A winery with a hundred years of history

The Domaines Les Frères Dubois, also known as Domaine Les Frères Dubois, exemplify the long tradition of Vaudois viticulture. Since 1927, the Dubois family has been dedicated to winegrowing in the heart of the Dézaley, one of the most historic wine regions in Switzerland with a history stretching back over 800 years. The winery is closely linked to the historic Le Petit Versailles building, an impressive structure dating back to the 19th century. This house is still the center of wine production today and impressively embodies the combination of French architecture and regional wine culture. The winery is located at the address Ch. de Versailles in Cully, and Le Petit Versailles is known as a striking building on the de Versailles.

Over several generations, the Dubois have continued to develop their wines with great dedication. Respect for the terroir, craftsmanship and openness to new ideas characterize the winery’s self-image. This balance of preservation and further development has secured the Domaines Les Frères Dubois a firm place in the Swiss wine scene.

Philosophy and claim

The philosophy of Domaines Les Frères Dubois is based on the conviction that great wines must reflect their origins. Here, tradition is not understood as a standstill, but as a foundation for contemporary interpretation. With sustainable cultivation methods and precise vinification, the aim is to bring out the full natural potential of the grapes.

Special attention is paid to crus from first-class vineyards that stand for the highest quality. The aim of the company is clear: to produce wines that radiate authenticity, show character and offer enjoyment at a high level. For the Dubois family, wine is a cultural asset that brings people together and tells stories.

Viticulture and production

Winegrowing at Domaines Les Frères Dubois is deeply rooted in regional tradition, but is complemented by modern technology. Wines with elegance and balance are produced in the historic cellars of Le Petit Versailles. Chasselas, the leading grape of the Vaud region, plays a central role here, producing particularly complex and terroir-driven wines in Dézaley.

The range is complemented by Pinot Noir and Merlot, whereby each grape variety is vinified separately and with great care. Gentle handling of the grapes, reduced intervention and careful ageing characterize the work in the cellar. The wines are suitable both as an accompaniment to a fine meal and as an appreciated gift. The Chasselas in particular shows its strengths in combination with cheese or at convivial gatherings and stylish dinners.
