Once you uncork your bottle of wine, you have up to two weeks (depending on the type of wine you’re drinking) before it goes sour. Can’t remember when you opened your bottle? Here’s how you can tell your wine has gone bad.
When a bottle of wine has been open for too long, it starts to grow bacteria from exposure to heat and oxygen. The result? A sour smell, similar to paint thinner, nail polish remover, or vinegar.
Oxidization can alter the original taste of the wine. If your wine has gone bad, it’ll either taste sour like vinegar or extremely sweet like caramelized applesauce.
You can usually tell a wine has gone bad simply by looking at the color and condition of it. Steer clear of wine that’s cloudy or brown — as browning is a result of oxygen exposure (like an apple!).
Do you see tiny bubbles in your wine? That’s because the air caused a second fermentation in the bottle, resulting in an oddly sour and fizzy texture.
