Wine, a beverage enjoyed for centuries, is known for its complexity and aging potential. However, once a bottle is opened, the clock starts ticking. The question of whether you can safely and enjoyably drink wine that’s been open for six days is a common one, with no simple yes or no answer. Several factors come into play, influencing the wine’s quality and your drinking experience.
Understanding Wine Degradation After Opening
The moment a bottle of wine is uncorked, it’s exposed to oxygen. This initiates a process called oxidation, which, while beneficial in controlled winemaking environments, can lead to the wine’s eventual spoilage once opened.
The Role of Oxidation
Oxygen interacts with the wine’s compounds, altering its aroma, flavor, and color. Initially, a little oxygen can actually “open up” the wine, releasing its aromas and making it more expressive. This is why decanting is often recommended. However, prolonged exposure leads to a flattening of flavors, a dulling of aromas, and eventually, a vinegary taste.
Other Contributing Factors
Besides oxidation, other factors contribute to wine degradation. These include:
-
Microbial Activity: Bacteria and yeast, present in the air, can feed on the alcohol and sugars in wine, producing acetic acid (vinegar) and other undesirable compounds.
-
Temperature: Warm temperatures accelerate oxidation and microbial growth.
-
Light Exposure: Sunlight and artificial light can also degrade wine, especially white wines.
Factors Influencing a Wine’s Longevity After Opening
The type of wine, how it’s stored, and how much is left in the bottle all impact how long it will remain palatable after opening.
Wine Type Matters
Different wine types have varying levels of tannins, acidity, alcohol, and sugar, which act as preservatives and influence their lifespan after opening.
-
Red Wines: Red wines, especially those high in tannins like Cabernet Sauvignon or Syrah, generally last longer than white or rosé wines. Tannins act as antioxidants, slowing down the oxidation process. A robust red might still be enjoyable after five to seven days, especially if properly stored.
-
White and Rosé Wines: These wines are more delicate and susceptible to oxidation. Lighter-bodied whites and rosés typically last three to five days in the refrigerator. Higher-acidity whites like Sauvignon Blanc might last a bit longer.
-
Sparkling Wines: Sparkling wines, like Champagne or Prosecco, lose their bubbles quickly after opening. They’re best consumed within one to three days, even with a sparkling wine stopper.
-
Fortified Wines: Fortified wines, such as Port or Sherry, have a higher alcohol content, which acts as a preservative. They can last for several weeks, even months, after opening if properly stored.
Storage Conditions are Crucial
Proper storage significantly extends a wine’s lifespan after opening.
-
Refrigeration: Refrigerating opened wine slows down the oxidation process and inhibits microbial growth. Even red wines benefit from refrigeration after opening. Take red wine out of the refrigerator an hour or two before serving to allow it to warm up slightly and express its aromas.
-
Re-corking: Immediately re-cork the bottle after pouring. This minimizes the surface area exposed to oxygen. Use the original cork, or a tight-fitting alternative.
-
Vacuum Sealing: Vacuum sealing devices remove air from the bottle, further slowing down oxidation. These devices can be effective, but they don’t remove all the oxygen and aren’t a perfect solution.
The Importance of the Remaining Volume
The less wine left in the bottle, the more air is present, and the faster the wine will oxidize. A half-empty bottle will degrade much quicker than a bottle that’s mostly full.
Assessing a 6-Day-Old Wine: What to Look For
Before pouring yourself a glass of 6-day-old wine, take a moment to assess its condition.
Visual Inspection
-
Color: Check for significant changes in color. Red wines may develop a brownish hue, while white wines may darken.
-
Clarity: Look for any cloudiness or sediment that wasn’t present when the bottle was first opened. While some sediment is normal in older red wines, a sudden appearance of cloudiness in a previously clear wine could indicate spoilage.
Aroma Check
-
Off-Odors: Sniff the wine carefully. Look for any unpleasant or unusual smells, such as vinegar, wet cardboard, or a musty odor. These are telltale signs of oxidation or microbial spoilage.
