After every pour into your glass , re-cork the wine. Keep the open wine bottle away from the light and at room temperature. In most situations, even red wines benefit from using a refrigerator to keep them fresher for longer.
Position the wine upright to reduce the surface area exposed to oxygen to get the best results. Yes, you certainly can refrigerate and freeze wine. When you place an open bottle in the fridge, you keep it at a controlled temperature and in a dark environment. The cooler temperature will also slow the oxidation. If you don't have access to a chiller or a wine refrigerator and you reside in a country with a hotter climate, you may store a corked yet unfinished bottle in the fridge.
Just remember to bring it out an hour before serving to allow it to come to room temperature. Wines can go bad in two ways once they've been opened. The first process involves acetic acid bacteria consuming the alcohol in wine and converting it to acetic acid and acetaldehyde.
The wine takes on a harsh, vinegar-like aroma as a result of this. The alcohol also might oxidize, resulting in a nutty, bruised fruit flavor that detracts from the wine's fresh and fruity qualities.
Because these are both chemical reactions, the lower the temperature a bottle of wine is kept, the slower they will occur. Pour a small amount into your glass and check for the following things:. Numerous wines are murky to start with, but if they are clear before and later turn cloudy, this could indicate microbial activity within the bottle.
It will start to brown and turn a different color. When exposed to oxygen, wine browns similarly to an apple. The browning of wine isn't always a bad thing; there are some fantastic "tawny" wines out there. It will, however, inform you how much oxidative stress the wine has experienced. The bubbles are the result of an unplanned second fermentation in the bottle.
Yes, in a way, you've just produced sparkling wine. Unfortunately, it won't be as enjoyable as Champagne; instead, it'll be strangely sour and spritzy. A wine bottle that has gone bad due to being left exposed has an abrasive and harsh aroma. It'll smell sour and medicinal, like nail polish remover, vinegar , or paint thinner. These smells result from chemical processes when the wine is exposed to heat and oxygen, causing bacteria to thrive and produce acetic acid and acetaldehyde.
To get it out of the way, drinking a wine that has "gone bad" won't hurt you, but it's probably not a good idea to consume it. A wine that has gone bad due to being left open has a harsh acidic flavor comparable to vinegar. It will likely burn your nasal passages in the same way horseradish does. Because of the oxidation, it also often has caramelized applesauce-like flavors. Unlike most foods sitting in your fridge for a week, older wines are safe to drink.
That bottle may have lost its flavor, taste, and brightness, but whether or not you appreciate it is entirely up to your palate. There is no such thing as expiration dates when it comes to wine. It isn't like a bottle of milk that should be discarded after the expiration date has passed. Wine ages slowly, and if stored correctly, it will continue to age.
If there's an opened bottle of wine in your fridge that looks questionable, you can run it through the three-step test we mentioned earlier.
Once a bottle of wine has been opened or uncorked, it's exposed to much more oxygen and therefore, the evolution process is drastically sped up. This is why you have a limited time to enjoy it at its peak of flavor.
However, although wine that's past its prime peak may taste a little flat or stale, it's not actually harmful to consume. As long as it tastes okay to you, feel free to drink it-just as in moments of desperation, a slightly brown avocado is better than no avocado.
Sparkling wines like Champagne, cava , and prosecco have the shortest enjoyment window-once the cork is popped, the bottle pressure that retains the bubbles dissipates and the wine turns flat. A sparkling wine stopper might help for a day or so, but I recommend you drink sparkling wine the day you open it. Sparkling wines are widely available in half bottles and even single-serve "minis" for this reason: to prevent "leftovers" for solo or duo drinkers who just want a single glass.
If you can't drink it, once sparkling wines can be wonderful for dressing up fresh fruit, like in this recipe for Plums with Sparkling Wine, Black Pepper, and Tarragon. If you want a white wine that will last, your best bet are wines from cool-climate growing regions because those wines naturally have higher acidity.

Some wine styles may last for up to five days after opening. Sparkling wines , such as Prosecco or Champagne, can stay fresh and will keep some fizz for a similar amount of time, but need to be properly sealed — ideally with a specific Champagne bottle stopper.

Perhaps you opened that bottle of Gamay a little late in the evening, or you only needed a splash of Pinot Grigio for your linguine and clams.
