80% Carignan/20% Grenache. The Carignan vines average 40 years in age, with some of them being up over 100 years old, and are planted on clay-limestone soils. The fruit is sustainably farmed and harvested partly by hand and partly by machine. The Carignan remains in whole clusters and goes through a full carbonic maceration in tank. The Grenache is destemmed and is macerated for 3-4 weeks in concrete vats. Fermentation is with selected yeasts. The two varieties are blended and aged in tank. The wine is bottled with a light, non-sterile filtration and a very small dose of sulfur. 

 "Les Hérétiques" is a nod to the Cathars, a heretical Christian group based in the Languedoc but wiped out by order of Pope Innocent III in 1208 in response to the murder of a papal representative by a Cathar supporter near Minervois. The castle which is the home of Château d'Oupia dates back to this time as well. The striking label was designed by Joe Dressner himself.
