Isabella and Stéphane Kellenberger are winemakers with passion and a sense for high quality products. They produce 16 different wines, made of international and indigenous grape varieties.

Situated in the vineyards of La Côte in Saint-Prex, a magnificent medieval village. Our estate overlooks Lake Geneva and the Alps. A south-facing hillside benefits from generous sunshine, rich soil and a great deal of passion. You'll receive a warm welcome from the Bugnon family. We have been cultivating the estate since the 4th generation. In 2023, we celebrated the 70th anniversary of our move from the old village of Saint-Prex to Bon-Boccard. Over the years, the estate has grown, and we now cultivate 8.3 hectares of vines. The grape varieties grown are Chasselas, Doral, Chardonnay, Gamay, Pinot Noir, Gamaret, Garanoir and Merlot. Our work is part of a constant quest for excellence, combining respect for the vines with the preservation of the winemaking traditions that have shaped our estate. Respect for the vines is at the heart of our approach. Each machine is operated with care, taking care not to disturb the natural balance of our terroir. We use methods that respect the environment, minimising our ecological footprint and preserving the biodiversity of our estate.
