Bottles retrieved after underwater storage

This Thursday, 426 bottles of the Vinocap 2025 wine vintage, submerged in the Mediterranean Sea in December of the previous year, were retrieved from a secret maritime location. The bottles had been placed in sealed pouches and locked in a cage before being submerged for over ten months.

Wine experiment compares underwater and traditional storage

The operation was conducted by the association La Route des Vignerons et des Pêcheurs, which aimed to compare the effects of underwater preservation with traditional aging methods in wine cellars. The selected wines are those known to age well, where storage conditions significantly influence the final product.

Mediterranean as a natural cellar

Gwendoline Chaudoir, president of the Hérault Méditerranée agglomeration, noted that the Mediterranean Sea acts as a natural cellar, maintaining a stable temperature. This stability may influence how the wine ages during its time underwater, similar to how traditional cellars preserve wine.

Comparing two aging methods

Some of the winemakers involved in the experiment have kept a twin bottle of the same wine in a traditional cellar. This allows for a direct comparison between the effects of underwater aging and conventional aging methods. Chaudoir expects the results to be "rather surprising."

Promoting local vineyards and wine

Beyond the scientific curiosity, the initiative aims to raise awareness of the wines produced in the region and the work of local winemakers. Chaudoir described the experience as a symbolic embrace between the land and the sea, highlighting the connection between vineyards and the Mediterranean.

Challenges in the wine industry

Pierre Quinonero, president of the association La Route des Vignerons et des Pêcheurs, emphasized that the region has a dynamic wine industry but faces significant competition in foreign markets. He noted that the region produces about a million hectoliters of wine annually, far more than can be consumed locally, leading to a strong reliance on international sales.
