Vallerosa Bonci works with Verdicchio in Marche, the white-wine heartland of central Italy. The winery's portfolio centers on expressions from Castelli di Jesi, the region's flagship denomination. Pietrone Verdicchio dei Castelli di Jesi Riserva Classico represents the top tier—a riserva that shows the grape's capacity for structure and aging potential. Carpaneto Vineyard and San Michele, both Classico and Classico Superiore designations respectively, sit within the core range. Verdicchio from this zone is known for its mineral spine, green-fruit character, and crisp acidity. The wines have been assessed by Wine Advocate, Wine Spectator, and Wine Enthusiast.
