A wine cellar is a storage room of wine in a bottle or barrel, or more rarely in a carboy, amphorae, or plastic container. In an active wine cellar, important factors such as temperature and humidity are maintained by climate control systems. In contrast, the passive wine cellar is not climate controlled, and is usually built underground to reduce temperature changes. The wine cellar on the ground is often called the wine room, while a small wine cellar (less than 500 bottles) is sometimes called a wine cellar. . The housekeeping department responsible for storage, care, and wine service in a medieval mansion is termed as butter. The large wine cellar dates back more than 3700 years.

The wine cellar protects alcoholic beverages from potentially harmful external influences, providing darkness, constant temperature, and constant humidity. Wine is a perishable natural food product produced from fermented fruits. Left exposed to heat, light, vibration or fluctuations in temperature and humidity, any type of wine can be detrimental. When stored well, wine not only preserves its quality but many actually improve the aroma, taste, and complexity when ripe. Depending on the level of sugar and alcohol, the wine is more or less sensitive to temperature variations. The more content of wine, alcohol and/or sugar, the less sensitive to the temperature difference.

Terms
The wine can be stored satisfactorily between 7-18Ã,  ° C (45-64Ã,  ° F) as long as there are variations in stages. Temperature 13Ã, ° C (55Ã,  ° F), as found in the caves used to store wine in France, is ideal for short-term storage and long-term wine aging. Note that grapes are generally ripe differently and slower at lower temperatures than higher temperatures. When temperature changes are significant, 14 degrees or more, it will cause the wine to breathe through the cork which significantly speeds up the aging process. Between 10-14  ° C (50-57  ° F), the wine will be of normal age.
Active versus passive
The wine cellar can become active or passively cooled. The active wine cellar is very isolated and needs to be built properly. They require a special wine cell and cooling conditioner to maintain the desired temperature and humidity. In a very dry climate, it may be necessary to actively humidify the air, but in most areas it is not necessary. A passive wine cellar should be located in a cool, moist natural area with variations in seasonal temperatures and small diurnal - for example, basements in a temperate climate. Passive warehouses may be less predictable, but there is no cost to operate and are not affected by power outages.
The moisture debate
Some wine experts debate the importance of moisture for proper wine storage. In the Wine Spectator, author Matt Kramer notes the French study which states that the relative humidity in the bottle is kept 100% regardless of the used closure or bottle orientation. However, Alexis Lichine says that low humidity can be a problem as it can cause an organic cork to dry prematurely. An inch of gravel that covers the floor periodically sprinkled with a little water is recommended to maintain the desired moisture.
