An opened bottle of red wine instantly changes as soon as you remove the cork. This is because oxygen affects flavour and aromas. On average, red wine remains good for 3-5 days after opening, provided you seal it tightly and keep it cool. Exactly how long depends on the type of wine:
Light red wine (such as Pinot Noir): 2-3 days
Full-bodied red wine (such as Cabernet Sauvignon): 4-5 days
Fortified wine (such as Port): 1-3 weeks
After opening, the oxidation process starts: first, oxygen helps the wine to "unfold" and aromas are released. Over time, too much oxygen breaks down the delicate flavours, so the wine becomes less fresh and can even start to taste sour. Therefore, always store opened wine in the fridge and seal the bottle tightly.
How do you taste if an opened red wine is still good?
Use your senses to judge its quality:
- Look at the colour: clear and lively usually means still good; brownish or cloudy wine indicates oxidation.
- Smell the wine: fruity, spicy aromas are a good sign; a smell of vinegar, wet cardboard or rotten fruit is a warning.
- Taste a small sip: fresh, fruity and balanced means drinkable; a sharp, sour or bitter taste indicates deterioration.
Is the wine no longer palatable? Don't worry, it is usually still safe to drink but is better used in cooking or discarded.
Tips for keeping red wine good for longer
- Store the bottle upright in the fridge
- Seal the bottle with a cork or wine stopper
- Use a vacuum pump to remove oxygen
- Pour into a smaller bottle to limit air contact
This is how to get the most out of your opened red wine, and make the most of each glass!
