In 1992, the oenologically trained Louis Barruol took over the property from his father Henri Barroul. Since 1570 the property has been inherited by Louis Barroul's ancestors and Barroul is the 14th generation at the property.
Well-preserved wine cuves from the production of wine from Roman times can be seen in the form of carved "tanks" in the limestone cliffs where the cellar is situated today. There is therefore evidence to denote the domain as the oldest in Gigondas - perhaps in the Rhine Valley. The very historically conscious and knowledgeable Louis Barroul also believes that he is able to name the retired Roman legionarian Cornelius who must have founded the winegrowing property in 109 a C

The 15 ha. AOC Gigondas, belonging to the property, is located around the domain and encircles the medieval Chapel Saint Cosme giving name to the place.
Although the parcels are gathered in a small area, there are quite different soil conditions, as the vineyards are located somewhere where the rejections from Dentelles de Montmirail cross each other.
The average age of the vines is 60 years. The grapes are not de-stemmef for the Gigondas vines and undergo a relatively long maceration period, are aged in partly new barrels and are bottled without filtration.
In 2007 a major renovation of the ageing cellar was made.

In 2013 Barroul acquired a domain of 10 ha. in Violès. From 2016, white wine was produced from newly planted Viognier and Picpoul and in 2017 a white wine based on Marsanne.
In 2019 Louis Barroul bought Chateau Rouanne in Vinsobres. As he had control over the winemaking in 2018 he made his first vintage of Vinsobres then
At present (November 2017), wines from this area not presented in details at the domain's website; However it is stated that in 2017 prepairing for biodynamic cultivation methods for these fields is being undertaken, which is also widely practiced in the vineyards of Gigondas.
Since 2013 the Gigondas vineyards have been certified agriculture biologique.
