Producing wine in the Sea – a unique investment opportunity

At the southwestern tip of Australia, Subsea Estate is pioneering the world’s first open-ocean winery.

Combining Margaret River’s premium wines with Winereef’s patented subsea fermentation process, Subsea Estate crafts unique ocean-aged wines infused with the power and rhythm of the sea.

Their team consists of innovators from the seafood industry and leading wine pioneers from both Australia and abroad who are dedicated to discovering new depths of premium wine. At their licensed 5-hectare Subsea Estate off the coast of Augusta, they have access to idyllic and adventurous waters as we explore the winemaking potential of the pristine marine environment. This endeavour is supported by the expertise of French winemakers, Winereef International, who have spent over 17 years perfecting their world-first subsea winemaking process.

By combining our experience and adventurous spirit with the beautiful unpredictability of the Southern Ocean, we're at a new frontier, striving to deliver a fresh wine experience that remains true to the quality emblematic of Australia's winemaking industry.

This partnership between Rare Foods Australia and Winereef International represents a new frontier in premium wine innovation and storytelling.

A rare, early-stage opportunity exists to invest in a world-first wine innovation. Subsea estate are looking for investment to help them grow and expand their unique wine and food experience.

Expansion plans include:

• Confirmed partnership trial with Treasury Wine Estates (2026)

• Development of Hillarys Marina Concept Store in Perth.

• Unique wine & premium seafood experience –Subsea Estate stores in harbourside locations

• Future new Subsea Estate winery/seafood restaurant at Augusta Harbour (Lot B)

• Future Australian Winereef locations: Sydney, Melbourne, Adelaide, Hobart

• Vision: vertically integrated ‘ocean-to-glass’ global brand

The business is highly scalable in a short timeframe. It can adapt quickly to changing consumer preferences and trends. The capital expenditure required to expand and produce large volumes of premium wines is attractive, especially since it eliminates the need to own vineyards or wineries. The local Margaret River winery industry has all the supporting infrastructure to support rapid growth as demand increases.

This is a unique and astute investment opportunity available at a very early stage.
