Most would agree that eventually, all wine will go bad. There are numerous ways that even an unopened bottle can go bad before you purchase it. Assuming nothing has happened to your unopened bottle, when does wine go bad? Is there anything you can do to prolong it’s life if you’re not going to finish an open bottle? 

In this buying guide, you will learn:

  • Why does wine go bad?
  • How does wine go bad?
  • Where does wine go bad? 
  • Options for storing an open bottle of wine
  • What wine savers are, and do they work?
  • Comprehensive product reviews for the best wine savers

Does Wine Go Bad?

The short answer is yes. How does wine go bad? The moment you uncork a bottle a powerful chemical process begins. Oxygen, wine’s mortal enemy, enters the bottle and the sulfur dioxide used as a preservative quickly escapes. In the short term oxygen enhances the flavor of your wine. That’s why correctly served wine is aerated (exposed to oxygen). Leave an open bottle unfinished for more than a couple of hours, however, and oxidation starts to occur. The countdown begins on your expensive bottle of wine. When does wine go bad? Where does wine go bad? Can the oxidation process be slowed down or stopped? Environment plays a big factor when answering these questions. 

Regardless of what method you choose for storing an open bottle of wine, experts generally agree that cooler temperatures help keep wine from deteriorating. At what temperature does wine go bad? Exact recommended temperatures depend on the type of wine, but a wine cooler or refrigerator is a must, even for reds. Colder temperatures help slow down the chemical processes, including oxidation. Whether you have a wine cooler or are just using the refrigerator, it is generally recommended you store your open wine bottle vertically. This leaves less surface area of the wine exposed to oxygen and slows down the oxidation process helping to keep your wine fresh. 

Wine Preservation Options

Now that you know an open bottle of wine should be stored vertically in the refrigerator for maximum life, what are the options for closing the bottle? Does wine go bad faster without an airtight seal? This is where the controversy begins. The old standard, and something some wine aficionados still swear by is merely replacing the cork. Enjoy a glass, replace the cork, pop the bottle into the fridge, and your wine will last for another day or two. If you’ve purchased a bottle with a screw cap, the process is even more straightforward. 

Wine savers have also become quite popular — most deal in some way with the oxygen problem. In basic terms, the wine saver pumps the air out of the empty portion of the bottle and then caps the bottle with an airtight seal. Sounds great in theory, right? But does wine go bad less quickly with these products? There is no correct answer. Amongst wine drinkers, you will find an equal number of people who swear by a particular wine saver, as you will those who stand by the cork method. 

The fantastic news is, you can try any number of wine saver devices for under $20! Run your own “does wine go bad” experiment and see what works for you without breaking the bank.

Making its debut over 30 years ago, Vacu Vin is still one of the most popular and widely known wine savers. mockins All in One Wine Accessory Set is another good choice in the vacuum seal category, and the ERHIRY Wine Bottle Stopper may be the choice for you if simplicity is your preference.

Vacu Vin Wine Saver Server

Vacu Vin touts its product as the first in the industry to help answer the question, how does wine go bad? According to the family-owned company, over 35 million households in 80 countries use their product. The newest version of the Vacu Vin still extracts the air from an open bottle of wine and seals it using a rubber stopper but also allows you to pour another glass without any drips. 

Vacu Vin comes with two rubber stoppers. Place one stopper in the neck of the open bottle, insert the pump, and the air is hand pumped out via a small hole in the stopper. The vacuum pump will “click” indicating enough air has been pumped out to leave a sufficiently oxygen-free environment. The air-tight sealed stopper remains inserted to keep your wine from going bad. Simply pull the tab on the stopper to break the air-tight seal when you’re ready to enjoy another glass and pour without removing the stopper for a drip-free serving. According to Vacu Vin, if properly hand-washed and taken care of, the rubber stoppers can be used over and over for years. Most Vacu Vin models come with two stoppers, but additional stoppers can be purchased separately if you commonly have more than two bottles of wine open at one time.
