You could simply place the wine in the refrigerator, but it will come out at the wrong temperature. There is an optimal temperature at which wine is served, and the temperature is dependent on the type of wine. Here, the knowledgeable wine cellar staff can be invaluable. Another option is to place the bottle of wine in a cooling sleeve, but the sleeve, or in some cases inserts for the sleeve, must be placed in the freezer. Again, you have no real control of the temperature, and once the sleeve warms you have to take out another or serve warm wine. Inserting a cooling rod directly into the bottle is problematic since it requires that you make room for the rod by pouring about a glass of warm wine out first. And, since the rods are normally chilled in a freezer you lose control of the temperature.
The option of purchasing a multiple bottle of wine chiller is an expensive option, and uses a lot of space. It is like adding a second refrigerator, perhaps a small one, to your home. Most people do not have that much extra space.
Perhaps the best option is an electric, single bottle wine chiller. There is a temperature control, and you can tell when the wine is chilled using an LED display of the temperature.
