Famille Dubois.jpeg

A collaboration of three generations who share the same passion for the vine and the wines that come from it. Driven by a long experience and committed to research at the highest level, the Dubois family devotes itself entirely to the requirements of the development of Grands Crus.

The latest discoveries can be compared with old methods in order to discover and identify all the subtleties allowing the development of Chasselas, a grape variety which expresses so well the diversity of our terroirs.

Thus, Les Frères Dubois, firmly rooted in tradition, transmit, through their Crus, the image of a prestigious Swiss Vineyard.


It is in the Dézaley vineyard, created 800 years ago, that the Dubois Brothers have been perpetuating the winegrowing tradition since 1927.

The wines are aged in the deep cellars of the "Petit Versailles", a building built at the beginning of the 19th century and whose style was inspired by the golden rules of French architecture.

A modern pressing and vinification facility linked to the traditional maturation of the wines in large oak barrels brings out the characters and subtleties of our wines.


It is a collaboration of three generations who share the same passion for the vine and the wines that come from it. Driven by a long experience and attached to the research of the highest level, the Dubois family is dedicated to the requirements of the elaboration of Grands Crus.


From 2005, the third generation took over, propelling Frédéric and Grégoire to the head of the company. These entrepreneurial winegrowers complement each other admirably, supported by their wives, in a close and essential collaboration.

Frédéric and Séverine follow the work of the vineyard and the cellar, while Grégoire and Carla manage the administrative and commercial part with Daniel Rey, partner of the company.

Together, they are committed to maintaining the tradition of hospitality at the Petit Versailles and the high quality of its wines.


Some consider Chasselas as a specifically Swiss grape variety or at least from the Lake Geneva region.
One thing is certain: nowhere else does Chasselas produce such a subtle and complex wine as in Switzerland. Chasselas is the key grape variety for the white grape varieties of French-speaking Switzerland. Called Fendant in Valais because its skin splits under the fingers when it is ripe, it really took off in the middle of the 19th century, under the impetus of state structures. It is therefore the second most planted grape variety after Pinot Noir. Rather large cluster basking in the sun.
Precocious and vigorous, Chasselas adapts to a multitude of soils and climates and manages to restore the subtlety of each terroir beyond measure.

Malvasia is one of the oldest grape varieties in Europe. Imported from Greece in the 8th century, it probably originated in Asia Minor
In Puglia, there is a lot of wine made from blends with the famous Salice salentino (85% Negroamaro-15% Malavasia nera) and it is sometimes a small complement for certain primitivo, especially when the vintage is not easy.

These varieties love heat. That's why they are so good in southern Italy as well as in the neighboring ones. Besides, it is also famous in Sardinia.
Vinification: : the harvest takes place
second half of September.


Of late maturity, capricious, difficult to work, the Cornalin has
was nearly abandoned in the middle of the 20th century. Fortunately, the patience and perseverance of a few visionary winegrowers allow us to taste it even today!
In almost 25 years, the area of vines dedicated to this grape variety has increased tenfold in Valais, going from 14 ha in 1991 to 139 ha in 2015.
A success due to its high potential, comparable to that of great international red wines. Cornalin has an extraordinary fruity strength, an insolent youth, a body that is both slender and vinous, tonic and very fresh. It is unquestionably the greatest Valais red wine, Delicious young, on the fruit, it develops for a few years: its passion subdued, it then takes on a remarkable patina of finesse and nobility.

Pinot noir.jpeg

Originally from Austria, mainly established on the banks of the Rhine, in Germany, it appeared in the Rhone Valley in the middle of the 19th century.
Silvaner is the result of an old natural cross between Savagnin Blanc (Heida in Valais, Traminer in Tyrol) and an Austrian grape variety.
A little later than Chasselas, it is called Johannisberg in Valais.
Its aging potential and its complexity are unheard of and this beyond twenty years! The Johannisberg is mentioned in Valais
for the first time in 1862. It then designates Riesling. Its name certainly comes from the Château de Johannisberg in Moselle, the oldest Rieslinq estate in the world. Blanc du Rhin appeared at the same time and corresponded to Silvaner. But as early as 1928, current usage inverts the data and these two whites exchange their identities. The
specialists are offended by this but are forced to comply with practice.


This variety was obtained in 1970 at the Changins station and results from a cross between Gamay and Reichensteiner. It is a fairly vigorous variety which is very insensitive to gray rot.

Gamaret provides colorful and structured red wines, suitable for a certain ageing. The balance between alcohol and acidity is good. The characteristics of Gamaret make it particularly interesting in blending with Pinot Noir, Gamay and Garanoir.


Humagne Rouge is at the origin of full-bodied reds, with a beautiful dark ruby color. Château de Glérolles is the only producer not only in Lavaux but also in the Canton of Vaud to offer this grape variety, usually grown in the Aosta Valley or Valais.

Garanoir is a widespread grape variety in our regions. Its first name was Gastar, then Granoir and finally Garanoir. It can be considered from the same family as Gamaret because it also comes from a marriage between Gamay and Reichensteiner.

It is a colorful and supple wine. Its bouquet is complex and marked by notes of fruit and spices. In areas that are too hot, Garanoir can present imbalances between alcohol and acidity. It is well suited to blends by providing flexibility and power.


Merlot makes it possible to obtain round, powerful, rich wines with an intense garnet colour. Ideal for aging in barrels of full-bodied wines with supple tannins. Perfect for keeping.
