Wine caves 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 techniques.

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.

While natural caves have been utilized for cool storage and aging for millennia, the creation of caves exclusively for wine started in California. The first man-made wine caves date back to the mid nineteenth century in Napa Valley.
