Subsea Estate

At the southwestern tip of Australia, where the Southern and Indian Oceans meet, Subsea Estate—the Southern Hemisphere's first Open Ocean Winery—is pioneering a new frontier in winemaking. Working in partnership with select Margaret River producers, we transform premium varietals through our innovative ocean-crafting process. Our specialised vats rest 20 metres beneath the surface, where consistent temperatures, oceanic pressure, and natural currents create distinctive characteristics that are impossible to replicate on land. This patented process, developed in collaboration with French winemaking innovators Winereef, merges traditional expertise with maritime innovation. The outcome? Limited-edition wines that showcase unique flavour profiles expressing their southern ocean provenance with an elegant and exciting finesse. Subsea Estate stands as a groundbreaking contribution from Western Australia to global wine innovation, where nature's raw power shapes each vintage.
