The process and the place

Where the sea does its work

A method, a unique site at the heart of Monaco, and operations controlled from start to finish.

Underwater maturation

Four conditions brought together by the sea

Underwater maturation has been explored for several decades. Comparative tastings show that the marine environment influences how products evolve as they mature.

As an indication: for wine, comparative tastings show that six months of underwater maturation can produce an organoleptic evolution comparable to five years of cellar ageing.

  • 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.

The place

A second calling for the Monaco breakwater

ZEPHYR is setting up in the hollow compartments of the Monaco breakwater’s embankment, originally designed to break the energy of the waves.

Without altering their primary function, ZEPHYR gives them a second calling: that of a true underwater cellar.

  • An existing structure

    The cellar makes use of infrastructure already in place: no construction at sea.

  • Maximum security

    No access from the sea, secure access from land and constant camera surveillance.

  • Ideal conditions

    Permanent darkness, stable temperature and natural renewal of the water.

  • Logistics from the quay

    Operations are carried out directly from land: fewer nautical resources, fewer journeys.

Step by step

From project to signed bottle

  1. 01

    The project

    Product, protocol, duration: together, we define the framework of the maturation.

  2. 02

    Preparation

    The lot is prepared and registered before going to sea.

  3. 03

    Immersion

    From the quay, the lot is lowered into the breakwater’s submerged compartments.

  4. 04

    Monitoring

    Throughout the maturation, the lot is monitored and traced; its analysis bottles allow comparative tastings.

  5. 05

    Recovery

    The lot returns to land: each bottle receives its unique number and its immersion certificate.

Duration, protocol, traceability: we will be glad to answer.
