Does Wine Need to Be Refrigerated After Opening?
To preserve the freshness of the wine, it is best to store open wines in the refrigerator. Allow refrigerated red wines to warm to room temperature before serving.
Storing wine in the refrigerator helps slow chemical reactions and can keep it fresh for up to five days. Always store wine in an upright position to limit the surface area exposed to oxygen. Recorking the wine helps to seal it, but using a vacuum sealer can make it last even longer. Another option is to pour the wine into a smaller decanter and store it that way.
Storing wine in special wine refrigerators allows people to control the exact temperature of the wine. White wines should be kept at around 50 degrees, while red wines can be stored closer to 60 or 70 degrees.
