Aging wine is one of the most fascinating aspects of wine appreciation. While some wines are meant to be enjoyed fresh, others develop more complexity, depth, and richness over time. But how do you know which wines improve with age and which ones should be enjoyed young? In this guide, we’ll break down everything you need to know about aging wine, including the best wines to age, how aging changes wine, and why certain wines develop better over time.

Why do some wines age well?

The ability of a wine to age depends on its structure and chemical composition. The key elements that allow a wine to improve with time are:

• Acidity – Wines with higher acidity age better because acidity acts as a natural preservative.

• Tannins – Found in red wines, tannins soften over time, making the wine smoother and more complex.

• Sugar levels – Sweet wines like Sauternes and Port age exceptionally well due to their high sugar content.

• Alcohol content – Fortified wines with higher alcohol, like Sherry and Madeira, have a long aging potential.

Which wines improve with age?

Not all wines benefit from aging, but certain types are known to develop beautifully over time:

Red wines that age well

• Cabernet Sauvignon – High tannins and acidity make this one of the most age-worthy wines.

• Nebbiolo (Barolo, Barbaresco) – Develops incredible complexity, softening its powerful tannins over decades.

• Syrah/Shiraz – Gains depth with notes of leather, spice, and dark fruit over time.

• Tempranillo (Rioja Gran Reserva) – Aged Rioja develops smooth tannins, earthy flavors, and elegance.

White wines that age well

• Chardonnay (Burgundy, California) – Gains richness, nutty complexity, and creamy texture with age.

• Riesling – High acidity allows it to age for decades, developing honeyed and petrol-like aromas.

• Sémillon – Transforms beautifully, adding layers of depth and texture over time.

Sweet and fortified wines that age well

• Port – Improves for decades, developing dried fruit, caramel, and nutty notes.

• Sauternes – A legendary sweet wine that becomes richer and more complex over the years.

• Madeira & Sherry – Exceptionally long-lived, these wines can be aged for 50+ years.

How aging changes wine flavors

As wine ages, its flavors evolve:

• Fruit flavors fade – Young wines have fresh, bright fruit flavors, while aged wines develop dried fruit, nutty, or earthy notes.

• Tannins soften – Harsh tannins in young reds mellow, making the wine smoother.

• Aroma complexity increases – Aged wines develop secondary and tertiary aromas like leather, mushroom, tobacco, and spice.

How to properly age wine

1. Store at the right temperature – Keep wine between 10-15°C (50-59°F) in a stable, dark environment.

2. Avoid temperature fluctuations – Heat and sudden changes can ruin aging potential.

3. Store bottles on their side – Keeps corks moist to prevent oxidation.

4. Monitor humidity – 50-70% humidity helps preserve cork integrity.
