Although the area east of Cairanne and north of Gigondas is relatively small, the landscape and soil types are by no means uniform. In the north, the vines are planted on southern slopes, some of which are relatively steep, up to 360 metres above sea level. Here, on a subsoil of mostly limestone and marl, the finer and more complex wines of the region are produced. South of Rasteau, there are flatter terraces at 120 to 160 meters above sea level. The soils alternate between clay, limestone and marl. Wines from the lower part tend to be a bit more rustic and broad-shouldered than their northern relatives.
