Tradition and Terroir

Mare Santo is born in the green hills of Collio, where Mediterranean air meets Alpine wind.
This natural contrast caresses and challenges the vines, shaping grapes with remarkable complexity.

Our grapes grow on mineral-rich soil, nurtured by climate and time.
They are hand-harvested with care, following authentic techniques and traditional recipes, passed down through
generations in our small, private winery - where quality always comes before quantity.

This is where Ribolla Gialla - known locally as Rebula - continues to thrive. A grape rooted in Roman history, once
praised by poets and emperors alike.
Even Boccaccio listed Ribolla among the reasons “God invented the sin of gluttony.”

We don’t mention it by chance: Ribolla is the soul of Mare Santo Cuvée Prestige, blended with Chardonnay to create depth, tension, and quiet elegance.

Handcrafted, then Submerged

We don’t mass-produce.
Every grape is hand-picked, and only the finest make it to bottle.
Then, something unique happens: we age our wines beneath the Adriatic Sea, 20 meters deep, for 12–24 months.

“We return the wine to nature.
And nature gives back.”

Why the Sea?

Slovenian winemaker Igor Tomažič revived an old custom:
cooling bottles in streams. Forgotten bottles tasted better.
So he asked - what if the sea could age wine?

Since then, Mare Santo has evolved underwater. Sea currents
keep it alive. Minerals pass through the cork. Flavor deepens.

“It started as an idea. Now it’s a global patent.”

From the Hills of Goriška Brda

Cuvée Prestige blends Rebula (structure)
and Chardonnay (softness)

Rosé uses only Pinot Noir, hand-harvested
from select vineyard.

Crafted by Nature

Mare Santo is shaped by more than hands -
It’s built on contrasts:
Sun and salt. Wind and calm. Depth and stillness.

“We follow nature. And nature rewards us with something unforgettable.”
