How Do You Know If Wine Has Gone Bad

Have you ever uncorked that bottle of wine you've been saving for a special occasion, only to wonder if it's past its prime? Fear not, fellow wine enthusiasts! The team at Black Wine Club is here with a comprehensive guide to help you determine if your beloved vino has taken a nosedive from delicious to disastrous. Join us as we take a deep dive into the world of wine spoilage and provide some expert tips on how to know if wine has gone bad.

What Causes Wine to Go Bad?

Before we jump into the signs of a spoiled wine, it's important to understand how and why wine goes bad in the first place. Typically, wine spoilage can be attributed to four main factors:

• Oxidation
• Heat Damage
• Light Damage
• Cork Taint

Oxidation

Oxidation is the most common cause of wine spoilage and occurs when the wine is exposed to too much oxygen. This can happen due to an improper seal on the bottle, or if the wine is left open for an extended period. Over time, oxygen exposure can cause the wine's flavors and aromas to fade, and may even result in vinegar-like flavors.

Heat Damage

Heat can wreak havoc on your precious bottle of wine. When wine is exposed to high temperatures, it can cause the wine to expand, pushing the cork out and allowing oxygen to enter. Not to mention, high temperatures can cause chemical reactions that affect the taste and quality of the wine.

Light Damage

UV light, particularly from direct sunlight, can be harmful to your wine as it can cause the wine's organic compounds to break down, altering its flavors and aromas. This is why it's crucial to store your wine in a dark, cool location.

Cork Taint

Lastly, cork taint occurs when a chemical compound called 2,4,6-trichloroanisole (TCA) contaminates the cork, which can then transfer to the wine. This results in a musty, damp odor and a very unpalatable taste.

Signs That Your Wine Has Gone Bad

Now that we know the main causes of wine spoilage, let's dive into the telltale signs that your wine may have gone bad.

1. Unpleasant Aroma: If your wine has an off-putting smell reminiscent of wet cardboard, damp basement, or vinegar, this could indicate cork taint or oxidation.
2. Changed Color: For red wines, look for a brownish hue, while white wines may become darker or more golden. A change in color could signal oxidation or light damage.
3. Flat or Lifeless Taste: If your wine seems to be lacking its usual complexity and depth, this may be a sign that it has been exposed to heat or oxygen.
4. Unusual Bubbles: If you notice bubbles in your non-sparkling wine, this can be a sign that it has undergone a secondary fermentation in the bottle, which could alter the taste.
