The Hidden Sea

The Hidden Sea is no-nonsense premium wine company making wines that matter for people who care. For every 1 bottle of The Hidden Sea that you buy, we remove and recycle 10 plastic bottles from the ocean.

We want to leave the world better than it was when we came in, and our wines carry a heritage born from the sea.

26 million years ago, South Australia’s incredible Limestone Coast was submerged by a vast ocean that was home to a thriving marine ecosystem.

A series of dramatic ice ages caused the ocean to recede, leaving the area rich with deep limestone deposits containing majestic marine fossils.

Ancient mineralised relics, and an extensive museum of marine life, now lay buried beneath the alluvial soils of this World Heritage site.

One of these relics is the fossilised remains of an ancient whale which contributes to the rich, fertile soil in our vineyard. It also provides a natural and unique filtration system - perfect for growing the grapes that produce our award-winning wine.
