Yes, a dried-out cork can cause wine leakage. This is because the cork becomes brittle and no longer forms a proper seal, allowing air to enter the wine bottle and causing it to spoil.

Store wine bottles in a horizontal position. This allows the wine to stay in contact with the cork, keeping it moist and preventing air from seeping into the bottle.

Humidity occurs when moisture builds up inside shipping containers due to temperature differences between the inside and the outside environment. Excess humidity can cause corks to expand or contract, leading to wine leakage.
