Contadi Castaldi produces sparkling wines in Franciacorta, Lombardia's prestigious region for méthode champenoise bottlings. The winery's portfolio centers on Chardonnay and Pinot Nero—the classic grapes of the appellation—crafted into elegant, structured cuvées. The Franciacorta Blànc, a blend of Chardonnay and Pinot Blanc, represents the house's refined approach to the region's signature style. Pinò Nero Natura Franciacorta showcases the darker fruit and mineral precision of Pinot Nero in a dosage-free expression. The Franciacorta Zero, built from Chardonnay and Pinot Nero, extends the range into bone-dry territory. These wines have been assessed by major critics including Wine Enthusiast, Wine Advocate, Decanter, Wine Spectator, and Falstaff, reflecting the winery's standing within Italy's sparkling wine landscape.
