Some people love wine so much that they buy a bundle and then need a special place to put it. One option is a wine rack that can hold quite a few bottles, but another is to look at custom wine cellars. A cellar is traditionally an underground space, but a modern one could simply be a walk-in fridge with compartments for wine and a cooling mechanism that is very efficient and designed to preserve wine flavors.
Wine cellars work by using the ground temperature to keep wines cool and fresh. The higher the latitude, the cooler the ground will be. Cellars are also dark, which is great for protecting wine from sunlight degradation. A cellar might have a temperature between 40 and 50 degrees Fahrenheit depending on the local climate. This mild temperature keeps wine cold enough to drink without further chilling and also permits long term mellowing at a temperature slightly warmer than a refrigerator.
