acidity and significant residual sugars for whites. How can you identify these aging wines to open a bottle in several years?

What is an age-worthy wine?

An age-worthy wine, also known as a cellaring wine, is a wine that has the ability to improve over time. Unlike wines meant to be enjoyed young, these cuvées are crafted, vinified, and aged to evolve favorably over several years, or even decades. Wines suitable for medium ageing can be kept for 5 to 10 years, while long-ageing wines can mature for 10 to 30 years or more, depending on their style. Their structure, balance, and concentration allow them to develop complex and subtle tertiary aromas over time, leather, forest floor, truffle, candied fruit, tobacco, honey, or spices.

Not all wines are made to age. Only certain red or white wines with a solid framework, acidity, tannins, sugar, and substance, can withstand long-term ageing. While prestigious wines with higher prices are often age-worthy, some appellations such as AOC Ventoux or AOC Madiran also offer excellent cellar-worthy bottles at more affordable prices.

The essential criteria for a wine that ages well

The Grape Variety

The first variable to consider is naturally the grape variety used. For red wines, grape varieties rich in tannins and acidity will have a greater tendency to age well. Varieties such as Cabernet Sauvignon, Syrah, Malbec, and Tannat have thick skins rich in flavors and tannins. On the other hand, Pinot Noir, Gamay, and Cinsault have smoother tannic structures and are generally less suitable for aging. For white wines, look for high acidity coupled with aromatic richness. Chardonnay and Sauvignon Blanc are among the most renowned aging grape varieties. Grape varieties with high sugar content can also age well, such as Riesling or Chenin Blanc, with sugar acting as a preservative.

The Terroir

However, great Burgundy red wines, which are made from Pinot Noir, have excellent aging potential. Other factors are therefore important, with terroir and specifically the soils being crucial. The denser the soil, the more concentrated the water and nutrients will be. Vines can then nourish themselves more intensely, which is reflected in the tannin and sugar content of the grapes. Clay, limestone, or clay-limestone soils are known for producing round, supple, and powerful wines with body, making them more suitable for aging. In contrast, lighter soils, called siliceous and composed of gravel, sand, or granite sands, for example, filter more water and produce finer, airier wines that are more suited for quick consumption. Additionally, the slope of the land will also impact the wine, as water tends to accumulate more in mid-slopes, offering better aging potential.

The Vintage

Not every year is the same. In the wine market, good vintages are often sold at a premium precisely for this reason. They have the ability to age well and offer a complex taste to wine enthusiasts, and an interesting profit for wine investors. A good vintage is a year where the weather and climate were ideal for the vine. A great year starts in winter, where the cold should be sufficient to allow the vine to regenerate away from parasites but not too extreme to avoid frost. Spring should then be mild and sunny to nourish the vine's growth and flowering, with measured rainfall. Summer should provide the necessary sunshine to nourish the vine through photosynthesis and supply the fruit with the needed sugars. Finally, autumn rains should be reasonable to allow for harvesting without the risk of mold. This helps to understand why a good vintage is worth its weight in gold!

The Winemaker's Craft

Wine is a collaborative effort between man and nature. The winemaker's role is crucial in producing aging wines. Once the grapes are harvested, the winemaking methods used will influence whether the wine is suitable for aging. The first important step is fermentation, the process where grapes ferment in their juice. The longer the grapes are left in contact with the juice, the more robust the tannic structure extracted from the berries will be, which is favorable for aging. Conversely, a short fermentation will result in a fresh, light wine meant for immediate consumption.

Then, the same rule applies to aging. The longer the wine is aged, the more resistant it will be over time. This is even more true when aging occurs in wooden barrels, as the wine is exposed to wood tannins and oxidation. This makes the wine more resistant and tannic, allowing it to age and develop complex aromas. Finally, the addition of sulfites, controversial with the rise of organic and natural wines, also helps to strengthen the wine, allowing for a longer shelf life.

How to store an age-worthy wine properly

A wine only improves if it’s kept under optimal conditions. Storing it in a proper ageing wine cellar is essential for its development. The cellar should maintain a stable temperature (around 12-13°C), adequate humidity (between 70 and 80%), constant darkness, and clean air (free of strong odors). Avoid vibrations, UV light, and temperature fluctuations. Lay bottles horizontally if they’re sealed with a cork to prevent it from drying out. The cellar’s location, absence of nearby chemicals, and good ventilation are all key factors in successful ageing.

Large formats, such as magnums or jeroboams, are particularly suited for ageing, as the wine-to-oxygen ratio is smaller, which slows the wine’s evolution. It’s also essential to monitor the wine’s progress over time. Remember: the goal isn’t to keep a wine as long as possible, but to enjoy it when it reaches its peak. Don’t hesitate to rely on professional recommendations, tasting guides (like Le Guide Hachette des Vins), or expert reviewers such as Jeb Dunnuck to determine the ideal drinking window.

How to recognize an age-worthy wine when buying

Telling the difference between a true cellaring wine and one meant for early drinking requires some experience, but several clues can help guide your choice. First, the appellation. Certain regions are historically known for producing long-lived wines. Among the most notable age-worthy reds are:

• Bordeaux Grand Cru Classé wines, particularly First Growths from the Médoc in outstanding vintages, which can evolve beautifully for over 30 years.
• Burgundy Grands Crus, such as Clos Vougeot Grand Cru or Chambertin Grand Cru.
• Sweet or oxidative white wines, like Vin Jaune, can age for over 30 years thanks to their sugar, acidity, and natural oxidation.
• International examples, such as those from California’s Napa Valley, including the legendary Opus One.

For dry white wines, great German or Alsatian Rieslings and top-tier white Burgundies can also age gracefully. Key indicators to look for include the vintage, the mention Vieilles Vignes (old vines, which yield more concentrated grapes), and controlled yields, all signs of a wine built for longevity.

FAQ - Ageing wines

How long can you keep an age-worthy wine?

It depends on its structure. Medium-ageing wines keep for 5 to 10 years, while long-ageing wines can mature for 10 to 30 years or more. The aim is not to store a wine as long as possible, but to open it when it reaches its peak.

Which grape varieties make the best age-worthy wines?

For reds, choose varieties rich in tannins such as Cabernet Sauvignon, Syrah, Malbec or Tannat. For whites, look for acidity and aromatic richness: Chardonnay, Sauvignon Blanc, or sugar-rich grapes like Riesling and Chenin Blanc, where the sugar acts as a preservative.

How can you recognise an age-worthy wine when buying?

Start with the appellation: Bordeaux Grand Cru Classé, Burgundy Grands Crus, sweet whites or Vin Jaune are known for their longevity. Also check the vintage, the mention Vieilles Vignes and controlled yields, all signs of a wine built to last.

At what temperature should you store an age-worthy wine?

Keep your bottles somewhere with a stable temperature, around 12-13°C, with 70 to 80% humidity, away from light and vibrations. Lay down bottles sealed with a cork so it does not dry out.

Can every wine be aged?

No. Only wines with a solid framework of acidity, tannins and sometimes sugar can withstand long ageing. Others are best enjoyed young, and keeping them too long eventually leads to their decline.
