In year 1931 Jakob Hammel began to develop the wine business with his son Richard, a business that he handed over to the latter in 1944. In 1947, Richard Hammel creates the public limited company HAMMEL S.A.. The same year, Mr. Charles Rolaz joined the company as a shareholder and director alongside Richard Hammel. Together, they give a great boost to the House which develops considerably. Today, Domaines Rolaz and Maison Hammel are among the most renowned producers in Switzerland. Owners and tenants of renowned Domaines, Clos and Châteaux, they control all stages of wine production, from growing the vines to bottling. The company cellars the harvest of nearly 150 ha of vineyards, including 8 estates owned in the cantons of Vaud (La Côte and Chablais) and Valais, and 8 other estates, partners for several generations (Vaud and Geneva), vinified, bred and marketed exclusively for Switzerland. One of those domaines is Château de Trévelin. Located in the heart of the Côte vineyards, on the edge of the old Roman via strata (route de l’Etraz), this elegant castle was built in 1577 on the ruins of a pagan temple of ancient Helvetia dedicated to the god Belin, deity invoked in particular for the fertility of crops, hence the name of Trévelin derived from ‘Terra Bellini’. Erected as a noble fiefdom in Bernese times, its prestigious 5.5-hectare vineyard estate was founded in the Middle Ages by the monks of the Abbey of Joux.
