“How long should I age this wine?” and “Should I age this wine?” are questions we are often asked. These are complicated questions that vary greatly from wine to wine and vintage to vintage so we decided to spend some time and break it all down for you!
There are a number of important factors at play when it comes to ageability—the quality of the vintage (or year the grapes were harvested), the production practices, vineyard practices, the region where the grapes were grown, and of course the grape itself. For simplicity purposes, let’s focus on which grape qualities help make a wine age-worthy. In no certain order they are: alcohol, sugar, tannin and acid. To age well, a wine must possess one or more of these factors, and be balanced (meaning not one of these elements stands out against the others). That $5 bottle of sweet red wine on the supermarket shelf just won’t cut it.
Alcohol & Sugar
Alcohol and sugar both serve as preservatives that can help a wine last longer. The general rule is: the higher the alcohol and sweetness, the longer the wine will age. In other words, the “bigger” or “fuller” the wine, the longer you can cellar it. Wines that have been fortified with a neutral grape spirit, such as Port (which also has high sugar levels on its side), can age for many years when made well – 10 or even 20 years! Similarly, high quality dessert wines like French Sauternes with ample residual sugar can be cellared for decades.
Tannins
In red wines, high concentrations of tannins and flavor compounds are the keys to longevity. Over time a wine with strong tannins (mouth drying, bitter compounds) will soften and become smoother. The fruit flavors will also dissipate and give way to more nuanced flavors that become earthier (think mushroom and truffle). The tannins and flavor compounds eventually precipitate out of the wine forming sediment, which is why older wines are often decanted. Examples of wines with high concentrations of these compounds are Cabernet Sauvignon and Syrah. They, too, can often age for 10-20 years plus!
Acid
Acid is another great preservative in wine and is the key for aging white wines and certain reds like Pinot Noir. As the years pass, the acids and alcohol in the wine interact to form chemical compounds that create new aromas. This process adds more complexity to the wine over time. While the acidity levels do not change, the perception of acidity becomes less pronounced. An example of a white wine that might benefit from bottle age is high acid, premium quality Riesling, which can typically age well for 5-10 years.
The Takeaways
Like we always say in the tasting room, wine preference is subjective, it all comes down to what you like. All of our Reserve red wines will age well for a number of years, but you may enjoy them more upon release if you prefer bright and fruit driven wines. If your preference is softer wines with a little more spice or earthiness, then age away. Our whites, on the other hand, are purposely made to be drunk young and are released at optimal drinking time, that being said, Chardonnay, Sauvignon Blanc and even Pinot Blanc (often a surprise for guests) can all be aged nicely for a handful of years. My rule of thumb (when I can afford it) is to buy two bottles and see if I can tell the difference after a few years of cellar time. Finally, a good stat to keep in mind is that only 10% of wines produced improve after one year of aging. That means 90% of wines will never be “too young.” So when in doubt, stop thinking about it, pop that cork (or screwcap) and enjoy!
