The act of resealing an opened bottle of wine with its original closure aims to preserve the liquid’s quality after initial uncorking. This process involves carefully reinserting the cylindrical stopper back into the bottle’s neck. For example, after consuming a portion of a wine bottle, one might attempt to prevent oxidation by placing the cork back in its opening.
Effectively sealing wine after opening extends its drinkability window, slowing down the rate at which it spoils. This helps avoid wastage and allows for the enjoyment of a single bottle over multiple occasions. Throughout history, different methods have been used to preserve open wine, but using a cork remains a common and practical solution when other preservation tools are not available.
