How To Know If Wine Is Bad

So, you've popped open a bottle of wine to enjoy with friends, but something just doesn't seem right. The smell, the taste, or maybe even the color appears off, and you can't help but wonder: has the wine gone bad? Fear not, fellow wine lovers! In this blog post, we'll explore the telltale signs that your wine has turned, and what to do if you find yourself in such a situation. Join us at Black Wine Club as we take a closer look at the ultimate question: how to know if a wine is bad?

Signs That Your Wine May Be Spoiled

Wine can go bad for a variety of reasons and sometimes, it can be challenging to detect the issues. Here are some common signs that may indicate your wine has spoiled:

Smell

• Vinegar Aroma: One of the most telling signs that a wine has gone bad is when it smells like vinegar. This can occur when the wine has been overexposed to air, causing it to oxidize and develop a sour, unpleasant scent.
• Musty, Moldy Aroma: A damp, moldy, or musty smell can indicate that the wine has been contaminated by a cork tainted with TCA (2,4,6-trichloroanisole), a natural compound that is responsible for "cork taint," ruining the wine's smell and taste.

Taste

• Sour or Flat Taste: If your wine tastes sour, flat, or unappetizing, it may have undergone a second fermentation after bottling, which often means the wine is spoiled.
• Bitter or Metallic Flavor: An off-putting or metallic taste can signify a wine that has gone bad. This could be due to oxidation, a chemical reaction between the wine's natural compounds and oxygen.

Appearance

• Brown or Murky Discoloration: If your wine has a brown or muddy discoloration, it is likely spoiled. Oxidation or prolonged exposure to light can cause these undesired color changes.
• Bubbles in Non-Sparkling Wine: When unexpected bubbles are present in a still wine, it could mean that it has undergone a secondary fermentation, which is an unwanted process leading to spoilage.

How to Prevent Wine Spoilage

While some wine spoilage is unavoidable, proper storage and handling can help you preserve the quality and taste of your wine. Here are a few tips to keep your wine in top condition:

Proper Storage

• Store unopened wine bottles in a cool, dark, and slightly humid environment. Coolers or wine cellars maintain optimal conditions: temperatures around 55°F (12°C) and a humidity level of 60-70%.
• Keep wine bottles on their sides to keep the cork moist and prevent it from drying out, which could lead to oxidation.

Handling Opened Bottles

• Use a wine preserver to remove oxygen from the bottle and reseal it with a vacuum seal or specialized wine stopper.
• Store opened wine in the refrigerator to slow down oxidation.
