Unopened Wine. Unopened wine should not be refrigerated in a standard kitchen refrigerator, which is too cold for long-term wine storage. Unopened wine should be stored on its side in a cool, dry place or in a special wine refrigerator. Opened White Wine. Opened white wine is best kept in the refrigerator. It should be recorked, preferably with a device that removes excess air from the bottle, and placed in the refrigerator. Though the flavor will start to deteriorate slightly after only one or two days, white wines usually remain drinkable for up to six days.
Do I need to refrigerate your red wine after opening it in order to keep it fresh? No. The wine will stay just as fresh at room temperature. With a bottled wine (red or white) you should refrigerate any left over wine after opening. Refrigerating an open bottle will slow down a chemical reaction called oxidation that spoils the wine. Oxidation occurs because the wine inside the bottle is exposed to air when itâs opened.
