The Rosset Terroir winery was established in 2001 when the Rosset family began cultivating vineyards on their estate in the Senin area of Saint-Christophe, in the Aosta Valley. The first vineyard, covering approximately three hectares, was planted with Chardonnay, Syrah, and the indigenous Cornalin variety. Rosset Terroir produces around 50,000 bottles annually, focusing on sustainability and quality.
