Santorini underwater wine is a fascinating innovation in winemaking, where bottles are submerged off the coast of Santorini, Greece. This unique aging process, primarily conducted by Gaia Wines, involves placing wines at a depth of 25 meters in the Aegean Sea. The submerged bottles develop distinct characteristics, including smoky aromas and rounded flavors, due to the unique underwater environment. This method combines traditional winemaking with innovative aging techniques, creating a product that captures the essence of Santorini’s volcanic terroir and maritime influence.
What is the History Behind Santorini Underwater Wine?

The concept of underwater wine aging in Santorini is a relatively recent innovation, pioneered by Gaia Wines. This innovative approach to winemaking began as an experiment to explore how the underwater environment might affect the aging process of wine. The idea was inspired by the discovery of well-preserved wines in shipwrecks, which demonstrated the potential of underwater aging.
Gaia Wines, known for their commitment to the indigenous Assyrtiko grape variety, decided to take this concept and apply it to their “Thalassitis” wine. The name “Thalassitis” itself is derived from the Greek word for “sea,” making it a fitting choice for this underwater experiment.
The first batch of underwater-aged wine was submerged in 2009, marking the beginning of this unique winemaking approach in Santorini. Since then, Gaia Wines has continued to refine and expand this process, gaining international attention for their innovative technique.
Where Exactly are the Underwater Vineyards Located in Santorini?

The underwater wine aging in Santorini takes place in a specific location:
- Coast: Off the east coast of Santorini
- Depth: 25 meters (approximately 82 feet) below the surface
- Method: Bottles are placed in metal cages to protect them during the aging process
This location was chosen for its ideal conditions, including consistent water temperature and pressure, which contribute to the unique aging process of the wine.
How Does the Underwater Aging Process Work?
The underwater aging process for Santorini wine involves several key steps:
- Wine Selection: Gaia Wines uses their “Thalassitis” wine, made from the Assyrtiko grape variety.
- Bottle Preparation: The wine bottles are specially sealed to withstand underwater pressure.
- Submersion: Bottles are placed in metal cages and submerged to a depth of 25 meters.
- Aging Period: The wines are left underwater for a specific period, typically several months.
- Retrieval: After the aging period, the bottles are carefully brought back to the surface.
- Analysis and Tasting: The wines are analyzed and tasted to assess the effects of underwater aging.
This process results in wines with unique characteristics, including:
- Smoky aromatic dimensions
- Hydrocarbon notes
- Rounded character
- No signs of oxidation
What Makes Santorini Underwater Wine Unique?
Santorini underwater wine stands out for several reasons:
- Terroir Influence: The volcanic soil of Santorini imparts a distinct minerality to the wine.
- Grape Variety: The use of the indigenous Assyrtiko grape, known for its high acidity and mineral character.
- Underwater Aging: The unique environment of the Aegean Sea affects the wine’s development.
- Pressure and Temperature: Constant pressure and cool temperatures at depth contribute to the wine’s character.
- Limited Production: The underwater aging process results in a limited number of bottles, making it a rare product.
Can Visitors Experience Santorini Underwater Wine Tasting?
While the aging process occurs underwater, tasting experiences are typically conducted on land. Here’s what visitors can expect:
- Tasting Location: Gaia Winery or select locations on Santorini
- Wine Presentation: Winery staff explain the underwater aging process and its effects
