How long does wine last after the bottle is open?
If you’ve asked this age-old question, you aren’t alone. Wine enthusiasts have long debated how long a bottle of wine lasts after opening. If you want to enjoy your wine with its intended flavor profile intact, we advise following these recommendations.
Lower-acid white wine can generally last 2-3 days, while high acidity will keep your wine fresh and vibrant for up to 5 days in the refrigerator.
Low-tannin reds (like pinot noir and merlot) will last 2-3 days. Higher-tannin reds should be very drinkable for up to 5 days after opening.
The primary concern once a bottle has been opened is exposure to oxygen, heat, and light. If the bottle is greater than half full, evacuated, and refrigerated, the wine should stay in a suitable condition for up to a week – as long as the bottle isn’t repeatedly opened and closed during this time.
