are subterranean structures for the storage
and aging of wine
. They are an integral component of the wine industry world wide. The design and construction of wine caves represents a unique application of underground construction
The storage of wine underground offers the benefits of energy efficiency and optimum use of limited land area. Wine caves naturally provide both high humidity and cool temperatures; key to the storage and aging of wine
