Located in the beautiful Plentzia Bay, this is the first underwater wine cellar in the world! Here, witness how the science of aging wine under water is being perfected, and discover how this is revolutionizing the industry. Learn how grapes are selected to be suitable for the underwater cellar and aged in bottles and barrels 20 meters beneath the sea. The weightlessness, water pressure, darkness, and gentle rocking movement of the ocean result in wines that are smoother and rounder in flavor. During your exclusive visit, enjoy a boat excursion to the underwater cellar. Then, enjoy a wine tasting of two wines, paired with a pintxos degustation.
