Monaco’s underwater cellar
The sea does not transform a product, it shapes it.
Deep within the Monaco breakwater, ZEPHYR matures premium wines, champagnes, spirits and condiments beneath the sea.
Underwater maturation
What the sea brings
The sea naturally brings together singular conditions, which accompany the product’s evolution throughout its immersion.
Stable temperature
Far from the swings of the open air, the temperature changes little, and slowly.
Total darkness
In the submerged compartments, no light reaches the bottles.
Natural pressure
The pressure of the water bears on every bottle, day and night.
Constant movement
The movement of the sea accompanies the product throughout its maturation.

By ZEPHYR
Your craft, the time of the sea
Maturing an existing cuvée, adapting a product or creating a range designed for the sea: every collaboration is built to measure. The product remains yours; it receives the by ZEPHYR signature, a unique number and an immersion certificate.

The place
At the heart of the Monaco breakwater
The hollow compartments of the breakwater’s embankment, designed to break the energy of the waves, become a true underwater cellar. An existing structure, operated from the quay, under constant surveillance.
