Underwater Treasure: The Wine Revolution of Crusoe Treasure Winery in the Brave Cantabrian Sea

Beneath the waters of the untamed Cantabrian Sea, where nature reveals itself in all its power, Bodega Crusoe Treasure has developed a revolutionary aging process: underwater storage. Thanks to a pioneering vision and years of research in conjunction with the Excell Ibérica Laboratory, they have designed unique concrete and steel structures capable of withstanding the ocean's storms and providing the wines with an extraordinary maturation environment.

The Cantabrian Sea as a Differentiating Factor

The extreme conditions of the Cantabrian Sea make it an unparalleled natural laboratory for underwater wine aging:

Stable and controlled temperature by the ocean, without the thermal fluctuations of a land-based winery.

Total darkness, which protects the wine from light degradation.

Marine pressure and lower gravity, which influence the evolution of the wine's structure and texture.

Constant and dynamic movement of water, allowing for unique micro-oxygenation without the need for barrels.

To make this aging process possible in such a challenging sea, Bodega Crusoe Treasure designed and installed submerged concrete and steel structures capable of withstanding currents, tides, and the impact of waves. These innovative underwater cellars guarantee safe and effective storage, achieving a wine evolution impossible to replicate on land.

Scientifically Supported Results

Underwater storage is not only an innovative concept, but a process backed by science:

More than 15 years of studies conducted by the Excell Ibérica Laboratory, together with the University of the Basque Country and the University of La Rioja, have demonstrated that the marine environment contributes sensory and qualitative differences to wine.

Blind tastings with experts have confirmed that the wines treasured under the sea feature:

Greater color intensity and stability.

More complex and fresh aromas, with a predominance of fruity, floral and mineral notes.

Silky and balanced texture, with a perfect integration of acidity and body.

Sparkling Wines: A Unique Challenge Overcome in the Cantabrian Sea

Crusoe Treasure Winery has gone even further by carrying out, for the first time in the world, the secondary fermentation and aging of sparkling wines on lees at the bottom of the sea. Marine kinetics accelerates yeast autolysis, improving carbon integration and providing exceptional creaminess on the palate.

Conclusion: Innovation, Nature and Excellence in Every Bottle

The underwater treasure of Bodega Crusoe Treasure, forged in the waters of the Cantabrian Sea, is a milestone in modern winemaking. Its combination of extreme nature, structures designed to withstand the ocean, and meticulous oenological monitoring has resulted in wines unique in the world. Spain, once again, positions itself as a benchmark in the production of innovative, high-quality wines, taking oenological excellence to new depths.

With these 3 simple steps, we'll show you how to correctly open our bottles.
1. Use a Crusoe Treasure hammer , corkscrew, or other blunt metal object to tap the sealing wax protecting the mouth of the bottle. We recommend covering it with a handkerchief or napkin before tapping the sealing wax to prevent the pieces from scattering.
2. Remove any remaining sealing wax and remove the cork from the bottle.
3. Once the cork is removed, thoroughly clean the mouth of the bottle again with a napkin before serving the wine. [+]

Sometimes, when opening a bottle of red wine, you're likely to find some crystals adhering to the cork. These crystals don't affect the quality of the wine or its consumption. These " wine diamonds " form when tartaric acid, a natural component found in grapes, combines with the chemical element potassium or calcium bitartrate under cold, turbulent conditions, such as ocean waves, forming a crystalline salt that bonds with the cork. [+]

The sealing wax that covers the mouth of the bottle is used to prevent the area from being colonized by marine life. After going through the underwater storage process, the sealing wax becomes very fragile and breaks easily (during transport or handling). This fact does not affect or damage the quality of the wine. The sealing wax is only necessary during the underwater process.

Our winemaker, Antonio T. Palacios, affirms that the wines are ready to drink from the moment you uncork the bottle. This wine develops very well in the glass; the characteristics of the wine change from the moment you open the bottle until a few minutes later. [+]

Yes, they are vegan. We are not certified vegan, but we do not use any animal-derived clarification during our winemaking process (wine clarification is a process carried out to remove any remaining impurities from the grape or yeast prior to bottling). [+]

Generally speaking, preserving one of our underwater wines isn't much different from preserving a wine aged on land, which makes it easier to consume. But perhaps, as a wine lover or as a consumer of new and different experiences, you've wondered how to preserve it without losing all its authenticity. Here are some recommendations: [+]

Today, the analyses performed by Antonio T. Palacios indicate that under these conditions, red wines can last up to 10 years without problems, and white wines between 5 and 7 years. Beyond that time, the difference depends on the wine and how we stored the bottle. Our recommendation: the wines are excellent for consumption today, but if you prefer, you can store them for 5 years, and the wine will improve naturally. [+]
