Cellar is a room, or set of rooms, for the storage of food, fuel, etc., wholly or partly underground and usually beneath a building.

Wine Cellar

Storage of wine is an important consideration for wine that is being kept for long-term aging, Wine is one of the few commodities that can improve in flavor and value with age, but it can also rapidly deteriorate if kept in inadequate conditions.

Wine cellars protect alcoholic beverages from potentially harmful external influences, providing darkness, constant temperature, and constant humidity. Wine can be stored satisfactorily between 7–18 °C (45–64 °F) as long as any variations are gradual. A temperature of 13 °C (55 °F), much like that found in the caves used to store wine in France, is ideal for both short-term storage and long-term aging of wine.

If wine is stored in conditions that are too dry, the cork will shrink and cause leakage. Too moist, and mold and contamination may occur. Climate Controlled Wine Cellar maintains moderate humidity levels (55%-75%) to avoid these problems and assist in the optimum wine development conditions.

地窖

地窖可指一个房间或一组房间，用于储存食物，燃料等，位置通常是整体或部分建在建筑物地下。

酒窖

怎样长期储存葡萄酒是保存葡萄酒的重要考虑因素，葡萄酒是少数能够随着储存时间增加而提升口感和价值的商品之一，但如果储存在不适当的条件下，它也会迅速变质。

酒窖可以保护酒精饮料免受潜在的有害外部影响，提供一个黑暗，恒温和恒湿的环境。葡萄酒的适宜储存温度在7-18°C（45-64°F）之间，但需保证任何温度的任何变化都是逐渐的。13°C的储存温度（55°F）与法国用于储存葡萄酒的洞穴非常相似，非常适合短期储存和葡萄酒的长期熟化。

如果葡萄酒储存在过于干燥的条件下，软木塞会收缩并导致泄漏。太潮湿，可能会发生霉菌和污染。恒温控制的酒窖的湿度为55％-75％，这样可以避免这些问题，并帮助提供更好的葡萄酒储存条件。
