EGIATEGIA has been a pioneer in underwater vinification since 2007: a patented method that is unique in the world.

UNDERWATER VINIFICATION

In 2007, Emmanuel Poirmeur filed a patent for the vinification and ageing of wines underwater. This new process seeks out the physical conditions required for vinification: pressure, darkness, thermal inertia and, above all, agitation due to pressure variations linked to the tides.

Since 2008, EGIATEGIA has been carrying out fermentations in tanks in the Bay of Saint-Jean-de-Luz, in the Basque Country , at a depth of 15m. The stage carried out here is a second alcoholic fermentation, otherwise known as "prise de mousse" or "tirage" in sparkling winemaking methods. This process highlights the crucial role of yeast in the winemaking process

Indeed, as in all wines, yeast plays a fundamental role, one that is often overlooked or even unjustly neglected. Its metabolism during alcoholic fermentation not only transforms sugar into alcohol, but is also at the origin of numerous so-called secondary aromas... Once alcoholic fermentation is complete, the autolysis of these same yeasts in the form of increasingly fine lees releases other aromatic compounds.

In the underwater environment, with its extraordinary physical conditions, yeast metabolism and autolysis are modified. As a result, new aromatic profiles are revealed that would not appear on land under more conventional conditions.

The originality of this concept also lies in the fact that the fundamental stages of wine-making are carried out in tanks under underwater conditions, rather than simply aging finished wine in bottles. These specially-designed tanks have been specifically developed and patented for this purpose, to ensure a completely safe balance of pressure between the outside (the ocean) and the inside (the wine).

This pioneering and extraordinary winemaking method reveals aromas that would not otherwise develop spontaneously using this underwater process.
EGIATEGIA: WINES WITH AMAZING NOTES REVEALED BY THE UNDERWATER ENVIRONMENT

The wine is made from grape varieties with selected aromatic profiles and vinified a first time for immersion.

Indeed, as with great sparkling wines, grape selection, pressing and initial fermentation are three sensitive preliminary stages that are key to the rest of the winemaking process. Just as not all wines improve with barrel ageing, not all are enhanced by immersion.
