How Long Before a Wine Cork Dries Out?

Properly stored wine corks can last decades. However, improper storage causes drying and crumbling in weeks.

Storage Best Practices

• Temperature: Cool, stable (10–15°C / 50–59°F).
• Humidity: 60–75% RH—keeps cork expanded, sealing the bottle.
• Orientation: Store bottles horizontally so wine contacts cork.
• Darkness: UV degrades cork and wine.
• Vibration-free: Prevents agitation.
• Not airtight containers: Some air exchange prevents mold; but avoid drafts.

For loose corks (unbottled): keep in sealed bag with damp cloth in fridge; use within months. Once a bottle is opened, re-cork tightly and refrigerate; consume within 1–3 days.
