Our expertise


Located in Entre-Deux-Mers, on the right bank of the Gironde, a large part of our vineyards overlook the river. Surrounded by the Garonne and Dordogne rivers, our weather is temperate oceanic. Wind and sun regulate the humidity.

Weather plays an important role in favoring the growth and quality of the grapes.


Our soils are mainly clay-limestone. This type of soil is very fertile and easy to work. It retains water, so the vines are well drained and the soil heats up quickly.

The result is a balance of heat and water for the vines, a balance that is also reflected in our wines.


We grow the typical Bordeaux grape varieties: Cabernet Sauvignon, Merlot, Cabernet Franc and Malbec for the reds. Sauvignon blanc, Sauvignon gris and Sémillon for the whites. Planted in 2022, new varieties such as Carmenère, Petit Verdot and Castets will complete the aromatic palette of our estate wines from the 2025 harvest.

The vineyard


All the work carried out during the vine's vegetative cycle is designed to guarantee the production of quality grapes and the health of the plant. This work includes soil maintenance, the use of organic fertilizers, and specific pruning of the vines called “Double Guyot”.


Our vineyard is constantly evolving, with “racotage” - the replacement of vines - deep soil cultivation, and regular investments in our production equipment to facilitate work while preserving the environment.


Harvesting is mechanized to ensure optimal ripeness, avoiding the hot hours of the day to preserve the freshness of the grapes, and reducing the time between harvesting and vatting to limit oxidation.

The winery


Building on our 250-year heritage, we have constantly developed our cellars and invested in modern equipment to vinify our Entre-deux-Mers wines while preserving their character.


We work closely with oenologists to guarantee the quality of our blends.

For red wines, we use a variety of tanks and barrels to obtain different profiles, while white wines are aged in stainless steel tanks to preserve their freshness.


Our bottling process is completed on site, and we have storage space available to meet our customers' needs.

Our commitment


Since the 2019 vintage, we have obtained Level 3 High Environmental Value certification.


This project has enabled us to enhance our commitment to improving our environmental performance by complying with precise specifications. This certification is a voluntary approach that highlights the preservation of biodiversity through controlled management of fertilization, water resources and a defined phytosanitary strategy.


The fact that we have obtained Level 3 certification means that we can communicate on our approach with the support of conclusive results.

Tailor-made packaging


Being equipped with our own bottling line means we can control the evolution of our options.


That's why we're able to offer customized bottle packaging with the same responsiveness as a conventional order.


Half-bottles, magnums and wooden cases hold no secrets for us.


The loyalty of our employees, the internationalization of our bottling processes and our willingness to work with local suppliers enable us to guarantee real efficiency in order processing.


Guaranteed collection within a maximum of 15 days, from validation of dry matter.


Trust and continuity are the watchwords that drive our company, and are also reflected in our commercial approach. Currently present on 5 continents.
