An average small wine cooler will store 12 bottles however much larger models are available as well as much smaller models all the way down to single bottles.
A wine cooler is specifically designed to store wine from a temperature and humidity standpoint. The temperature of a wine cooler can range between 45 and 65 degrees Fahrenheit. A kitchen fridge is usually set around 35 degrees and has lower humidity. The best long term average storage temperature for wine is about 55 degrees. This will store and age wine properly. This is too wine for a kitchen fridge.
For storing red wine, the optimal temperature is 50 to 55 degrees Fahrenheit - not room temperature. So you should store your red wine varieties in a wine cellar or wine refrigerator at that temperature. What is most important is the temperature that the red wine is stored at. Red Wine should be stored at 50-55ºF so it can be stored in a wine rack located in an area kept at this temperature or a wine cellar/cooler or wine refrigerator kept at this temperature.
All you really need is a cool, dry place in your home for your wine cooler, often your basement. If you install one in your kitchen try to keep it away from the stove or other appliances that put out heat (including the refrigerator).
A very good wine like this needs to be in a wine cooler to protect it from heat, light and humidity. A wine cooler provides a stable cool temperature in a dark environment.
Although I am not a wine drinker, I have been told by some of my friends that a wine cooler is nicer because it keeps your wine at just the right temperature. It is your personal preferance though, and if you are happy with the temperature of your wind from the mini fridge then I would just continue to use it.
