How to preserve a bottle of red wine once opened

Opening a bottle of red wine is always a special moment, since it serves both to accompany a dinner as a couple, a meal with friends or simply to enjoy a drink at the end of the day. However, there is a question that many of us ask ourselves right after uncorking it: “what do I do with the leftover wine?” Unlike other drinks, we must understand that wine is a much more living product, which evolves from the moment it comes into contact with oxygen. This is the same transformation that allows all its aromas to unfold when opening the bottle of wine. However, by uncorking it and letting the drink come into contact with oxygen, can, in a short time, end up ruining its original flavor and character. Therefore, preserving a bottle of red wine once opened is essential, although this can be quite a complex task if we want to enjoy these types of drinks for longer if we are not going to drink the entire bottle during the first hours after opening. You don't need to be a professional winemaker to do it correctly, since it is enough to know what techniques work and what actions should be avoided. For this reason, in this article we are going to show you the best ways to extend the life of your opened wine so that each glass is enjoyed like the first. Keep reading if you want to meet them with us!

Recap the bottle

One of the most common mistakes we usually make when wondering how to preserve opened red wine is leaving the bottle uncovered for hours or days and trying to drink it later. Oxygen, although necessary for wine to breathe, is its worst enemy in the long term, since accelerates oxidation and degrades both color, aroma and flavor. The simplest and most effective way to preserve opened wine is to immediately recap the bottle. The ideal is that we use the original cork itself, making sure to insert it through the part that was originally in contact with the wine. However, if the cork is broken or we simply want to take conservation to the next level, there are more effective solutions, such as tspecial silicone plugs, manual or electric vacuum preservers and even more sophisticated systems that allow oxygen to be extracted from the bottle before storing it. The more hermetic the closure is, the more days we can enjoy the wine in optimal conditions.

Put the bottle in the refrigerator

Although it may surprise those people who are not familiar with conservation techniques, one of the keys to how to preserve an open bottle of red wine is to put it directly in the refrigerator. It must be taken into account that the cold slows down the chemical reactions caused by oxygen and, consequently, allows the durability of the wine to be prolonged.Of course, it is worth keeping in mind that red wine is not served as cold as white or rosé. The recommended serving temperature is usually between 12 and 16 ºC, depending on whether we are talking about a young, aged or reserve wine. Therefore, the ideal is to remove the bottle from the refrigerator a few minutes before serving so that it recovers its proper temperature.

Store the bottle upright

Before opening a bottle of wine, we all know that it is advisable to store it horizontally. This keeps the cork in contact with the liquid and prevents it from drying out. However, when we have already uncorked the cork and are considering how to preserve an open bottle of wine, the rule changes. In this case, it is best to keep the bottle in a vertical position. In this way, we can reduce the surface of the wine that remains in contact with the air, which slows down the oxidation process. Although wine, once opened, cannot be stored for months, this simple measure can help keep it in more than acceptable conditions for a few more days.

Do not expose it to the sun or light sources

Another of the great threats to wine, in addition to oxygen, is light. Exposing an open bottle to sunlight or intense artificial sources can accelerate its degradation process. The riboflavin present in wine is especially sensitive, since, in contact with light, can trigger chemical reactions that cause unpleasant odors —such as notes of onion or garlic—and a dull or bland taste. For this reason, we can say that, in addition to covering the bottle and storing it cold, it is advisable to avoid any source of direct light. The refrigerator is an ideal place not only because it allows you to control the temperature, but also because keeps the bottle upright and in a dark and stable environment. The key is to minimize the factors that usually alter the integrity of an opened wine. If you have ever wondered how to preserve opened red wine without losing quality, keep this tip in mind: the less you expose the bottle to light and heat, the more likely it will retain its properties for longer than usual.

Approximately how long does an open wine last according to its type?

A fairly common question is usually “how long does an opened wine really last?” The truth is that there is no single answer, since depends on the type of wine and how we have preserved it. However, we can give general references that help you orient yourself. For example, when we talk about white and rosé wines, it is usual for them to remain in good condition for two to three days.Now, when we talk about young red wines, we can say that, thanks to their concentration of tannins, they usually last up to a week if kept cold and well covered. For their part, crianza, reserva or gran reserva red wines, due to their aromatic complexity, tend to be more sensitive. For this reason, the ideal is to consume them within a maximum period of three or four days. Of course, the time is approximate and always depends on how each of the previous measures that we have mentioned is applied, such as the use of airtight lids, storage in refrigerated and dark conditions and in a vertical position.

Knowing the characteristics of the wine is essential

Beyond the techniques, understanding how to preserve an open bottle of red wine is also understanding the nature of this drink. Wine is the fruit of the land, the work in the vineyard and a production process that seeks to maintain the highest quality in each bottle. Respecting it after opening it is, in some way, honoring all the effort made by professionals in the sector. Therefore, when buying and enjoying a good wine, it is important to always keep in mind the importance of its conservation. In our red wine catalog you can find a wide range of options, from fresh young to elegant reserves, and each of them requires different care once opened. In short, if you are wondering how to preserve opened red wine, it is possible to do so by carrying out a few small actions that can make a difference. It is not only about prolonging the life of a bottle for a few more days, but also about ensuring that each glass we serve retains the character, aromas and quality that the winemaker wanted to convey to us when bottling it.