-
Faded Aromas: If the wine smells muted or lacks its characteristic aromas, it may have lost its freshness and complexity.
Taste Test
-
Sour or Vinegary Taste: A sour or vinegary taste is a clear indication that the wine has oxidized and turned to acetic acid.
-
Flat Flavors: If the wine tastes dull, lifeless, or lacks its original flavor profile, it’s likely past its prime.
-
Unpleasant Aftertaste: An unpleasant or lingering aftertaste can also be a sign of spoilage.
Potential Risks of Drinking Old Wine
While drinking wine that has been open for too long is generally not harmful, it may not be a pleasant experience.
Safety Considerations
Wine spoilage primarily affects taste and aroma, not safety. The alcohol content in wine inhibits the growth of most harmful bacteria. However, in rare cases, improper storage or contamination could lead to the growth of undesirable microorganisms.
The Impact on Taste and Enjoyment
The primary concern with drinking old wine is the diminished flavor and aroma. The wine may taste flat, sour, or simply unpleasant, ruining the drinking experience. It is better to err on the side of caution and discard the wine if you are unsure of its quality.
Tips for Preserving Opened Wine
Here are some tips to maximize the lifespan of your opened wine:
-
Re-cork Immediately: Always re-cork the bottle tightly after pouring a glass.
-
Refrigerate: Store opened wine in the refrigerator, regardless of whether it’s red, white, or rosé.
-
Use a Wine Preserver: Consider using a vacuum sealing device or inert gas spray to remove air from the bottle.
-
Transfer to a Smaller Bottle: If you have only a small amount of wine left, transfer it to a smaller bottle to minimize air exposure.
Creative Uses for Leftover Wine
If you have wine that is no longer enjoyable to drink, don’t throw it away! There are many creative ways to use leftover wine in cooking.
-
Cooking: Use red wine to make sauces, stews, or marinades. White wine can be used in risotto, seafood dishes, or as a deglazing liquid for pans.
-
Wine Vinegar: Turn leftover wine into homemade wine vinegar.
-
Wine Ice Cubes: Freeze leftover wine in ice cube trays for use in sangria or other cocktails.
Conclusion: To Drink or Not to Drink?
Ultimately, the decision of whether to drink 6-day-old wine depends on several factors, including the type of wine, how it was stored, and your personal preferences. By understanding the factors that contribute to wine degradation and assessing the wine’s condition, you can make an informed decision. If the wine looks, smells, and tastes good, then enjoy it! But if you have any doubts, it’s best to err on the side of caution and discard it. After all, life is too short to drink bad wine.
The Bottom Line: Key Takeaways

If in doubt, throw it out. It’s better to discard wine that has gone bad than to risk an unpleasant drinking experience.
Can I drink wine that’s been opened for six days?
Generally, yes, you can drink wine that has been opened for six days, but its quality will likely have deteriorated. The exposure to oxygen causes wine to oxidize, leading to changes in flavor and aroma. The extent of the decline depends on several factors, including the type of wine, how it was stored, and how much wine remained in the bottle.
Red wines, especially those with higher tannin levels, tend to hold up better than white or rosé wines. Proper storage, such as in a cool, dark place with the bottle recorked, can significantly slow down the oxidation process. However, even under optimal conditions, a noticeable loss of freshness and vibrancy is expected after six days. Taste the wine first; if it’s unpleasant or vinegary, it’s best discarded.
What are the signs that opened wine has gone bad?
Several signs can indicate that opened wine has deteriorated too much to enjoy. The most obvious is a change in smell; the wine may develop a vinegary, sour, or even moldy odor. Look for a loss of fruitiness; the vibrant aromas should be replaced by dull or off-putting scents. The color might also change, with red wines taking on a brownish hue.
