The “caves” or family wine cellars, so characteristic of Laguardia, Rioja Alavesa, Spain. Wine caves are subterranean structures for the storage and the aging of wine. They are an integral component of the wine industry worldwide. The design and construction of wine caves represents a unique application of underground construction techniques. Like any other natural foods, wines are perishable. If you place them in places where temperature and humidity tend to fluctuate, they will spoil. Even a lenient temperature spike can negatively affect wine. That's why most wine enthusiasts own wine cellars, which can manage both temperature and humidity levels.
