Beginning of the walkway :

In the Marnes country


The “Marnes” is a type of sandstone common to the area, very crumbly and soft to work with it is ideal for vinestock.


This walk delights with views typical of the Diois landscape and the marnes sandstone planted with vines.


Elevation +/- 70m / age over 4 / duration 50mns
The path goes through the district of Barsac in the heart of the Diois vineyards and is perfect for those interested in geology. The terrain is made of ancient sedimentation, the layers of which are revealed through constant erosion over time. When the mountains emerged from the sea, the earth’s crust thrust up a 3000m high dome at the centre of the circular rock formation of Vercheny. The waters then created ravines and cleared each layer forming what we see today. The “marnes” are a mixture of clay and limestone and are of excellent quality for growing grapes on, most notably the Muscat variety which reveals its exquisite aromas.
The walk goes past the village houses and proceeds to the hamlet of Meyries at the foot of the “cirque (circus) marneux”, the shades of which range from beige to dark grey.


And not far away take the time to visit…
The 11th century monastery of Sainte Croix and its botanical garden, the village of Pontaix and the castle ruins, Aurel and the impressive “Butte de l’Aigle” (the Eagle Tip) mountain.
In Vercheny, Isabelle Jacquet’s art studio for paintings, sculpture and engravings
In Saillans, Galerie Morin and Salomé, exhibitions, paintings, ceramics, hand-blown glass and sculpture.
In St. Nazaire le Désert, Galerie D’ici et d’ailleurs (From here and elsewhere) exhibitions and sale of local arts and crafts as well as foreign.


Come and discover the 7 other “Clairette Walks” and enjoy the glorious landscapes!

The maps for each walk can be found at the Tourist Offices.


The vineyards of the Diois in South-eastern France cover nearly 1600 hectares all along the river Drôme in a beautifully conserved landscape where the clement Mediterranean climate meets the alpine air. The river flows through the mountains where the vines make way to fields of lavender and fruit trees. This combination is ideal for the production of charming and surprising wines.

AOC Clairette de Die Tradition

Legend recounts that Clairette de Die was come upon by accident. According to the writings of the Roman writer, Pliny the Elder, one winter, the Voconce people of Gaul (the ancestors of the inhabitants of the Diois), forgot about some amphora containing wine. When the spring came and the amphoras were rediscovered they found a delicious sweet and sparkling liquid in them.


The notion of “terroir”, meaning “the land”, is of prime importance to French rural and agricultural tradition. It gathers together in one term the life, work and produce that the land has provided for centuries, giving France its reputation for a people very much attached to their way of life and the protection of their delightful and stunning countryside.

The Diois is situated inbetween the Alpes and Provence and is therefore one of the highest wine-producing regions of France. The vines in the foothills of the Vercors reach an altitude of 700m and are well protected from frost. The clay and lime soil retains the rainwater very efficiently and so even in the driest periods the vines do not suffer from drought.


Clairette de Die Tradition.

The Clairette de Die Tradition is the main wine produced by the growers in the Diois and is considered to be the jewel of valley.

It is made using the “Méthode Dioise Ancestrale” which is specific to Clairette and is the natural process for making sparkling wine with no added sugar.

During fermentation some of the sugar in the must is preserved by using the cold. The wine is then bottled and the natural sugar and yeast contained in the grapes cannot escape, thus the alcoholic fermentation can start again and will naturally end when the stocks of yeast have disappeared.

The carbonic gas produced at this stage is what makes it a sparkling wine.

Consequently the “Méthode Dioise Ancestrale” requires technique, savoir-faire and finesse in order to produce a unique and elegant wine with subtle aromas and a low alcohol content.

Clairette de Die Brut

The Clairette de Die Brut is only made from the clairette variety of grape and a second fermentation in the bottle to which a mixture of sugar and yeast has been added called “liqueur de tirage”.

There are nearly 300 wine producers in the area.

La Clairette de Die Méthode Ancestrale is made from the assembling of two grape varieties: the small graped white muscat (minimum 75%) and white clairette. The muscat with its small firm grapes contributes its sweetness and fruitiness and the clairette with its larger fruit brings the finesse.


Clairette de Die develops fruity and floral aromas. It suggests the fragrance of ripe summer fruit such as apricots and peaches.

The bouquet reveals the perfume of white flowers such rose, wild rose or honeysuckle. Its “robe” covers a range of hues from very pale yellow to gold.

Key figures

1910: Clairette de Die obtains the much sort after “Appellation d’Origine” label.

1942: Clairette de Die obtains the “Appellation d’Origine Contrôlée” label.

1971: The wine-making process for Clairette de Die Tradition is offically defined as “Méthode Dioise Ancestrale”.

The “Appellation d’origine” and the “Appellation d’Origine Contrôlée” are both labels that guarantee the production methods, provenance and quality of produce such as wine and cheese and other traditional products of the “terroir”.

The Crémant de Die is made in the same geographical zone as the Clairette de Die.

The grapes come from vines grown on small plots of land with clay and chalk soil along the Drôme Valley.

The vines can be found on the hillsides on the banks of the river between 200m and 700m altitude.

In the past, this “brut” white sparkling wine was made from just one clairette grape variety. Today the aligoté (10% to 40%) and the Muscat (5% to 10%) varieties are also used.


Apple and other green fruit notes that are characteristic of this wine emerge when tasting the Crémant, with its rich aromas, fine sparkle ending with a delightful freshness. Its “robe” is pale gold.

The wines of Châtillon en Diois

In the nineteenth century these wines were called the “Côtes du Bez” as this was the name of the tributary of the river Drôme that flows through the district.

The red and rosé are only produced in the two villages of Châtillon-en-Diois and Menglon.

The gamay noir variety of grape with white juice is used (75% minimum) as well as pinot noir and syrah.
