Corks, natural, agglomorated, synthetic

Winegrowers Supplies - Corks and stoppers

After corking with natural corks, the bottles should stand upright for at least 3 hours before they are laid down horizontally in stillages.
This is to allow the cork to expand again (to about 95% of it's size) and form a good seal against the bottle neck.
If laid horizontally too soon, wine can seep between the cork and bottle neck, leading to leakage.

For wine bottles with an internal diameter of 18.5 mm (DIN EN 12726 states 18.3 mm +/- 0.2 mm) a 24 mm diameter cork is recommended.
