Spain features diverse underground wineries for enotourism

Spain offers a variety of underground wineries, known as calados, which are excavated beneath towns to maintain consistent temperature and humidity for wine production and storage. These subterranean galleries, often located under streets, plazas, or ancient houses, serve as significant cultural and enotourism sites.

These architectural spaces function as natural climate control systems, using earth and stone walls to insulate against extreme heat and cold. Many of these sites now operate as museums or tourist attractions, allowing visitors to explore labyrinthine networks that preserve traditional winemaking methods and regional heritage.
