Sherry, a renowned fortified wine from Spain, is beloved for its versatility, depth of flavor, and historical significance. Whether sipped as an aperitif, paired with a meal, or used in cooking, sherry has a unique charm that sets it apart from other wines. However, as with any fine wine, a common question arises: does sherry wine go bad?
The answer, like most things in the world of wine, is a bit nuanced. Sherry, being a fortified wine, has certain characteristics that make it more durable than many other wines. However, just like any wine, improper storage, exposure to air, or even age can affect its quality. In this article, we will explore whether sherry goes bad, how to store it properly, how long it lasts, and how to recognize signs that it may have gone off. Additionally, we will examine the different styles of sherry and how each one might age over time, providing a deeper understanding of this fascinating wine.
What Is Sherry?
Sherry is a fortified wine made primarily in the Jerez de la Frontera region of southern Spain. It is produced using specific grape varieties, such as Palomino, Pedro Ximénez, and Muscat of Alexandria. The unique process of fortification, where additional alcohol is added to the wine, contributes to its distinct characteristics and enhances its ability to withstand aging.
Sherry can be dry or sweet, light or rich, and pale or dark. There are various styles of sherry, including Fino, Manzanilla, Amontillado, Oloroso, and Pedro Ximénez. These wines are aged in barrels using a technique known as the Solera system, a fractional blending method that ensures consistency and complexity over time.
Given its fortification, sherry is often thought to be immune to the typical fate of regular wines, which can spoil or turn sour after opening. But is this really the case?
The Lifespan of Sherry Wine
One of the key factors in understanding whether sherry goes bad is knowing the wine’s composition. Sherry differs from regular wines in several ways, and these differences affect its longevity:
1. Fortification
Sherry is fortified with a distilled grape spirit (aguardiente), which increases its alcohol content, typically to around 15-20%. This additional alcohol helps preserve the wine and makes it more stable over time, both before and after opening. Fortification helps prevent spoilage by reducing the chances of microbial activity, which is the primary cause of wine spoilage in non-fortified wines.
2. Oxidation Resistance
Sherry also undergoes a unique aging process where some styles are aged in contact with oxygen (especially Oloroso and Amontillado), which gives them greater resistance to oxidation. This process alters the chemical structure of the wine, making it more resilient to the effects of air exposure compared to other wines.
3. The Solera System
The Solera system used in sherry production is another factor that contributes to its longevity. It creates a stable, consistent product by blending older and younger wines over time, and it helps maintain a high-quality, reliable product. Wines produced through this system generally have a longer shelf life.
So, how does all this affect the wine’s longevity? The answer depends on the type of sherry.
Does Sherry Go Bad After Opening?
While sherry is more resilient than non-fortified wines, it can still go bad, especially if not stored properly after opening. The effects of oxygen, light, temperature, and time all play a role in how sherry ages after being uncorked. Here’s a breakdown of what happens to different types of sherry after opening:
1. Fino and Manzanilla
Fino and Manzanilla are the driest styles of sherry, often consumed as refreshing, light aperitifs. These wines are aged under a layer of yeast known as flor, which protects the wine from oxidation during its aging process. However, once the bottle is opened, the flor begins to dissipate, and the wine is no longer protected from oxygen.
Fino and Manzanilla are best consumed within a few days to a week after opening. Once exposed to air, these wines can lose their delicate freshness and develop off-flavors. To preserve them for longer, it’s essential to store these wines in a cool, dark place with the cork tightly sealed. If you plan to store them for a longer period, it’s advisable to refrigerate them.
2. Amontillado
Amontillado is a style of sherry that starts as a Fino but undergoes additional aging after the flor dies off. This results in a wine that has more oxidative characteristics and is slightly richer, with flavors of nuts, dried fruit, and spice. While Amontillado is more resistant to oxidation than Fino or Manzanilla, it will still gradually change once opened.
