Why is wine stored horizontal?

Here's why:

* Cork's role: The cork is the primary barrier between the wine and the outside world, preventing oxygen from entering and the wine from oxidizing (spoiling).

* Cork's vulnerability: Cork is a natural material, and it can dry out and become brittle if exposed to air for extended periods.

* The problem with vertical storage: When a bottle is stored vertically, the cork is constantly in contact with the air inside the bottle. This can cause the cork to dry out, shrink, and allow oxygen to penetrate the wine.

* Horizontal storage solution: Storing the bottle horizontally keeps the cork submerged in the wine. This constant contact with the wine keeps the cork moist and prevents it from drying out.

In short, horizontal storage helps maintain the integrity of the cork, ensuring that the wine stays fresh and protected from oxidation.
