Now that you have selected your wine, it is important to store the bottle correctly and to serve the beverage at the correct temperature, according to its type.
Before you are ready to serve the wine, store the bottle on its side so the cork stays moist. If the cork dries out, it will not be effective as it will allow air into the bottle.
White wine is best stored lightly chilled at around 45 degrees. A red is best at room temperature or slightly chilled to about 60-65 degrees. It is better to serve wine too cool as opposed to too warm. When wine is too warm, the alcohol flavor is brought to the surface and is not as enjoyable to drink.
Unfinished bottles of wine will keep for up to about a week in the refridgerator. Jam the cork back into the bottle or purchase a stopper in order to keep air out of the bottle. There also are products available that extract air from the bottle before corking them which may allow the wine to last a little longer. It is best, however, if you can finish the wine within the next few days.
