Domaine de Montbourgeau produces wines from Côtes du Jura, the heart of France's distinctive Jura region. The winery focuses on the grapes that define the area: Savagnin and Chardonnay, varieties that thrive in Jura's continental climate and limestone soils. L'Etoile Vin Jaune, made from Savagnin, represents the region's most iconic expression—a wine of oxidative aging and mineral complexity. The Vin de Paille, also Savagnin-based, captures the sweetness of late-harvest fruit dried on straw. En Banode L'Etoile blends Chardonnay and Savagnin, bridging the region's white wine traditions. These wines have been assessed by Decanter, Wine Advocate, and Wine Spectator.
