How to preserve wine packed in cork?

Cork-packed wine is generally suitable for storage at a constant temperature of 12℃~ 15℃.

If the temperature changes too sharply, not only the wine body is easily damaged, but also the cork is easily affected by the temperature change, leading to wine seepage. It is best to put the wine packed with cork horizontally or obliquely, so that the wine liquid can contact the cork and ensure the cork is moist. If the wine is placed upright for a long time, the cork will dry and shrink because it does not contact with the wine, so the bottle mouth cannot be sealed. Air will enter from the gap, causing the wine to oxidize and deteriorate.