Beyond smell and appearance, the taste is the ultimate indicator. A spoiled wine will often taste flat, acidic, or distinctly unpleasant. It might lack its original flavor profile, tasting noticeably different from when it was first opened. If you experience any of these signs, particularly an unpleasant smell or taste, it’s best to discard the wine rather than risk an unpleasant experience.
How does wine type affect its longevity after opening?
The type of wine significantly impacts how long it remains palatable after being opened. Red wines, especially full-bodied ones like Cabernet Sauvignon or Merlot, typically last longer due to their higher tannin and acidity levels, which act as natural preservatives. These compounds help to slow down the oxidation process, allowing the wine to retain its character for a few days longer.
White and rosé wines are generally more delicate and susceptible to oxidation. Lighter-bodied whites, like Sauvignon Blanc or Pinot Grigio, and rosé wines often lose their freshness and vibrancy much quicker than reds. Sparkling wines, such as Champagne or Prosecco, present a unique challenge as they also lose their effervescence rapidly after opening, typically becoming flat within a day or two.
What’s the best way to store opened wine to prolong its life?
Proper storage is crucial for extending the life of opened wine. The two most important factors are temperature and oxygen exposure. Store the bottle in a cool, dark place, ideally in a refrigerator, to slow down the chemical reactions that lead to oxidation. Remember to remove the bottle about 30 minutes before serving to allow it to warm up slightly and release its aromas.
Minimizing oxygen exposure is also vital. Recork the bottle tightly using the original cork or a wine stopper. Vacuum wine preservers, which remove air from the bottle, can further extend the wine’s lifespan. Consider using inert gas sprays, such as argon, to create a protective layer over the wine’s surface, preventing oxygen from coming into contact with the liquid. These methods, combined with proper temperature control, will significantly help preserve the wine’s quality.
Does a half-empty bottle of wine go bad faster?
Yes, a half-empty bottle of wine will generally go bad faster than a nearly full bottle. This is because the greater the amount of air (oxygen) in the bottle relative to the amount of wine, the quicker oxidation occurs. Oxidation is the primary culprit in the degradation of opened wine, leading to changes in flavor, aroma, and overall quality.
With more air in the bottle, a larger surface area of the wine is exposed to oxygen, accelerating the breakdown of compounds that contribute to the wine’s desired characteristics. This increased exposure can lead to the development of undesirable flavors, such as a vinegary or stale taste. Therefore, it’s best to consume wines from partially full bottles sooner rather than later to minimize the impact of oxidation.
Can you use 6-day-old wine for cooking?
Using 6-day-old wine for cooking is generally acceptable, especially if the wine hasn’t turned noticeably sour or vinegary. The cooking process can often mask some of the minor off-flavors that might have developed due to oxidation. However, it’s crucial to assess the wine’s quality before using it in your dish. If the wine smells or tastes significantly deteriorated, it’s best to avoid using it.
When using older wine for cooking, opt for dishes with bold flavors that can complement or balance any subtle off-notes. Stews, braises, and sauces are often good choices. Avoid using it in delicate preparations where the wine’s flavor is a central component, as the diminished quality might negatively impact the final result. Remember that the quality of the wine used in cooking still matters; the better the wine, the better the dish will taste.
Are there any health risks associated with drinking old, opened wine?
Generally, there are no significant health risks associated with drinking old, opened wine, provided it hasn’t visibly spoiled (e.g., mold growth). The wine might taste unpleasant due to oxidation and the formation of acetic acid (vinegar), but these changes are typically not harmful. The alcohol content also helps to inhibit the growth of most harmful bacteria.
However, it’s always prudent to exercise caution. If the wine exhibits signs of significant spoilage, such as cloudiness, sediment formation (beyond natural tartrates), or a foul odor suggesting bacterial contamination (like mercaptans – sulfurous smells), it’s best to discard it. While the risks are low, consuming wine that has clearly gone bad might lead to mild digestive upset in some individuals.
