Notre terroir

Our terroir is the starting point of our wines’ identity.
Its richness, the choice of grape varieties, and the exposure of the vineyard plots form its foundations.


Knowing how to listen to and reveal the terroir is to lay the first stone of a wine with character and quality.

Clay-limestone soil

Located on the right bank of the Gironde estuary, our clay-limestone terroir forms the foundation of our vineyard.

These soils, composed of a 40 to 60 cm layer of clay resting on a more or less friable limestone subsoil, are particularly well suited to Merlot, where it expresses generous fruit, beautiful roundness, and velvety tannins.

In response to climate change and rising summer temperatures, we are also developing Cabernet Sauvignon on these plots. This later-ripening grape variety delivers high-quality results here. Our goal is to gradually increase its planting so that it represents around 20% of the vineyard on these soils.

Clay-sandy soil

Our terroir also includes clay-sandy soils, which are generally cooler and retain more moisture. Thanks to carefully selected rootstocks and controlled drainage, Merlot fully expresses its character here, producing supple wines with a fine structure, particularly in dry vintages, as we have regularly observed since 2003.

 

In areas where the proportion of sand is higher, we have chosen to plant Sauvignon Blanc in order to produce wines with great aromatic finesse.

Another part of the estate lies on deeper soils composed of clays with yellow or bluish hues, depending on the plots. This type of terroir is particularly well suited to Merlot. The wines produced from it are generally less marked by fruit, but offer a denser and more pronounced tannic structure.

Blended with the wines from our clay-limestone soils, they allow us to craft cuvées that are more complex and harmonious.

We are also replanting Malbec there, also known as Côt. The estate’s former winegrowers already cultivated it, and their experience had shown that this grape variety expresses itself very well on this type of soil.
