Souvignargues is located in the easternmost part of the Coteaux du Languedoc and is part of the sub-region known as the Terres de Sommières. Thierry Forestier has selected vineyard plots with old vines (often head-pruned) many of which are in particularly cool micro-climates. Nearly a third of his vineyards are planted to Aramon, a much neglected, historic and local grape variety. His Aramon vines are at least 100 years old.

Thierry farms without the use of herbacides or insecticides, using only copper and sulphur to fight mildew. All of his vinifications are done with indigenous yeasts and without any intervention. The wines are bottled unfined and unfiltered.

The Anathème Blanc is produced from a .5 hectare vineyard of 70 year old Ugni Blanc. This north facing vineyard is among the last in the Languedoc to be harvested. The picking is done manually with a selection (tri) made in the vineyard. Fermentation is carried out in stainless steel tanks without intervention and can last (as it did in 2011) for up to eight months. No sulphur is used during the process. The wine is bottled without fining or filtering and a very small dose of sulphur is used at this time. The 2011 vintage is 11.5% alcohol.

The cuvee Vertigo is composed of 60% Syrah from 20 year old vines grown in a cool micro-climate and 40% Carignan from a plot of 80 year old head pruned vines. The two grape types are fermented separately with whole berries being put into cement cuves where they begin their fermentation semi-carbonically. The juice is kept in contact with the skins for up to 4 weeks to extract color and flavor. The wines are drawn off the skins and assembled and then mature for 6 months in cement. Bottling is done without fining or filtering.
