How Long Will That Open Bottle of Wine Actually Last? We Asked an Expert

The article titled "How Long Will That Open Bottle of Wine Actually Last? We Asked an Expert" from CNET delves into the intricacies of wine preservation after opening. The piece is structured around an interview with a wine expert, providing detailed insights into the factors affecting the shelf life of an opened bottle of wine, and offering practical advice on how to extend its drinkability.

The article begins by addressing a common concern among wine enthusiasts and casual drinkers alike: how long can an opened bottle of wine last before it goes bad? The expert, identified as a sommelier, explains that the answer isn't straightforward as it depends on several variables, including the type of wine, storage conditions, and the method used to preserve it after opening.

The first section of the article discusses the different types of wine and their varying lifespans once opened. Red wines, according to the expert, tend to last longer than white wines due to their higher tannin content, which acts as a natural preservative. A typical red wine can last up to five days if stored properly, whereas a white wine might only last three to five days. Sparkling wines and rosés fall somewhere in between, with an average lifespan of three to four days. The expert emphasizes that these are general guidelines and that individual wines can vary significantly.

The article then shifts focus to the importance of storage conditions. Temperature, light, and air exposure are highlighted as critical factors that can either extend or shorten the life of an opened bottle of wine. The ideal storage temperature for wine is between 45 and 65 degrees Fahrenheit, with the expert recommending a cooler end of the spectrum for opened bottles to slow down oxidation. Light, particularly UV light, can degrade wine, so storing it in a dark place is advised. The most significant factor, however, is air exposure. Once a bottle is opened, the wine begins to oxidize, which can lead to a change in flavor and aroma. The expert suggests recorking the bottle tightly or using a wine stopper to minimize air contact.

The next section of the article explores various methods to preserve an opened bottle of wine. The simplest and most accessible method is recorking the bottle and storing it upright in the refrigerator. This method can extend the life of the wine by a day or two. For those looking for more advanced solutions, the article discusses wine preservation systems. These systems typically involve replacing the air in the bottle with an inert gas, such as argon, which slows down oxidation. The expert notes that while these systems can be effective, they are more suited for frequent wine drinkers due to their cost.

The article also touches on the use of vacuum pumps, which remove air from the bottle to create a vacuum seal. While these devices are less expensive than gas preservation systems, the expert cautions that they can sometimes alter the taste of the wine if not used correctly. Another method mentioned is transferring the wine to a smaller container to minimize air exposure. This technique is particularly useful for sparkling wines, as it helps maintain their effervescence.

In addition to discussing preservation methods, the article provides guidance on how to tell if an opened bottle of wine has gone bad. The expert explains that the primary indicators are a change in color, the development of off odors, and a noticeable shift in taste. Red wines might turn brown, while white wines could take on a darker hue. The smell of vinegar or nail polish remover is a clear sign that the wine has oxidized beyond the point of enjoyment. The taste might become flat or overly acidic, indicating that the wine is no longer at its best.

The article concludes with some practical tips for wine lovers. The expert advises against saving small amounts of wine, as they tend to spoil quickly. Instead, it's better to finish the bottle or share it with friends. For those who frequently have leftover wine, investing in a preservation system might be worthwhile. The expert also encourages readers to experiment with different preservation methods to find what works best for their needs and preferences.

Overall, the article provides a comprehensive overview of the factors affecting the shelf life of an opened bottle of wine and offers actionable advice for extending its drinkability. By understanding the type of wine, optimizing storage conditions, and employing the right preservation techniques, wine enthusiasts can enjoy their favorite bottles for longer periods. The expert's insights serve as a valuable resource for anyone looking to make the most out of their wine collection.
