Fine wine is known to age, but that rule sadly does not apply once it has been opened. Once that seal had been broken, the contents of your bottle become exposed to the elements which the begins the process of oxidation.
Although oxidation does serve a purpose — we allow wine to breathe once opened, after all — too much can cause your wine to turn bad. Here’s what you should know.
How Should You Store Wine That Has Been Opened?
Once you’ve poured yourself a few glasses, or used the wine in a sauce or stew, you want to prevent the rest being exposed to air. Seal the bottle as tightly as you can, either with the cork or a wine stopper. You then want to keep the wine somewhere cool and dark like the fridge.
How Long Does Wine Last Once It’s Been Opened?
Oxidation behind the minute that air is introduced to the wine, so you have about 3-5 days to enjoy it before it becomes too affected. The time period depends on how much sulfur is in the wine, but sadly, anything sparkling will start to fizzle out after a day (pardon the pun).
When is it Time to Throw it Out?
Wine that has soured is no one’s idea of a good time. Any change in color, clarity, or smell should be taken as a red flag. While you can totally use that leftover booze to make vinegar, don’t drink it if it starts exhibiting any of those signs.
