How do you prevent cork bottles from popping or corks lifting during shipping to warm climates?

Cork bottles are prone to cork lift and popping in heat due to the vacuum inside the bottle and liquid expansion. Members who experienced this (particularly when shipping to warm regions like Taiwan and the Philippines) shared several practical solutions:

- **Shrink caps** — upgrade from paper tamper labels to full plastic shrink caps to seal the cork entirely. Paper seals alone are insufficient; one member reported a cork popping off a sample bottle in the Philippines despite using paper seals. - **Horizontal storage** — store bottles on their sides during shipping so the cork stays damp and has greater friction against the bottle neck. This is an old-school approach (Schweppes historically used skittle-shaped bottles to force horizontal storage). - **Temperature-controlled shipping** — use refrigerated or temperature-controlled container services, though members noted this increases shipping costs significantly.

**Caveats:** Even with precautions, heat-related cork lift can damage retail presentation (one member's products arrived on Taiwan shelves with visibly lifted corks, though they didn't fully pop). If you ship to consistently hot climates without these measures, expect potential losses. Insurance may not cover bottle damage from pressure-related issues, so clarify your policy in advance.
