Will Bad Wine Make You Sick? Understanding Spoiled Wine and Its Effects

Generally, drinking bad wine won’t make you violently ill in the traditional sense. While unpleasant flavors and aromas are the main consequence, consuming spoiled wine can, in some cases, lead to mild digestive upset or headaches due to the presence of certain bacteria or compounds.

What Makes Wine Go Bad?

Wine, a complex beverage resulting from fermentation, is susceptible to various forms of spoilage that can render it unpalatable and, in rare instances, potentially problematic. Understanding the factors contributing to its demise is crucial for appreciating its longevity and discerning the signs of degradation.

• Oxidation: One of the most common culprits. Excessive oxygen exposure transforms the wine, dulling its vibrant fruit flavors and aromas and imparting a Sherry-like or vinegary character. Proper storage, particularly tightly sealed bottles, helps mitigate this.
• Brettanomyces (Brett): A yeast species that can produce barnyard-like, horsey, or medicinal aromas. While some winemakers consider a touch of Brett complex and desirable, an overabundance is generally considered a flaw.
• Acetic Acid Bacteria (Acetobacter): These bacteria convert alcohol to acetic acid, resulting in vinegar. This is usually the result of poor hygiene or incomplete fermentation.
• Sulfite Reduction: In the absence of sufficient oxygen, sulfur compounds can be reduced, leading to unpleasant aromas reminiscent of rotten eggs or garlic.
• Cork Taint (TCA): Trichloroanisole (TCA) is a chemical compound often found in corks that imparts a musty, moldy, or wet cardboard aroma. It can render even the finest wine undrinkable.

Identifying Bad Wine: Tell-tale Signs

Distinguishing between a flawed wine and a perfectly aged one requires discerning observation and a developed palate. Here’s what to look for:

• Appearance: A cloudy or murky appearance, especially in wines that should be clear, can indicate spoilage. Excessive sediment is normal for older red wines, but significant cloudiness is a red flag for most other wines.
• Aroma: This is perhaps the most telling indicator. Look for aromas that are off-putting or inconsistent with the wine’s varietal characteristics. Vinegar, mold, wet cardboard, barnyard, or rotten egg smells are all signs of trouble.
• Taste: The flavor should mirror the aroma. If the wine tastes flat, sour, bitter, or otherwise unpleasant, it’s likely spoiled. A vinegary taste is a clear indication of acetic acid.
• Cork: A crumbly, moldy, or soaked cork could indicate potential issues with the wine. However, a perfect cork does not guarantee a perfect wine.

Health Concerns and Bad Wine

While catastrophic health outcomes are rare, drinking spoiled wine can, in specific circumstances, pose some health concerns:

• Sulfites: Some individuals are sensitive to sulfites, added as a preservative, and may experience allergic reactions. Spoilage doesn’t necessarily increase sulfite levels, but the degraded wine might amplify reactions due to other compounds present.
• Histamine: Found naturally in wine, histamine levels can increase during spoilage. People with histamine intolerance might experience headaches, skin flushing, or digestive issues.
• Bacteria: In rare cases, bacteria associated with spoilage could cause mild digestive upset, such as nausea, stomach cramps, or diarrhea. This is much less likely with commercially produced wines due to stringent quality control.
• Acetaldehyde: Produced as alcohol oxidizes, high levels can contribute to hangovers and headaches. Oxidized wine may contain elevated levels of acetaldehyde.

Storage is Key to Wine Longevity

Proper storage is paramount to preserving the quality and extending the life of your wine:

• Temperature: Store wine at a cool, consistent temperature, ideally between 55°F and 65°F (13°C and 18°C). Avoid significant temperature fluctuations.
• Humidity: Maintain moderate humidity (50-70%) to prevent corks from drying out and allowing oxygen to enter the bottle.
• Light: Protect wine from direct sunlight and artificial light, which can degrade its flavor and aroma.
• Position: Store bottles horizontally, ensuring the wine stays in contact with the cork to prevent it from drying out.

Types of Wine and Their Spoilage Tendencies

Different wines age and spoil in different ways. Here’s a brief overview:

Recovering Wine: What to do

Sometimes you can recover a wine that has only slightly deteriorated. Here are a few tactics:

• Decanting: For slightly oxidized wines, decanting can allow some off-flavors to dissipate.
• Hyperdecanting: Rapid aeration through a blender or wine aerator can sometimes revive a wine, though this is generally not recommended for delicate wines.
• Cooking: Spoiled wine can still be used for cooking, particularly in sauces, stews, and marinades. The heat will often eliminate undesirable flavors.

Frequently Asked Questions

Is it safe to drink wine that smells like vinegar?

While it likely won’t cause serious harm, wine that smells strongly of vinegar indicates the presence of acetic acid and is generally considered spoiled. The taste will be unpleasant, and it’s best to discard it.

Can bad wine give you food poisoning?

True “food poisoning” from bad wine is unlikely. However, some individuals might experience mild gastrointestinal distress due to certain bacteria or compounds present in spoiled wine. This is not the same as food poisoning caused by harmful pathogens like Salmonella or E. coli.

How long does wine last once opened?

Generally, red wine will last 3-5 days after opening, while white and rosé wines last 1-3 days. Sparkling wines lose their fizz quickly, typically within 1-3 days. Using a wine preserver can help extend the life of an opened bottle.

What does corked wine mean?

“Corked” wine refers to wine tainted by TCA (trichloroanisole), a chemical compound found in some corks. This imparts a musty, moldy, or wet cardboard aroma that masks the wine’s true flavors. It’s not harmful but renders the wine undrinkable.

Can old wine make you sick?

Very old wine, even if not technically spoiled, might have lost its flavor and complexity, but it’s unlikely to make you sick. However, if it shows clear signs of spoilage (vinegar, mold, etc.), it’s best to avoid it.

What is the white sediment at the bottom of my wine bottle?

This is most likely tartrate crystals, which are harmless byproducts of the winemaking process. They are more common in wines that have been stored at cool temperatures. They are not a sign of spoilage.

What happens if I drink wine that has been left open for a week?

Wine left open for a week will likely be oxidized and taste flat or vinegary. While it probably won’t make you sick, the flavor will be significantly diminished, and it’s unlikely to be enjoyable.

Can I use bad wine for cooking?

Yes, spoiled wine can often be used for cooking, especially in sauces, stews, and marinades. The heat will help evaporate any off-flavors and leave behind the underlying wine flavors. Avoid using extremely vinegary or moldy wine.

How can I prevent wine from going bad after opening it?

Use a wine preserver (vacuum pump or inert gas sprayer) to remove air from the bottle. Store opened wine in the refrigerator to slow down oxidation. Smaller bottles can also help reduce oxygen exposure.

Is it always obvious when wine has gone bad?

Not always. Subtle spoilage can be difficult to detect, especially for inexperienced palates. However, a combination of visual, olfactory, and taste cues can usually help identify spoiled wine.

Are there any wines that are naturally resistant to spoilage?

Wines with high acidity and tannins tend to be more resistant to spoilage due to their preservative properties. Wines aged under flor, like some Sherries, are also designed to withstand oxidation.

If my wine is slightly fizzy when it shouldn’t be, is it bad?

This could indicate refermentation in the bottle, often caused by residual sugar and unwanted yeast activity. While not necessarily harmful, it’s generally considered a flaw, and the wine may not taste as intended. It could also be light carbonation added on purpose, so context of the bottle and its style are important.
