Henri Badoux operates in Chablais, the alpine wine region of Vaud in Switzerland, where cool-climate conditions shape distinctive red and white wines. The winery's portfolio centers on Cabernet Franc and Merlot—grapes that thrive in Chablais's demanding terroir—alongside Chasselas, the region's traditional white variety. Lettres de Noblesse Malbec - Cabernet Franc de Saphorin blends two dark varieties into a structured wine that has drawn assessment from Wine Spectator, Wine Advocate, and Decanter. The Lettres de Noblesse Merlot d'Yvorne showcases pure Merlot from the region's limestone soils. Petit Vignoble, a Chasselas expression, represents the lighter, mineral-driven character for which Vaud is recognized. The winery's approach emphasizes the specific microclimates of Chablais's named vineyard sites—Saphorin and Yvorne among them—where altitude and lake influence create conditions for both power and precision.
