Wine storage began in the underground caves of Europe. These caves provided the consistent storing conditions that allowed wine to age at an elegant pace. By convention, these conditions have become the standard for modern wine cellars: The ideal wine cellar temperature range is 10~16 degree centigrade and 55-75% relative humidity.
A wine cellar is a storage room for wine in bottles or barrels, or more rarely in carboys, amphorae, or plastic containers. A balance of temperature and humidity is critical for the proper storage and aging of wine. Temperature affects the rate of maturation while the right humidity keeps corks in good shape. Excess moisture can lead to mold or fungal contamination while a room that is too dry can cause corks to shrink, leading to the oxidization of wine.