Amontillado can last a bit longer than Fino, up to a few weeks after opening, depending on storage conditions. Like Fino, it should be stored in a cool, dark place, and it’s best to refrigerate it if you plan to keep it longer than a week. Over time, exposure to air will diminish the wine’s complexity and lead to a flatter, less interesting taste.
3. Oloroso
Oloroso is a rich, full-bodied style of sherry that is aged without flor, allowing it to be more resistant to oxidation. These wines are dark, complex, and often have flavors of caramel, dried fruit, and spices. Because of its higher alcohol content and oxidative aging, Oloroso is one of the longest-lasting sherries after opening.
Once opened, Oloroso can last for several weeks or even months, depending on how it’s stored. As with other sherries, it should be kept in a cool, dark place, and refrigeration can help preserve its quality for a longer period. Unlike Fino and Manzanilla, Oloroso’s flavors typically evolve and mature, so a bit of oxidation can actually enhance the wine’s character.
4. Pedro Ximénez
Pedro Ximénez (PX) is the sweetest style of sherry, made from sun-dried grapes that concentrate the sugars. It’s a rich, syrupy wine with flavors of raisins, figs, and chocolate. Due to its high sugar content and the fact that it is heavily fortified, PX is less susceptible to spoilage than drier styles.
Once opened, PX can last for months, especially if kept in a cool, dark place and sealed tightly. However, like other sweet wines, it can begin to lose its vibrancy and freshness over time. While it is more resilient than Fino or Manzanilla, it will still change, so it’s best to consume it within a few months for the best experience.
How to Store Sherry After Opening
To get the most out of your opened bottle of sherry and preserve its flavor and integrity, proper storage is key. Here are some tips for storing sherry wine:
1. Seal the Bottle Tightly
After opening the bottle, ensure the cork or screw cap is securely fastened. This will minimize the wine’s exposure to air, which is the main cause of deterioration in open bottles of sherry.
2. Store in a Cool, Dark Place
Sherry, like other wines, should be kept in a cool, dark environment. Ideally, the temperature should be between 50°F and 65°F (10°C – 18°C). Excessive heat and direct light can cause the wine to spoil more quickly, altering its flavors and aromas.
3. Refrigerate Lighter Sherries
For lighter sherries like Fino or Manzanilla, refrigeration is highly recommended. Keeping these wines in the fridge can help slow down oxidation and preserve their fresh, delicate character for a longer time.
4. Use Wine Preservation Tools
If you don’t plan to finish your bottle within a few days, consider using wine preservation tools, such as vacuum pumps or inert gas sprays, to limit air contact. These can help extend the life of your sherry.
Signs That Your Sherry Has Gone Bad
Even with the best storage practices, there are times when sherry can go bad. Here are some signs to look out for:
1. Off or Sour Smell
If the sherry has a vinegary, sour, or musty smell, it’s a sign that it has oxidized too much or gone off. These unpleasant odors indicate that the wine is no longer in good condition.
2. Flat or Lifeless Taste
A loss of flavor, or the wine tasting flat, dull, or lifeless, can indicate that the wine has been exposed to too much air. While some oxidation is beneficial for aging, too much can strip the wine of its character.
3. Change in Color
While the color of sherry will naturally evolve over time (especially darker styles like Oloroso or PX), a drastic change in color, such as a hazy or cloudy appearance, could signal spoilage.
Conclusion
In conclusion, while sherry is more durable than most wines due to its fortification and unique aging process, it can still go bad if not stored properly. Lighter styles, like Fino and Manzanilla, are best consumed soon after opening, while richer, oxidative styles like Oloroso and Pedro Ximénez can last much longer. By storing your sherry in the right conditions—cool, dark, and tightly sealed—you can extend its lifespan and continue to enjoy its complex and evolving flavors.
Understanding the different styles of sherry and how they age will help you appreciate this fascinating wine to its fullest. While sherry can go bad, with a little care, you can ensure that your bottle lasts as long as possible and continues to deliver a delightful experience, glass after glass.
