How Long Does Wine Last Before It Goes Bad?
When it comes to Paul Marcus Wines, we get asked this question a lot: What is the best way for preserving an open but unfinished bottle of wine? “Pour some more!” as we like to say around here. Of course, this isn’t always an available choice.
You may conserve the leftover wine from an open bottle using a variety of ways and materials, but which option is the most effective depends on your needs and preferences.
The Reason Why Wine Goes Bad
First and foremost, we must understand what causes wine to rot in the first place before we can examine our alternatives for wine preservation. There are two key factors that contribute to the deterioration of wine.
There are two types of bacteria present: acetic acid bacteria and vinegar. The majority of the time, when you open a bottle of wine, there will already be trace levels of acetic acid bacteria in the bottle.
Growth is slowed as a result of the low oxygen levels and steady environment. The introduction of oxygen into a bottle of wine, on the other hand, will trigger chemical reactions among the acetic acid bacteria, ethanol, and sugar molecules that are already there.
This, in turn, results in the production of vinegar. When yeast (ethanol) ferments grape juice, it results in acetous fermentation, which occurs when acetic acid bacteria ferment grape juice with any remaining sugar in the wine (glucose).
Second, there’s oxygen and acetaldehyde to contend with. When wine comes into contact with oxygen, a chemical molecule known as acetaldehyde is generated as a byproduct.
On the plus side, acetaldehyde causes a concentration of color and aids in the development of complex scents and flavors–a touch of nuttiness, possibly notes of baked apples, and sometimes a grassy component.
(This is why decanting a wine helps to bring out the characteristics of the wine.) A wine that has been exposed to too much air, on the other hand, will no longer produce fresh fruit or have a powerful scent; instead, it will become flat-tasting, with little or no aroma and a dull, copperish tone.
How Long Does It Take for a Bottle of Wine to Go Bad?
Depending on the wine, the time it takes for it to rot might range from a single day to more than a month or more.
There is no one answer since it varies depending on the sort of wine you are drinking and how it is kept. We’ve compiled a list of the most common wine price ranges based on the most basic storage practices: cork in the bottle and bottle in the refrigerator.
Sparkling Wine should be consumed within 1-3 days after purchase.
Sparkling wines are supposed to last the least amount of time due to the carbonation that must be maintained in order for them to keep their glitter. The longer sparkling wine is kept in the bottle, the less brightness and effervescence will be seen on the subsequent pour.
Three to seven days for white wine and rose (light).
Because of the normally increased acidity and, in many cases, the use of stabilizing additives, lighter whites may be stored for an extended period of time in the refrigerator. Over time, you might anticipate the wines to develop oxidized characteristics and to lose their strength in flavor.
3 to 5 days for a full bottle of white wine
It may seem that a full-bodied white would not last as long as a lighter white, but this is due to the fact that they will oxidize at a much faster pace owing to the nature of the process by which they were manufactured.
Red wine should be consumed between 3-7 days.
Because of the presence of phenols in red wine, it may be kept for a somewhat longer period of time without losing its quality. Over the course of a week, red wines will begin to taste more vinegary and their vibrant fruit flavors will go away completely.
Some wines, on the other hand, need longer time to breathe (and hence more oxygen) in order to properly shine, and they typically taste better the following day. It’s quite OK to keep red wine in the refrigerator; just allow it to come back to room temperature (if desired) before serving.
1 to 8 weeks for fortified wine
Fortified wines, such as port and sherry, have a high concentration of alcohol and are, for the most part, heavily oxidized, allowing them to be kept for an extended period of time without deteriorating in quality.
That depends on your particular fortified wine and your specific preservation practices, to a certain extent.
A lighter, drier sherry like as fino or manzanilla, for example, would almost surely lose part of its zip within a few days, but a richer oloroso sherry will keep its zip for many weeks after being opened (or even months).
As it turns out, certain wines can be kept for months at a time. This is the location where Madeira and Marsala are welcomed.
As a consequence of heavy oxidation during manufacture and cooking of the grape must, these two fortified wines have rich taste profiles and aromas that are characteristic of oxidization.
While there are other fortified wines that can be kept for longer periods of time than a few weeks, these two will often keep for the longest time.

Do you know how to make a bottle last longer once it has been opened?
In order to preserve wine, it is necessary to maintain a regulated and oxygen-free atmosphere. Once a bottle of wine is opened, a buffet of chemical reactions begins to take place, many of which are potentially harmful, and there is no going back.
The only thing that can be done is to slow down these processes. Listed below are a few instruments and approaches for extending the shelf life of an open bottle of beverage.
Refrigerator
When it comes to storing wine after opening, the simplest method is to just place it in the refrigerator. Reduce the temperature of the wine in order to slow down the chemical processes that are going place in the glass.
This is true for all types of wine, including white, red, and fortified. It’s best to take red wines out of the refrigerator about an hour before they’re to be served if you want them to reach room temperature.
Wine Stopper with a Vacuum
Despite the fact that vacuum wine stoppers have become the latest craze in wine preservation, we do not suggest using them. While they purport to eliminate oxygen from the bottle, this produces a double-edged sword in terms of safety and effectiveness.
The vacuum will generate a negative pressure, which will draw diluted gases out of the wine as well as the container in which it is being stored.
As a result, some individuals feel that the vacuum effect within the bottle also decreases aromatics in the wine and that the wine may be harmed rather than protected as a result.
Preserve on Private Property
Spraying in a combination of three atmospheric gases (carbon dioxide, nitrogen, and argon) is a straightforward and most efficient approach for controlling pests and diseases.
Creating a low-oxygen environment within the bottle by replacing the oxygen present with these inert gases, which do not have the same negative consequences as oxygen, can inhibit bacterial growth and slow the fermentation process down significantly.
This spray may also be used to preserve other perishable items such as fruits and vegetables, so having a supply on hand is a good thing to have.
Bottle half-full
Using a smaller bottle to keep open wine, we feel, is the most effective means of preserving open wine. If you are unable to complete a bottle of wine, have a clean 375ml bottle on hand for emergencies.
Pour the remainder of the contents into this bottle and store it in the refrigerator for longer storage durations. While the wine has already come into contact with oxygen, the amount of headspace left in the bottle is significantly decreased, allowing the negative processes to be slowed and the shelf life of your product to be extended.
