The domaine extend on differents named places : La Coulette, Cantagrils, Puech Redon et le Mas de l’Olivier. Altitude 70 meters.

The AOC Picpoul vines are planted near the pine-forest
and therefore benefit from its protection from the north
and south winds : the "Mistral" and the "Marin".
The red AOC vines are on the top of La Coulette, named
"la Boule" because of the scrubland which has no
protection from the wind ; it looks like a bald head.
