Growing grapes at Château Feuillet, in northwest Italy’s Valle d’Aosta, is not like farming anywhere else. Feuillet’s vineyards scale steep mountain slopes in the heart of the Alps—this is extreme viticulture at its finest. At 700 meters above sea level, the high altitude ensures chilly nights throughout the growing season, yet the sheer gradient and perfect southeast exposure allow for adequate direct sunlight that imbues excellent ripeness year after year. These somewhat paradoxical conditions account for the wines’ unique balance, where sumptuous fruit mingles with explosive bright acidity to give pristinely refreshing, wildly aromatic Alpine libations. Feuillet lies at the core of the Torrette growing region, where the Petit Rouge grape finds its greatest expression. Here it is blended with a splash of Mayolet, another local variety, and matured in stainless steel. A slight chill will elevate this jubilant red’s crunchy minerality and suggestions of mountain wildflowers and fresh berries.—Anthony Lynch
