In the heart of the Bugey terroir, Yves Duport organically and biodynamically manages the family estate and continues to enhance his expertise gained since four generation winemakers. He is one of the star winemakers from this appellation and his wines are all produced using the methode champenoise. His Bugey vineyard is 500 hectares and AOP since 1958. The monks were the first to plant vines in the region around the year 1115. The Bugey wines utilize the Mondeuse and Rousette native varietals and share the Pinot Noir, Chardonnay and Aligoté varietals with Bourgogne. Yves Duport's estate enjoys terroir diversity. The Montagnieu slopes with white marl clay are an ideal spot for Altesse de Montagnieu (Rousette) and Mondeuse. The Chardonnay prefers the silica and limestone of the moraine slopes, and the Pinot Noir goes well in the clay and limestone mountain. The second generation at the estate, Yve's grandfather, started the bulk wine production in 1938. Today, Yves, who still lives in the same village of Groslée, produces and bottles 140.000 bottles with only three employees. His estate was certified organic in 2009 and he is the only organic Altesse de Montagnieu winegrower (1,2ha out of 30 ha). He uses native yeast and oak barrel for the red aging which also differenciates him from other Bugey producers.
