What are the benefits of storing wine flat?

For wines sealed with corks, the benefits of storing them flat are:

(1) Laying the wine bottle flat allows the wine liquid to contact the cork, which is beneficial to keeping the cork moist and elastic, and the cork is not easy to break when opening the bottle.

(2) Placing the wine bottle flat can also keep the cork moist and well sealed. In this way, the tiny pores of the cork allow trace amounts of oxygen to penetrate, allowing the wine to "breathe" slowly, developing aged aromas such as animal fur, earth, leather, and mushrooms, and increasing the complexity of the wine's aroma. If the humidity of the cork becomes poor, the pores in the cork and the gap between the cork and the wine bottle will undoubtedly become larger. When a large amount of oxygen penetrates, the wine will easily deteriorate.

(3) The wine bottle is placed flat and the wine liquid is in complete contact with the cork, which can give the wine some tannin and aroma. Because cork is made of oak bark, it can be considered to have similar functions to oak barrels. Of course, this function of cork is very small.
