The Roh family has its origins in Alsace having crossed the mountains into the Swiss Valais during the 17th century. They settled in the town of Conthey which eventually in 1862 was split into two communes: Conthey and its neighbor, Vétroz. It is in the latter village that the Roh family and its cave are located, essentially in the heart of the Valais. The Roh family has assembled an impressive selection of vineyards and cepages, almost all of which are situated within the confines of Vétroz and Conthey.
