Rosset operates in Valle d'Aosta, the Alpine valley in northern Italy where elevation and terroir define the character of the wines. The winery's portfolio centers on varieties suited to cool-climate viticulture: Syrah, Petite Arvine, and Chardonnay. The Syrah 870 Vallée d'Aoste draws from high-altitude fruit, expressing the structure and complexity typical of Syrah in mountain regions. Sopraquota 900, made from Petite Arvine—a local white variety—reflects the distinctive mineral and aromatic profile of Valle d'Aosta's indigenous grapes. The Chardonnay 770 rounds the range, offering the textural depth Chardonnay achieves at elevation. These wines have been assessed by Wine Enthusiast, Wine Advocate, and Decanter, positioning Rosset within the critical conversation around northern Italian alpine production.
