Wines with the best “structure” will generally age most gracefully.

Finding wines that will improve over time requires that you pay attention to a wine’s structure. What is structure? These are the primary components:

• Acidity - Wines lose acidity over time, so it’s important that the acidity be moderately high to aid as a preservative. Acidity can be detected in a wine by it mouth-watering characteristic.

• Tannin - These compounds stabilize a wine’s flavor and help maintain its color. Tannins, when young, will be detected by its astringency or mouths-drying characteristic.

• Alcohol - Acts as a stabilizer in higher amounts (e.g. fortified wines) and in some dry wines with >15% ABV). Alcohol levels are generally printed on the label. High levels of alcohol can be detected by a mild burning sensation in the throat after swallowing.

Finally, it’s the interaction of tiny amounts of oxygen in the bottle along with the acids, tannins and alcohol that produce the chemical interactions that affect how a wine ages.

But, each of these attributes must be in balance with one another. That is, in proportion to each other. And, the best way to know if a wine is balanced is by tasting it and learning to detect this overall balance.

Here are some wines that tend to have good structure that tend to be age-worthy:

• Cabernet Sauvignon

• Syrah

• Merlot

• Bordeaux Wines (which are primarily blends of Cabernet Sauvignon, Merlot and Syrah)

• Nebbiolo

• Sangiovese (the grape used in Italian Chianti)

• Tempranillo (the grape used in Spanish Rioja)

• Pinot Noir (the grape used to make red Burgundy)

• Malbec

Even with this knowledge, experienced collectors sometimes have trouble determining which wines will age and for how long. So, you’re not alone in trying to figure this out.

Again, most wines are ready for consumption as soon as they are bottle. It’s only a very small percentage of wines that are actually able to age well. And, you’ll probably need to spend $50 (US) or more to find such age-worth wines.

So, if you find a great red wine, with great structure and it’s well-balanced, try putting a few more away in proper storage, and then pull them out one at a time (every 6 to 12 months) to see how they are changing with age. Hopefully for the better! Cheers!
