The Valle d’Aosta is a deep valley that runs east to west, closed off just before the French border by some of the highest peaks in the Alps. Vineyards here are like little gardens clinging to steep south-facing mountainsides, where only a thin layer of sandy topsoil lines the hard granite bedrock. Abundant direct sun and cold nights amplify the aromatic expression of the local grapes while preserving zingy acidity, a recipe for delicate, perfumed wines that dance energetically across the palate. Sipping Feuillet's Petite Arvine evokes the euphoria of running through a field of Alpine wildflowers—admittedly a cliché, until you feel the exacting mineral purity of this floral bianco wash over your senses.
