Can opened wine go bad in the fridge?

In this brief article, we are going to answer the question “Can opened wine go bad in the fridge?”

Can opened wine go bad in the fridge?

Yes, opened wine can go bad in the fridge. Excessive oxidation transforms wine into a salty drink. When a bottle of wine is opened, microorganisms begin to degrade the alcohol. It transforms the alcohol into acetic acid and acetaldehyde over time. 

These chemical components give wine its distinctive odor and harsh, acidic, and sour flavor. Additionally, alcohol may oxidize, reducing the wine’s freshness and flavor and imparting a taste comparable to bruised fruit.

Once a bottle of red or white wine has been opened, it is best to keep it in the refrigerator. Wines with a greater acidity content, such as sharp whites or dessert wines, retain their freshness for a bit longer.

Maintain a steady refrigerator temperature of around 15 degrees Fahrenheit. Additionally, store and preserve an opened bottle of wine in the same manner as you would an unopened one. Keep it away from direct sunlight, vibrations, and strong scents and store it sideways with the cork securely pressed into the bottle’s top.

Wine, like milk and fruit, deteriorates when exposed to air, which occurs after three days. For best results, open the bottle within a few days even if you have a wine stopper insert to help with this.

Once the cork is removed, oxidation occurs. Certain wines enhance initially when exposed to air but fade and lose their freshness after a day or two.

It does matter what sort of wine you are keeping since each variety requires a unique approach. While many wine experts advocate allowing red wine to breathe uncorked for an hour to enhance its characteristics, any longer than that necessitates re-corking and storing it in a cold (even chilly) dark spot.

After opening, white and rosé should be chilled. Sparkling wine should be consumed quickly after opening since it has a tendency to become flat. The same holds true with sparkling wine. 

What are techniques for wine storage?

There are several tools available for keeping open wine at good quality. However, if you have selected the appropriate wine preservation procedure. you should not need anything more than that. Additionally, the same considerations apply to the storage of open red wine.

Bear in mind that the more wine that remains in the bottle, the longer it will keep. Additionally, the more times the bottle is opened, the shorter the wine’s shelf life will be.

Stopper Bottles to Preserve the Freshness of Wine

To begin, cork wine in the manner in which a winemaker would. That is, reintroduce the end that was in the bottle. When corks are taken out, they expand, making it simpler to re-insert the end that was previously facing you into the bottle first.

It is a good idea to have an additional cork or three on hand, each somewhat variable in width, as wine bottlenecks are not uniform in size. 

This is also useful for those occasions when you intend to drink a bottle and discard the cork but then decide not to. Even wine bottle stoppers, made of glass, might be useful from time to time.

They often fit better in narrow-necked bottles. If everything else fails, use plastic wrap and a rubber band to secure the entrance.

Recork Open Wine Bottles

If you know you won’t finish a bottle, avoid leaving it uncapped on your counter or in your refrigerator. Replace the screw cap or insert the cork immediately after pouring your glass.

Likewise, if you are not going to complete a bottle of wine in one sitting, do not decant it. Allow the wine to breathe in the glass(es). Aerate a single serving by pouring it back and forth into a second wine glass.

To Preserve Open Wine Bottles, Refrigerate Them

Putting open wine in the fridge is a good thing, and there are almost no bad things about doing so. While cold temperatures dramatically slow oxidation processes, the open wine bottles in your refrigerator will continue to change.

Transfer Wine to a More Compact Container

Pouring half a bottle of wine into a 375 ml half bottle is a terrific technique to save money. 

Rather than exposing the other half of the bottle to oxygen across the whole circumference, you expose just a small section of the bottle’s neck to oxygen. Indeed, to prolong the life of the wine by several days, ensure that there is slightly more than half of the bottle remaining. 

Fill the 375 ml bottle almost to the brim. Yes, you will lose half an ounce or possibly an entire ounce, but the remainder of the wine will be much, much better preserved. It’s worth it!
