Theres a touch of the tropical about this: aromas of mangoes & sweet spices. Chteau Roustit, near the convergence of icy River Ciron (rising from deep springs in Landes) & warmer Garonne benefits from autumn mists. These generate the noble rot that shrivels grapes to syrupy succulence. M. Dubourg oversees successive sweeps through his vines, picking optimally wrinkly grapes. His Semillon-Sauvignon-Muscadelle makes a fine dessert wine thats also good with grilled fish.
