Picture of Saint Croix du Mont

The winegrowing area of Sainte-Croix-du-Mont itself, looks over the right bank of the Garonne and rises about one hundred meters above it. It occupies a good part of the total area of the commune and covers 450 hectares.
Many tributaries of the Garonne crisscross the area. On late summer mornings, condensation forms and envelopes the vineyards. In the the afternoon sun heat warms the grapes, providing the perfect conditions for the formation of Botrytis cinerea, a fungus that creates noble rot.

The vines, which are over 30 years old, enjoy a privileged south-south-east exposure, on a clay-limestone soil, enriched with marine fossils. Indeed, huge beds of fossilized oyster accumulated there in the Tertiary period, in the Early Miocene (beginning of the second part of the Tertiary), about 20 million years ago, in a lagoon next to a slightly raised area already present at the time, which still provide exceptional amounts of iodine. Light formations that cover the territory of Sainte-Croix-du-Mont include alluvial terraces, limestone or marl substratum, and a fairly general covering of light sediment of a more or less silty colluvium.
These clay-limestone and gravel plateau enable the white grape varieties of this AOC to flourish and produce high quality.
