We’ve all been there: reaching for a leftover bottle of wine, only to question its freshness. But fear not, fellow wine enthusiasts! Here are three simple ways to identify whether your opened wine has gone bad:

1. Inspect the Look:

  • Color: Red wines losing their vibrancy, turning brownish or dull, might be past their prime. White wines can develop a brownish hue or cloudiness, indicating spoilage. However, remember that color changes can also occur during natural aging, so this alone isn’t a definitive sign.

2. Unleash the Aroma:

  • Smell: Wine that has gone bad often develops unpleasant aromas. Look out for vinegar-like scents, which indicate oxidation. Musty, moldy, or wet-cardboard smells can also be signs of spoilage or “cork taint,” caused by a faulty cork. Conversely, a lack of the original fruity or floral aromas might simply indicate the wine has lost its freshness due to prolonged exposure to air.

3. Take a Sip Test (with Caution):

  • Taste: If visual and olfactory clues aren’t conclusive, a cautious sip can be the final verdict. Spoiled wine can have a sharp, vinegary taste, or an overly sweet, dull flavor. However, if you’re unsure, it’s always best to err on the side of caution and discard the wine to avoid any potential stomach upset.


Trust your senses! If something seems “off” about your wine, it’s likely best to avoid consuming it. When in doubt, throw it out!

Bonus Tip:

Store opened bottles of wine upright in the refrigerator with a cork or wine stopper to minimize air exposure and slow down the spoilage process. This can help extend the lifespan of your opened wine for a few days, allowing you to enjoy the rest without worry.

So next time you reach for that leftover bottle, these simple tips will help you determine if it’s still good to go, ensuring a happy (and safe) wine experience.
