Clos Culombu was founded in the mid-1970s by Paul Suzzoni, and by the mid-1980s his brother Etienne has run the domain. The vineyards cover less than half the 95 hectares that make up the estate.

The soils in this area are made from granite, with some clay rich pockets. The micro-climates of the vineyards are strongly influenced by the sea, which is only 2 kilometres away and the nearby mountains.
