Cave Monge-Granon is a four-generation family winegrowing located in the heart of Diois Valley nested between the Rhone Valley, the Drôme Provençale and the majestuous Vercors mountain (Beginning of the French Alps). Thanks to their organisation, they are vinifiying and selling over 700,000 bottles of wine a year. They produce mainly AOC wines and a unique sparkling wine :

-Clairette de Die tradition (Méthode Ancestrale, low alcohol,  8% alc. from Muscat and Clairette grapes)

-Crémant de Die brut (Clairette and Aligoté grapes, the rarest of all french crémant)

-Chatillon en diois (still wine in white, rosé and red, a small, high-quality mountain appellation at the foot of the Vercors Massif).

The winery is also HVE 3 certified, and a significant part of its production is certified organic and biodynamic via DEMETER.
